Although scholars have often settled upon 1686 as the year in which the central elements of Leibniz’s philosophy first appear in systematic form, certain of his positions appear to have been firmly in place at least ten years earlier. Papers written in 1676 reveal that Leibniz had already by that time established the fundamental feature of his single-substance metaphysics: the insubstantiality of matter. As he defines it, matter is a mode, but a mode of peculiar status, a sort of “top (...) mode,” which, together with change, is requisite to the existence of any other modes, or “things.” Things for Leibniz include all bodies and their qualities, and in some places also appear to include minds, although Leibniz for religious reasons equivocates here, and wants to resist. Nevertheless, Leibniz’s desire to move toward a version of the Aristotelian notion of matter as the principle of individuation is clearly in evidence as he works to set out a view which can accommodate mechanistic physics while avoiding the perceived atheistic threat inherent in both Cartesian dualism and Spinozistic monism.

This essay offers an alternative account of Leibniz’s views on substance and fundamental ontology. The proposal is driven by three main ideas. First, that Leibniz’s treatment should be understood against the backdrop of a traditional dispute over the paradigmatic nature substance as well as his own overarching conciliatory ambitions. Second, that Leibniz’s metaphysics is intended to support his conciliatory view that both traditional views of substance are tenable in at least their positive and philosophical respects. Third, that the (...) relationship between immaterial substances, corporeal substances, and ordinary bodies in Leibniz’s metaphysics is best understood as one of “material” constitution. The interpretation as a whole thus suggests that Leibniz needn’t be read as offering either an exclusive defense of corporeal substance realism, nor of immaterial substance idealism, nor as being deeply torn (at a time or over time) between two such views. He may instead be seen as offering a carefully presented, consistent, and sophisticated conciliatory account of substance. (shrink)

In this paper, I address a topic that has been mostly neglected in Leibniz scholarship: Leibniz’s conception of number. I argue that Leibniz thinks of numbers as a certain kind of relation, and that as such, numbers have a privileged place in his metaphysical system as entities that express a certain kind of possibility. Establishing the relational view requires reconciling two seemingly inconsistent definitions of number in Leibniz’s corpus; establishing where numbers fit in Leibniz’s ontology requires confronting a challenge (...) from the well-known nominalist reading of Leibniz most forcefully articulated in Mates. While my main focus is limited to the positive integers, I also argue that Leibniz intends to subsume them under a more general conception of number. (shrink)

Most commentators agree that Leibniz advocates some version of a doctrine of the ideality or reducibility of relations, but there is considerable disagreement about what exactly this doctrine means. I argue that Leibniz’s views on relations are more complex than has been previously appreciated, and that, despite some ‘reductionist’ strands in Leibniz’s position, it is seriously misleading to describe him as a reductionist about relations without adding some important qualifications. The complexity of Leibniz’s views on relations tends to be obscured (...) by the common assumption that they can be captured in one unified thesis, or a small number of closely related theses, and by the widespread neglect to take Leibniz’s division of reality into several ontological levels into consideration. I disentangle ten Leibnizian theses about relations, extrinsic denominations, and their relation to intrinsic denominations. Some of these theses express a kind of dependence of extrinsic denominations on intrinsic ones, and some of them can even be counted as articulations of a form of reductionism. But, overall, the general tenor of Leibniz’s position on extrinsic denominations remains non-reductionist. (shrink)

In this article, I revisit Leibniz's early views on physical causation, more specifically, his relation to physical occasionalism focusing on the period from 1668 to 1676. An in-depth analysis of the Confession of Nature against the Atheists taken together with the Catholic Demonstrations, Leibniz's correspondence with Jakob Thomasius from 1668/69, and the Pacidius Philalethi (1676) serve as evidence that his position leads to physical occasionalism. This receives further confirmation by taking into account Leibniz's familiarity with Weigel's occasionalism in contrast to (...) Leibniz's later encounter of French occasionalism à la Cordemoy, La Forge, or Malebranche. Leibniz's exposure to Weigel's occasionalism, in turn, helps us better understand Leibniz's later critical reaction to occasionalism and how occasionalism helped him develop his own distinct views on causation as expressed in his mature philosophy.

Leibniz's principle of sufficient reason is the claim that everything has a sufficient reason. But is Leibniz committed to the necessity or to the contingency of his great principle? I argue that Leibniz is committed to its contingency, given that he allows for the absolute possibility of entities that he claims violate the PSR. These are all cases of qualitatively indiscernible entities, such as indiscernible atoms, vacua, and bodies. However, Leibniz's commitment to the contingency of the PSR seems to stand (...) in tension with his inference of the PSR from his theory of truth. I argue that this apparent tension can be resolved satisfactorily. When it comes to his modal views on the PSR, Leibniz's position is entirely consistent. (shrink)

In his Essays on the Intellectual Powers of Man Thomas Reid draws an analogy between his notion of the self and Leibniz’s notion of a monad. Reid formulates this analogy in order to highlight what he considers to be the essential feature of the self: its unified and indivisible structure. This paper considers Reid’s analogy in the specific context of the diachronic aspect of substantial unity. Its focus is specifically on the role that the idea of continuity plays in establishing (...) the unity and indivisibility of the entities in question (viz., the self and the monad). As part of the ongoing debate over Leibniz’s mature metaphysics of substance, this paper highlights the positive implication of Reid’s analysis of the self (usually viewed as a critical reaction to Locke and Hume) and its place within the early modern debate over the nature of substantial unity.

The advance of mechanism in science and philosophy in the 17th century created a great interest to machines or automata. Leibniz was no exception - in an early memoir Drôle de pensée he wrote admiringly about a machine that could walk on water, exhibited in Paris. The idea of automatic processing in general had a large role in his thought, as can be seen, for example, in his invention of the binary code and the so-called Calculemus!-model for solving controversies. In (...) metaphysics, the idea of an automata was expressed most clearly in the 1695 article New System of the Nature of Substances and their Communication, and the ensuing correspondence with, among others, Foucher, Bayle, Lamy, Jaquelot and Masham. In the article Leibniz discusses the soul as a spiritual machine in the context of pre-established harmony, arguing that God can "give to a substance at the outset a nature or internal force which could produce in it an orderly way (as in spiritual or formal automaton; but a free one, in the case of a substance which is endowed with a share of reason) everything that is going to happen to it, that is to say, all the appearances or expressions it is going to have, and all without the help of any created thing." The basic idea of Leibniz's spiritual machine is that the soul or entelechy is an autonomous and spontaneous unity, consisting of internal active force and producing its own perceptions (both confused and distinct). It is a self-moving machine, driven by its perceptions and appetites, but it follows (without being conscious of it) a lawful series or programme created by God. The entelechy remains the same despite undergoing an infinite number of changes. To Foucher he explained that each state of the individual substance is a consequence of its preceding one, "as if there were only God and the substance in the world". Despite this, the spiritual machine is related not only to God, but through the pre-established harmony to bodies or natural machines. However, as it is not dependent on them, the spiritual machine is superiot to natural machines. In this paper I concentrate on three moral themes related to the spiritual machine: moral deliberation, moral identity and the goal of moral action. All these themes are more or less implicit in the New System, but are discussed in more detail in the ensuing correspondence after the publication of the article. Finally, the themes are given an extended discussion especially in the second book of New Essays on Human Understanding (1704, published 1765), written partly at the same time as some of the correspondence and unpublished related material. I will first give an overview of Leibniz's position concerning the spiritual machine or automaton in the New System and then go on to explore the three moral themes one by one, as they feature in the subsequent correspondence and in the New Essays. I will show that the three topics are essential to the function of the spiritual machine – to Sophie Charlotte Leibniz wrote: "...let us say that everything in bodies happens mechanically, or in accordance with laws of motion, and that everything in the soul happens morally, or in accordance with perceived good or evil." There are many texts that anticipate the views in the New System (notably the unpublished memoir De Affectibus of 1679) and Leibniz continued to discuss its themes later on (in addition to correpondence, for example, in Theodicy of 1710 and Monadology and Principles of Nature and Grace of 1714). Here I focus on the short-term development of Leibniz's views on the topic (around 1695-1705), but I argue that his basic view of the spiritual machine did not change much after finishing the dialogue with Locke in 1704.

The relation between leibniz's logical and his metaphysical views is the subject of much modern scholarship. Some commentators have argued that his metaphysics is based on his logic; others have taken the opposite position. However, Both sides pose the question in terms of 'priority'. On the contrary, I argue that it is likely that leibniz means the psr to play "both" a logical and a metaphysical role. The ambiguity of leibniz's psr indicates that he equates the metaphysical notion of causation (...) with the logical notion of deduction. The psr's ambiguity results less from any confusion on leibniz's part between the notions of cause and reason, Than from his desire to identify logic and metaphysics. That identity is achieved not by reducing one to the other, But by incorporating them on an equal basis into a single discipline. (shrink)

It has recently been suggested that, for Leibniz, temporal facts globally supervene on causal facts, with the result that worlds differing with respect to their causal facts can be indiscernible with respect to their temporal facts. Such an interpretation is at variance with more traditional readings of Leibniz’s causal theory of time, which hold that Leibniz reduces temporal facts to causal facts. In this article, I argue against the global supervenience construal of Leibniz’s philosophy of time. On the view (...) of Leibniz defended here, he adopts a non-modal reduction of time to events, a form of reductionism that entails a strong covariation between a world’s temporal facts and its causal facts. Consequently, worlds discernible with respect to their temporal facts must be discernible with respect to their causal facts, and worlds discernible with respect to their causal facts must be discernible with respect to their temporal facts. This position strongly favors the standard identificatory reduction of time to causation often imputed to Leibniz. (shrink)

Between 1701 and 1705 Leibniz focused on the task of securing theological reunion between Lutherans and Calvinists, the two major Protestant sects at the time. Doing so, he believed, required reconciliation on two key topics, namely, the doctrine of the Eucharist, and the doctrine of election. To bring unity on the second issue, Leibniz composed a lengthy treatise based on a commentary on the Thirty-nine articles of the Church of England. This treatise stakes out a position springing from Leibniz’s own (...) views. In this essay, I examine the views Leibniz defends in this treatise. I show that Leibniz’s views are much friendlier to the Arminian perspective than to the Calvinist one. I also show that this result is surprising since Arminian views seem incompatible with views on freedom and the problem of evil standardly attributed to Leibniz. This lack of fit should compel a re-examination of these standard attributions. (shrink)

A certain tension underlies any account of how we engage the thought of another culture. In order to learn from another culture, we must be able to judge what is of value to us, which means we must retain some criterion for judgment. At the same time, in so far as we presuppose some criterion, we place that criterion itself out of question. In my dissertation, I approach this tension through Wilhelm Gottfried Leibniz, concentrating on two related aspects of his (...) philosophy. The first is that perfection requires the maximization of diversity and order. In uniting diversity and order, Leibniz lays the foundation for uniting an order allowing judgment with the actual diversity of cultures. The second aspect is the characterization of the relationship between experience and the universe as expression, rather than representation. The maximization of order and diversity yields a system in which each substance expresses the same universe from a different perspective. ;What do substances with diverse perspectives share? We might expect Leibniz to posit necessary truths as the common ground, but although necessary truths are universal, our access to them is limited. The specific form these limitations take depends on our concrete placement in the universe, and thus our perspective. I examine four ways in particular that our perspectival experience conditions our access to necessary truths. For example, our finitude requires that our discovery of necessary truths follow a concrete order, determined by experience. Thus a contingent encounter with a geometry school makes us more likely to learn necessary truths about geometry. ;The first half of my dissertation provides a broad interpretation of Leibniz's philosophy, setting up this foundation for cultural exchange. The second half is a comprehensive study of Leibniz's writings on China, in which this foundation is expressed. Through this study, I show how Leibniz himself conceives of understanding across cultures, while also showing how Leibniz's interests in China follow from foundations in his philosophy. I conclude by arguing that Leibniz's vision of different substances as expressions of the same universe provides a fruitful foundation for cultural exchange. (shrink)

Hong Kong, as a former colony of the United Kingdom, is characterised as a hybrid of East and West. Its colonial history is commonly seen as establishing many positive aspects of Hong Kong and shaping good qualities of its people, such as the value of rule of law, free speech, freedom of the press, and fluency in English. Yet the majority of people in both Hong Kong and China share Han Chinese ethnicity, which has been used by both (...) the Chinese and Hong Kong governments to promote a blood-based idea of Chinese identity for decades. This paper explores “Chineseness", or Chinese identity, as promoted by the Hong Kong government. It first explores the concept of Chineseness, elaborating on a blood-based view that connects with ethnic-nationalism, in contrast with a pluralistic view of identity in the Hong Kong context. The paper then examines how Hong Kong government officials promote Chineseness through major outlets, on government websites and in speeches captured in media. As we show, the government tends to advocate a blood-based view of Chineseness akin to ethnic-nationalism. A more inclusive and pluralistic view which recognises the dynamic nature and multiple visions of Chinese identity better fits Hong Kong’s multicultural context. (shrink)

Leibniz has long faced a challenge about the coherence of the distinction between necessary and contingent truths in his philosophy. In this paper, I propose and examine a new way to save genuine contingency within a Leibnizian framework. I conclude that it succeeds in formally solving the problem, but at unbearable cost. I present Leibniz’s challenge by considering God’s choice of the best possible world (Sect. 2). God necessarily exists and necessarily chooses to actualise the best possible world. The actual (...) world therefore could not be different, for if it were different it would be a distinct and inferior world and hence would not be created. In Sect. 3 I defend Leibniz from this challenge. I argue that while it is necessary for God to choose to create the best possible world, it is not necessary for any world to be the best possible. This is because the criterion for judging perfection can itself be contingent. Different criteria will judge different worlds as the best. Thus it is necessary for God to create the best, but not necessary which is the best. Distinguishing between possible worlds in Leibniz’s sense and in the modern sense allows a fuller exposition of this position. There are worries that can arise with the claim that the criterion of perfection is contingent. I consider two of the most pressing (Sect. 4). The first argues that the criterion is in God’s understanding and hence is necessary; the second alleges that a contingent criterion of perfection violates Leibniz’s cherished Principle of Sufficient Reason. These worries are well-grounded, and examining them reveals a deep incompatibility between this solution and Leibniz’s metaphysical views. I conclude that there is a real solution available, but that it is unacceptable to Leibniz or a Leibnizian. The search for a genuine solution that is genuinely Leibnizian goes on. (shrink)

This article presents a corpus-assisted discourse study of the representations of China’s smog in one Chinese and three Anglo-American English-language newspapers from 2011 to 2014. The findings suggest that they converge in representing China’s smog as a kind of severe air pollution that has some consequences on residents in China and poses a problem that the government must tackle. However, the Chinese English-language newspaper prefers to represent it as a kind of weather phenomenon without serious impact on (...) public health and to construct a positive and responsible image of the Chinese central government. The Anglo-American English-language newspapers are inclined to dramatize it as a disaster with a huge health impact, and construct a negative image of the Chinese government with a view to pressurizing it to take responsibility in the context of climate change.

In discussion of Leibniz’s philosophical methodology Donald Rutherford defends the view that Leibniz regarded metaphysics as an a priori demonstrative science. In the course of this discussion Rutherford isolates and tries to deflect a significant challenge for his view, namely the observation that in many of his mature writings on metaphysics Leibniz appears to defend his views by means of a posteriori arguments. I present some prima facie difficulties with Rutherford’s position and then offer an alternative account of (...) how Leibniz thought he needed to establish metaphysical claims. My suggestion is that the challenge that Rutherford poses may be best answered by attending to the fact that Leibniz recognized a kind of metaphysical enquiry, ‘real metaphysics’, that is essentially a posteriori, in virtue of the fact that it is concerned not just with possible kinds of beings, but with the kinds of beings that God actually created.

This chapter seeks to highlight some of the main threads that Leibniz used in developing his views on infinity in his early years in Paris. In particular, I will be focusing on Leibniz’s encounters with Descartes, Galileo, and Spinoza. Through these encounters, some of the most significant features of Leibniz’s view of infinity will begin to emerge. Leibniz’s response to Descartes reveals his positive attitude to infinity. He rejects Descartes’s view that, since we are finite, we cannot (...) comprehend the infinite and therefore should refrain from studying it. Likewise, Leibniz rejects Descartes’s view that the term ‘infinite’ should be reserved to God alone, as well as Descartes’s distinction between the infinite and the indefinite. Leibniz’s encounter with Galileo brings out his rejection of infinite number in response to Galileo’s paradox. This, in turn, leads him to face another formidable challenge, viz., to defend the claim that an infinite being is possible, while an infinite number is not. Leibniz’s encounter with Spinoza, I suggest, highlights the way he is approaching this problem by distinguishing between quantitative and non- quantitative senses of infinity. The strategy of employing different senses of infinity in different contexts will remain central in Leibniz’s approach to infinity for the rest of his career. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Leibniz’s Political and Moral Philosophy in the Novissima Sinica, 1699–1999Patrick RileyThe Preface to Leibniz’s Novissima Sinica 1 contains an important but highly compressed and abbreviated quintessence of his theory of justice or jurisprudence universelle—a version so compressed and abbreviated that one must have a broader and fuller understanding of this universal jurisprudence before one can entirely appreciate what Leibniz has to say about Christian charity, Platonism, and geometry in (...) the Novissima Sinica itself. Above all, one wants to know why Leibniz, in the key paragraph of the Preface to Novissima Sinica, should describe the Chinese emperor as just and charitable and as a (more or less) “Platonic” geometer who is as wise as he is charitable. And why should Leibniz contrast this “wisely charitable” Chinese ruler with the Pontius Pilate who irresponsibly asked, “What is truth?” and then permitted the judicial murder of the very Christ who did most to make charity and justice coextensive by saying, “A new law I give unto you, that ye love one another”? 2 The wise course, therefore, is to throw enough light on Leibnizian universal jurisprudence in general to make his moral-political utterances in Novissima Sinica intelligible in particular.In 1693, four years before the publication of Novissima Sinica, Leibniz revealed the outlines of his jurisprudence universelle in the Codex Iuris Gentium:a good man is one who loves everybody, so far as reason permits. Justice, then, which is the virtue which regulates that affection which [End Page 217] the Greeks call philanthropy, will be most conveniently defined... as the charity of the wise man, that is, charity which follows the dictates of wisdom... Charity is a universal benevolence, and benevolence the habit of loving or of willing the good. Love then signifies rejoicing in the happiness of another..., the happiness of those whose happiness pleases us turns into our own happiness, since things which please us are desired for their own sakes. 3Slightly later, in La véritable piété, Leibniz indicated what this view of justice entails:those who... reduce justice to [mere] rigor, and who fail altogether to understand that one cannot be just without being benevolent... in a word, not only those who look for their profit, pleasure, and glory in the misery of others, but also those who are not at all anxious to procure the common good and to lift out of misery those who are in their care, and generally those who show themselves to be without enlightenment and without charity, boast in vain of piety which they do not know at all, whatever appearance they create. 4The central idea of Leibniz’s “universal jurisprudence,” which aims to find quasi-geometrical, eternal moral verities equally valid for all rational beings, human or divine, is that justice is “the charity of the wise” (caritas sapientis), 5 that it is not mere conformity to sovereign-ordained “positive” law given ex plenitudo potestatis (in the manner of Hobbes); nor is it mere “refraining from harm” or even “rendering what is due” (the neminem laedere and suum cuique tribuere of Roman law). 6 The equal stress on “charity” and on “wisdom” suggests that Leibniz’s practical thought is a kind of fusing of Platonism—in which the wise know the eternal truths such as absolute goodness (Phaedo 75d), which the gods themselves also know and love (Euthyphro 93-10e) and which therefore deserve to rule (Republic 443d-e) 7 —and of Pauline Christianity, whose key moral idea is that charity or love is the first of the virtues (“though I speak [End Page 218] with the tongues of men and of angels, and have not charity, I am become as sounding brass or a tinkling cymbal”). 8 Historically, there is nothing remarkable in trying to fuse Platonism and Christianity. Augustine’s thought (particularly the early De Libero Arbitrio) is just such a fusion. 9 But Leibniz was the last of the great Christian Platonists, and left the world just as Hume, Rousseau, and Kant were about to transform and “secularize” it.I. If one decomposes caritas sapientis into its parts, charity and wisdom, the provenance of both elements is clear enough... (shrink)

This accommodation of differences is rooted in the belief that the most perfect possible world maximizes both diversity and harmony. In a time of rapid globalization, as the imperative to maximize diversity and harmony grows, I believe it is worthwhile to turn our attention to Leibniz's philosophy, particularly as it is expressed in his writings on China. The ground of Leibniz's openness toward other cultures is different from the ground to which we are accustomed. Multiculturalism is usually grounded in skepticism. We should accept and tolerate others because we can never be certain that our own beliefs are correct. The ground of Leibniz's tolerance leads in the opposite direction—we should [End Page 447] accept others not because no one knows the truth but because everyone knows something of the truth. 2The well-known metaphor of monads as perspectives on a city illustrates this approach. Leibniz writes, "Indeed, all individual substances are differentexpressions of the same universe and different expressions of the same universal cause, namely God. But the expressions vary in perfection, just as different representations or drawings of the same town from different points of view do." 3 The metaphor of different monads as different perspectives on a town captures what is needed for cultural exchange. What each of us "sees" is not wrong but partial or perspectival. Because our view is limited, we must learn from others whose views have different limitations, and we must be careful not to force our perspective on others. At the same time, each perspective is grounded in truth, which is what Leibniz intends when he says that each monad expresses the same universe. That is said to express a thing in which there are relations [habitudines] which correspond to the relations of the thing expressed. But there are various kinds of expression.... What is common to all these expressions is that we can pass from a consideration of the relations in the expression to a knowledge of the corresponding properties of the thing expressed. Hence, it is clearly not necessary for that which expresses to be similar to the thing expressed, if only a certain analogy is maintained between the relations. 4Leibniz gives many examples. An idea expresses its object. The perception of a monad expresses the universe, and the understanding of a mind expresses the understanding of God. Every effect expresses its cause. The senses and secondary qualities express their objects, as well as the body and its organs. Definitions express the essence of what they define. Paintings express the cities they represent. What do such dissimilar relationships have in common? The two things need not be similar but their conditions must be analogous. In the New Essays Leibniz writes that the resemblance is a relation of order, as an ellipse resembles the circle whose projection it is, "there is a certain precise and natural relationship between what is projected and the projection which is [End Page 448] made from it, with each point on the one corresponding through a certain relation with a point on the other." 5 In the Theodicy Leibniz says that the representation has a natural relationship to what is represented. If this representation is imperfect, then it... (shrink)

Why was Leibniz so fascinated by Chinese philosophy and culture? What specific forms did his interest take? How did his interest compare with the relative indifference of his philosophical contemporaries and near-contemporaries such as Spinoza and Locke? In this highly original book, Franklin Perkins examines Leibniz's voluminous writings on the subject and suggests that his interest was founded in his own philosophy: the nature of his metaphysical and theological views required him to take Chinese thought seriously. Leibniz was unusual in (...) holding enlightened views about the intellectual profitability of cultural exchange, and in a broad-ranging discussion Perkins charts these views, their historical context, and their social and philosophical ramifications. The result is an illuminating philosophical study which also raises wider questions about the perils and rewards of trying to understand and learn from a different culture. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Leibniz and China: A Commerce of LightRobin R. WangLeibniz and China: A Commerce of Light. By Franklin Perkins. Cambridge: Cambridge University Press, 2004. Pp. xvi + 224.In December 1697, Gottfried Wilhelm Leibniz (1646-1716) wrote to a Jesuit friend in China, praising the Jesuit mission there as "the greatest affair of our time" (p. 42). The purpose of that mission, in Leibniz's view, was not (...) simply to glorify God and to spread Christianity; it was also being undertaken for the good of humanity and the growth of human knowledge. He went on:For this is a commerce of light, which could give to us at once their work of thousands of years and render ours to them, and to double so to speak our true wealth for one and the other. This is something greater than one thinks.(p. 42)Why was Leibniz, unlike his contemporaries Locke and Spinoza, so enthusiastic about other cultures, especially Chinese culture? Why, in contrast to the scholars of today who claim that philosophy is the privilege of the Western mind and who dismiss philosophical exchange as useless, was Leibniz able to understand the importance of cultural exchange? And why is it that his "commerce of light" can still illuminate our path toward wisdom in this age of globalization? In a well-researched and carefully crafted monograph, Leibniz and China: A Commerce of Light, Franklin Perkins answers these questions with compelling evidence and persuasive argument.To emphasize the significance, magnitude, and relevance of cultural exchange Perkins organizes his book thematically in five chapters. The first chapter provides the historical context of the world in which Leibniz lived. Perkins cites well-documented events to illustrate how Europeans first encountered other cultures and the "three lenses" through which they viewed them (p. 12). This exploration sets the stage for understanding Leibniz's knowledge of China and his basic orientation toward learning from diversity.In chapter 2 Perkins challenges current scholarship and makes the critical claim that Leibniz's interest in China and cultural exchange was "not accidental" (p. 45), but rather flowed from his own distinctive philosophical system. This argument distinguishes Perkins's innovative approach from the mainstream traditional scholarship on Leibniz. He claims that Leibniz was "a more pragmatic, empirical and fallibilistic investigator of the world," that he was "motivated by practical and theological concerns," and that he was "a pluralistic thinker" (p. 45). To support his argument, Perkins discusses Leibniz's "monads" in the context of order, diversity, and perfection. Each monad is a different manifestation of the same universe, yet one unitary universe is multiplied by its expression in diverse monads. God chose to create a world exemplifying the utmost perfection, with "the greatest possible combination of order and diversity" (p. 44). Diversity is essential to the perfection of the world since the most perfect possible world maximizes the greatest order. This intrinsic relation between order, diversity, and perfection creates an unqualified need for cultural exchange because order requires diversity for perfection, and an ordered diversity only amplifies the magnificence of its Creator. On a metaphysical level, cultural exchange for Leibniz [End Page 111] was "driven by the value of diversity in the best possible world and the derivation of diversity from variations in monadic perspectives. On an epistemological level, exchange was driven by the necessary limits of our own perspective and the fact that monads in distant places have different and complementary perspectives" (p. 108).After laying out the philosophical foundation for cultural exchange in Leibniz's system, Perkins turns his discussion to Leibniz's specific connection with China. In chapter 3 he offers a historical narrative that traces the development and growth of Leibniz's interest in and knowledge of China. Leibniz's first mention of China was in his De Arte Combinationis in 1666, when he was only twenty years old (p. 109). Through his massive correspondence with Jesuits in China and his active social participation in controversies around the Jesuit mission, Leibniz's knowledge of China grew in depth and sophistication as the decades passed. His initial approach to China reflected "his interest in international politics and economics" (p. 113). But this practical focus was... (shrink)

In the present book, Pauline Phemister argues against traditional Anglo-American interpretations of Leibniz as an idealist who conceives ultimate reality as a plurality of mind-like immaterial beings and for whom physical bodies are ultimately unreal and our perceptions of them illusory. Re-reading the texts without the prior assumption of idealism allows the more material aspects of Leibniz's metaphysics to emerge. Leibniz is found to advance a synthesis of idealism and materialism. His ontology posits indivisible, living, animal-like corporeal substances as the (...) real metaphysical constituents of the universe; his epistemology combines sense-experience and reason; and his ethics fuses confused perceptions and insensible appetites with distinct perceptions and rational choice. In the light of his sustained commitment to the reality of bodies, Phemister re-examines his dynamics, the doctrine of pre-established harmony and his views on freedom. The image of Leibniz as a rationalist philosopher who values activity and reason over passivity and sense-experience is replaced by the one of a philosopher who recognises that, in the created world, there can only be activity if there is also passivity; minds, souls and forms if there is also matter; good if there is evil; perfection if there is imperfection.

As Leibniz points out in the Méditation sur la notion commune de la jus tice, justice—defined as charity of the wise and universal benevolence—belongs “to the necessary and eternal truths about the nature of things, as numbers and proportions.” According to the interpretation of Patrick Riley, from this perspective the two manuscripts usually regarded as belonging to the Méditation should be seen as complementary parts of a unitary Platonizing work. According to Riley, the manuscript that now constitutes the first part (...) of the Méditation is concerned with definitions of ethical concepts viewed as “quasi-mathematical, demonstrable ‘eternal verities’”, whereas the manuscript that now constitutes the second part of the Méditation is concerned “with Platonic ‘ascent’, in the manner of Phaedrus and Symposium,” which recommends the transition from mere negative forbearance from harm to doing positive good. In formulating these claims, Riley uses scare quotes to indicate that he uses the terms “eternal verities” and “ascent” in an unusual way that diverges from the views of the historical Plato. According to his interpretation, Leibniz’s modifications of Platonism are restricted to peripheral parts such as the doctrine of the pre-existence of the soul or Pythagorean components such as the doctrine of metempsychosis. Therefore, Riley claims that when Leibniz is talking about knowing eternal truths, what he has in mind is literally the view that we know the same truths as the truths that the gods know and love but do not cause or change.

In what countries and among which individuals in Asia is China's influence seen as least favorable? Drawing upon AsiaBarometer survey data from 12 Asian societies between 2006 and 2008, this study tests a series of hypotheses aimed at identifying those variables that most consistently predict individuals’ perceptions of China. With the exceptions of Japan, South Korea, Taiwan and Vietnam, a clear plurality or a majority of respondents in each polity views China's influence positively. Concerns about domestic economic (...) management were most consistently associated with perceptions of China that are more unfavorable, while greater levels of contact with the Chinese film and television culture were consistently associated with perceptions of China that are more favorable. These results suggest that China is more likely to be seen as an economic rather than military threat by Asian publics, and that Asia may prove responsive to a nuanced soft power campaign by Beijing in the future.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Leibniz and the Natural World: Activity, Passivity, and Corporeal Substances in Leibniz’s PhilosophyMichael FutchPauline Phemister. Leibniz and the Natural World: Activity, Passivity, and Corporeal Substances in Leibniz’s Philosophy. New Synthese Historical Library, 58. Dordrecht: Springer, 2005. Pp. xiii + 293. Cloth, $149.00.Leibniz's metaphysics has long been viewed as one of the more noteworthy systems of idealism in early modern philosophy. At the ground-floor level of his austere ontology, (...) the standard view maintains that the world is not populated by bodies in space and time, but rather by immaterial, mind-like entities: monads. All the rest is a kind of ontological construction from these simple substances. In this book, Pauline Phemister seeks to overturn the idealist reading of Leibniz and to show that "the true immaterial substances in Leibniz's philosophy" are "monads that exist as animated corporeal creatures" (76). What is ontologically basic for Leibniz are not immaterial monads but "living corporeal substances" with "both mental and physical characteristics" (3).If Phemister is right, one wonders what to make of Leibniz's many endorsements of idealism, as, for instance, when he says that "the explanation of all phenomena solely through the perception of monads... with corporeal substances to be rejected, [is] useful for a fundamental investigation of things" (Leibniz to Bartholomew Des Bosses, June [End Page 162] 16, 1712). This programmatic summary is only one of numerous statements from the late period where Leibniz asserts that ultimate reality is composed of immaterial monads. One possible option would be to posit an indecisive vacillation in Leibniz's late philosophy. Rejecting this, Phemister's strategy for dealing with texts such as these—including the "New System," the "Principles of Nature and Grace," and the "Monadology"—is to dismiss them as the rhetorical subterfuge of a Leibniz who is only exoterically, not privately, a Cartesian (15, 163). Leibniz is a public Cartesian in that he "invites comparison of his rational monads with Cartesian minds" by suggesting that the former, like Cartesian minds, are immaterial and incorporeal (13). This is ostensibly only a ruse Leibniz used to ingratiate himself to a Cartesian audience, hiding from them his real view that genuine substances are always corporeal. We are not told why Leibniz would have expected an idealist philosophy that explains mind-body interaction in terms of a pre-established harmony to be well received by Cartesians, but with this hermeneutical principle in hand, Phemister has deftly insulated her criticism from textual refutation.A more pressing concern is Phemister's principle thesis that "the monad is a corporeal substance" (73). Phemister argues that monads are not complete substances unless they comprise not only a soul-like entelechy, but also primary and secondary matter: a monad is not substantially complete "without the subordinate monads that comprise its organic body" (41). What is important to note in this account is that for monads to be complete substances, they must consist of both a "soul-like aspect" and secondary matter, an organic body (133). This organic body is itself an aggregate of other corporeal substances, which are themselves combinations of entelechies and primary and secondary matter (81). The clear consequence of this is that the monad's existence as a complete substance is dependent upon the existence of other substances, namely, those substances that aggregate to form its organic body, the secondary matter that completes the monad as substance. Hence, the existence of complete substances—the only genuine substances—is ontologically derivative. This conclusion flatly contradicts Leibniz's repeated assertions that substances are ontologically basic, not depending for their existence on the existence of other substances, the very cornerstone of Leibniz's metaphysics.This account is also beset by a vicious circularity. For there to be complete substances, there must first be secondary matter, as secondary matter is a constituent of complete substances. As Phemister puts it, "both primary and secondary matter complete the dominant entelechy," making it a genuine substance (71). Without secondary matter, the dominant entelechy does not exist as a substance. But the existence of secondary matter is itself dependent upon the existence of complete substances, for secondary matter just is an aggregate of corporeal substances (84... (shrink)

Leibniz’s mechanistic reduction of colors and other sensible qualities commits him to two theses about our knowledge of those qualities: first, that we can acquire ideas of sensible qualities apart from any direct acquaintance with the qualities themselves; second, that we can acquire distinct (i.e., non-confused) ideas of such qualities through the development of physical-theoretical accounts. According to some commentators, however, Leibniz frequently denies both claims. His views on the subject are muddled and incoherent, they say, both because he is (...) ambivalent about the nature of sensible qualities, and because he gets confused about confusion, losing sight of his own distinction between the confusion proper to perceptions and that proper to ideas. In opposition to this, I argue that the critics have misunderstood Leibniz’s views, which are both consistent over time and coherent. The key to understanding his position is to appreciate what he characterizes as a kind of redundancy in our ideas of sensible qualities, a crucial feature of his view overlooked by the critics.

In 1985 Daniel Garber published his highly intluential paper “Leibniz and the Foundations of Physics: The Middle Years”. In two recent articles, Garber returns to these issues with a new position - that we should perhaps conclude that Leibniz did not have a view concerning the ultimate ontology of substance during his middle years. I discuss the viability of this position and consider some more general methodological issues that arise from this discussion.

Students in 1989 were at pains to distinguish their actions from those taken by students in the Cultural Revolution. Yet there were important similarities. In the present paper, we identify influence on the Democracy Movement from the Cultural Revolution through (1) the expansion and/or widespread familiarization of repertories of collective action available to Chinese activists; (2) precedents for collective action that may have lowered the barriers to action for some while raising them for others; (3) the participation of people at (...) different stages of their lives in both movements; (4) the transformation of the significance of the ideas of democracy and political authority wrought by the Cultural Revolution for many Chinese; (5) the impact of the Cultural Revolution on Chinese intellectuals; (6) the material consequences of the Cultural Revolution which contributed to China's position in the post-Mao era and the specific issues reform and protest sought to confront; (7) the discourse of corruption which provided the 1989 movement with its strongest links between students and ordinary citizens, and which was accentuated in the Cultural Revolution; (8) the affirmation of the value of ordinary life by which students in the 1980s, encouraged by the `literature of the wounded', rebelled against the Puritanism and denigration of `unauthorized' personal relationships that had been characteristic of the Cultural Revolution; (9) the role of the Cultural Revolution as a cautionary tale, shaping the movement itself, inhibiting some older intellectuals from participating, and determining much of how the government viewed and responded to the Democracy Movement; and (10) the embeddedness in different ways of both Cultural Revolution and 1989 protests in an international context.

The development of modern Chinese thought involves an ongoing interaction between internal processes and impacts of foreign ideas. Several intellectual controversies are interwoven into its history and among these one of the more philosophical ones began some 90 years ago, in 1923. In this controversy, supporters of science or scientism and supporters of metaphysics or Confucian tradition debated issues of what both sides referred to as "the view of life." The study of the view of life controversy by (...) Gad C. Isay discusses the positions of the view of life supporters who upheld metaphysics against scientism. It focuses on both the philosophical merit of their views and the relevance of these views to the question of culture in modern China. Considering the sources of the view of life problem in traditional Chinese thought and the discussions that followed after the controversy, it is argued that the view of life question was a central theme in Chinese thought from its beginning. In this respect, modern discussions of this problem indicate continuity with the past. However, these discussions demonstrate too, the dynamics of changing conceptions regarding the context of human relationships that are related directly to the meeting with the West. Isay's study traces the development of these discussions from their beginning up to our days giving a comprehensive survey of the philosophy of the view of life in modern Chinese thought. (shrink)

In this paper I challenge the common view that early in his career (1679-1695) Leibniz held that space and time are well-founded phenomena, entities on an ontological par with bodies and their properties. I argue that the evidence Leibniz ever held that space and time are well-founded phenomena is extremely weak and that there is a great deal of evidence for thinking that in the 1680s he held a position much like the one scholars rightly attribute to him in (...) his mature period, namely, that space and time are merely orders of existence and as such are purely abstract and occupy an ontological realm distinct from that of well-founded phenomena. In the course of arguing for this interpretation, I offer an account of the nature of Leibnizian phenomena which allows Leibniz to hold the view that space and time are phenomena, while at the same time thinking of them as abstract, ideal orders of existence.

We reckon again these conception at the grounds of his later philosophy of nature. But now we have to follow Leibniz demostrating how universal and infinite variations flow from its topological conditions. (shrink)

Summary In some very interesting recent work, Peter Fenves has sought to trace G. W. Leibniz's views on human diversity back to the philosopher's core philosophical concerns, in particular to his metaphysical picture of the world as consisting in causally unconnected substances, monads, that are ‘windowless’, ‘worlds apart’. In this article I argue by contrast that Leibniz's anthropological views develop quite independently of his core metaphysics, and are rooted instead in his significant work as a historian and genealogist. In this (...) connection, he develops a conception of race as a ‘series of generations’, and of genealogy as ‘the explication of this series’, that will in turn ground much of his thought about not just human groups, but about living kinds in general. These conceptions, moreover, offer significant new insight into Leibniz's position with respect to the philosophical problem of the ontological status of species. (shrink)

Davidson suggests that metaphor is a pragmatic (not a semantic) phenomenon; on his view, metaphor is a perlocutionary effect prompts its audience to see one thing as another. Davidson rightly attacks speaker-intentionalism as the source of metaphorical meaning, but settles for an account that depends on audience intentions. A better approach would undermine intentionalism per se, replacing it with a social practice analysis based on patterns of extending the metaphor. This paper shows why Davidson’s perceptual model fails to stave (...) off semantic analysis, and argues that the professed virtues of Davidson's position are more readily found in an account that focuses on the nature of metaphorical interpretation.

The main topic of the following dissertation is Kant's Third Analogy of Experience, which asserts that one must posit a bond of mutual interaction in order to judge that two substances exist simultaneously. Part One considers the Third Analogy proper and reconstructs two plausible arguments for its main claim. Contrary to the view of most commentators , Kant is entitled to a strong causal notion of mutual interaction. Part Two considers the historical debate between proponents of Pre-established Harmony, Occasionalism, (...) and Physical Influx and how the Third Analogy can be seen as Kant's most developed version of Physical Influx. Thus, we see that Kant's concern with causality is not exhausted by his reply to Hume in the Second Analogy of Experience. For Kant is clearly concerned to attack the rationalist tradition by criticizing Leibniz's and Wolff's Pre-established Harmony, on the one hand, and the Cartesians' and Malebranche's Occasionalism, on the other hand. Part Three considers the argumentative structure of Kant's Metaphysische Anfangsgrunde der Naturwissenschaft and how the Third Analogy relates to this work. Contrary to what one might expect, the MAdN does not proceed by first presupposing a Principle from the first Critique and then substituting in the concept of matter. Rather, its substantial results are obtained through an extended transcendental argument showing how we can have experience of objects of outer sense . Further, we see how the abstract notion of mutual interaction involved in the Third Analogy becomes more specific in the MAdN since two of the most important features of its central notion of matter, namely the capacities of filling a space and of communicating motion, require attractive and repulsive forces and action and reaction, both instances of mutual interaction. These three lines of argument establish that the Third Analogy of Experience both constitutes a crucial part of Kant's position and presents a philosophically plausible view. (shrink)

The article reconstructs a brief controversy between H. More, G. W. Leibniz and J. G. Wachter about the Kabbalah, or what they called ‘the philosophy of the Hebrews’. I study in particular the status of the proposition ‘nothing comes out of nothing’ in their exchanges - a proposition they all agreed was a fundamental kabbalist axiom while having differing views as to the prospects of reconciling that position with Christianity. I show how Wachter’s curious Kabbalistico-Spinozism provided the stage for an (...) indirect philosophical encounter between Leibniz and More that highlights not only their respective positions on the Kabbalah, but also suggests some important philosophical agreement between them regarding divine transcendence and the nature of creation.

Rare earth elements have become increasingly important because of their relative scarcity and worldwide increasing demand, as well as China’s quasi-monopoly of this market. REEs are virtually not substitutable, and they are essential for a variety of high-tech products and modern key technologies. This has raised serious concerns that China will misuse its dominant position to set export quotas in order to maximize its own profits at the expense of other rare earth user industries. In fact, export restrictions (...) on REEs were the catalyst for the U.S. to lodge a formal complaint against China in 2012 at the World Trade Organization. This paper analyzes possible wealth transfer effects by focusing on export quota announcements by China, and the share price reactions of Chinese REE suppliers, the U.S. REE users, and the rest of the world REE refiners. Overall, we find limited support for the view of a wealth transfer in connection with MOFCOM announcements only when disentangling events prior to and post the initiation of the WTO trial, consistent with the trial triggering changes to China’s REE policy and recent announcement to abolish quotas. We do find, however, that extreme REE price movements have a first-order effect on all companies in the REE industry consistent with recent market trends to enable hedging against REE price volatility.

Leibniz argued that in natural world, only intra-substantial or immanent causation is possible— the causation that takes place within an individual, when an individual brings about a change in itself. In this dissertation, I address issues arising from Leibniz’s arguments against the rival view that posits a world of causally interacting substances and issues pertaining to Leibniz’s own positive metaphysics of immanent causation and change. -/- Chapter 1 is devoted to stage setting for the remainder of the dissertation. (...) I first offer a historically informed overview of efficient causation and change before introducing Leibniz’s novel views, including his criticisms of competing accounts and his own positive account. After presenting a detailed roadmap of my project, I articulate the idealistic interpretation of Leibniz assumed in this dissertation, where the only genuine substances are simple monads. Finally, I articulate the methodological approaches I employ. -/- In Chapters 2 and 3, I reconstruct and assess Leibniz’s most frequent argument against transeunt causation (the causation that occurs when a substance produces a property in a numerically distinct substance), what I call the “Transference Argument.” Leibniz argued that a created substance’s causing an accident in a numerically distinct substance is possible only if the agent transfers the accident from itself to the patient, where upon transference the agent no longer possesses the accident it transferred. Call the transeunt causal requirement that the agent transfer the accident produced from itself to the patient the “Transference Condition.” -/- Chapter 2 is devoted to two problems with Leibniz’s transference condition. First, Leibniz stated the transference condition throughout his career, but offered little argument for it. Second, God is a transeunt cause in Leibniz’s metaphysics yet God’s causation does not consist in transference. Thus, Leibniz needs a principled way to require transference for creaturely causation while denying that divine transeunt causation consists in transference. Finally, I close off chapter 2 by drawing attention to an important weakness with the transference condition that has not yet been recognized by Leibniz scholars. -/- In Chapter 3, I argue that there is nothing in Leibniz’s ontology that could be transferred from the cause to the recipient of the effect. I first argue that Leibniz’s ontology consists of simple non-corporeal substances and their modifications. Second, I present and articulate a number of important theses Leibniz affirmed about substances and their modifications, which entail that neither could be transferred. I also show that most of these theses were not unique to Leibniz, but were in fact widely endorsed by his predecessors who defended the possibility of creaturely transeunt causation. -/- In chapter 4, I continue the study of the nature of Leibnizian accidents, shifting the focus from their role in Leibniz’s critique of creaturely transeunt causation to their positive role in change and as causal relata, where such accidents are the effects of immanent causation. I shall argue that Leibniz’s thesis that accidents are modifications or limitations allowed him to posit mereologically simple substance that have a multitude of accidents at a time and change accidents over time. -/- In Chapter 5, I address an issue that has divided Leibniz scholars concerning the precise relata in Leibnizian immanent efficient causation. In many passages, Leibniz writes as if it is the substance or individual itself that efficiently causes its later properties or accidents. Call this the “Efficacious-substance” account. The efficacious-substance account is difficult to reconcile with Leibniz’s requirements that change be intelligible and deterministic. In plenty of other passages, he writes as if it is the substances earlier properties or accidents that cause its later accidents. Call this the “Efficacious-accident” account. The efficacious-accident account explains how change is intelligible and deterministic but it faces a “plurality of agents” objection. If a substance’s accidents are the efficient causes of later accidents, then prima facie there is a plurality of efficient causal agents in a substance. This view is incompatible with Leibniz’s requirement that substances be simple, unified entities. -/- Drawing upon a Scholastic distinction made between two kinds of efficient causes— principle quod efficient causes and principle quo efficient causes, I shall argue that for Leibniz, substances are principle quod efficient causes and their appetitions are principle quo efficient causes. This interpretation combines the strengths of the Efficacious-substance and Efficacious-accident accounts while overcoming their weaknesses. There is just one causal agent, the substance, but change is both intelligible and deterministic because as what an agent produces is explained by its appetitions. (shrink)

Leibniz was interested in China throughout his life, and he admired its culture. Originally, his interests revolved around Chinese characters, but widened when meeting the Jesuit China missionary P. Grimaldi in Rome 1689. From that time on, Leibniz pursued the project of a knowledge exchange between both sides of the world. He was convinced that Europe and China were on the same cultural level, while diverging over advances in distinct fields. In his view, Europe was more (...) advanced in theoretical areas, such as logic, mathematics, geometry, physics, mathematical astronomy, and theory of natural religion, while China was superior in empirical disciplines, such as in observational astronomy, medicine, historiography, and moral philosophy, which he understood as natural (i.e. rational) theology. This project of knowledge exchange presupposed the recognition of Chinese culture. In this sense, Leibniz strongly supported the Jesuit position, according to which the rites of ancestral worship and reverence of Confucius are riti politici rather than literal expressions of religious faith. Leibniz’s main objection to the Pope’s negative assessment of Chinese rites was that one cannot settle the so-called Rites Controversy as long as one fails to interpret adequately Chinese culture and Confucian thought in particular.

The core idea of the ontological proof is to show that the concept of existence is somehow contained in the concept of God, and that therefore God’s existence can be logically derived—without any further assumptions about the external world—from the very idea, or definition, of God. Now, G.W. Leibniz has argued repeatedly that the traditional versions of the ontological proof are not fully conclusive, because they rest on the tacit assumption that the concept of God is possible, i.e. free from (...) contradiction. A complete proof will rather have to consist of two parts. First, a proof of premiseGod is possible. Second, a demonstration of the “remarkable proposition”If God is possible, then God exists. The present contribution investigates an interesting paper in which Leibniz tries to prove proposition. It will be argued that the underlying idea of God as a necessary being has to be interpreted with the help of a distinguished predicate letter ‘E’ as follows:\\). Proposition which Leibniz considered as “the best fruit of the entire logic” can then be formalized as follows:\) \rightarrow \, E)\). At first sight, Leibniz’s proof appears to be formally correct; but a closer examination reveals an ambiguity in his use of the modal notions. According to, the possibility of the necessary being has to be understood in the sense of something which possibly exists. However, in other places of his proof, Leibniz interprets the assumption that the necessary being is impossible in the diverging sense of something which involves a contradiction. Furthermore, Leibniz believes that an »impossible thing«, y, is such that contradictory propositions like \\) and \\) might both be true of y. It will be argued that the latter assumption is incompatible with Leibniz’s general views about logic and that the crucial proof is better reinterpreted as dealing with the necessity, possibility, and impossibility of concepts rather than of objects. In this case, the counterpart of turns out to be a theorem of Leibniz’s second order logic of concepts; but in order to obtain a full demonstration of the existence of God, the counterpart of, i.e. the self-consistency of the concept of a necessary being, remains to be proven.

In Immanuel Kant's pre-critical writings as well as in his main critical work, the Critique of Pure Reason, one finds a whole battery of fierce attacks on core doctrines of Leibnizian philosophy, e.g., the monadology, the principle of the identity of indiscernibles, the principle of sufficient reason, the doctrine of the pre-established harmony, or the relationalist theory of space and time. It is tempting to read Kant's philosophical development as a gradual emancipation from his Leibnizian upbringing, culminating in a thorough (...) rejection of Leibnizian philosophy as a paradigm case of the kind of dogmatic metaphysics that Kant wants to overcome with his critical philosophy. But in addition to the familiar texts in which Kant attacks the Leibnizians there are several curious, less well-discussed passages in which Kant speaks in highly approving terms of Leibniz. In these passages Kant self-avowedly defends Leibniz against his Leibniz-Wolffian followers who, according to Kant, have seriously misunderstood Leibniz's original position. Kant maintains that a correct reading of Leibniz reveals that his own and Leibniz's views are in fact very close, and that with regard to many issues that are central to transcendental idealism Leibniz had already tried to say what Kant then made explicit in his critical work. The project of this essay is to lay the foundation for the examination of an unorthodox reading of the relation between Leibnizian metaphysics and Kantian transcendental idealism, according to which Kant's critical philosophy can correctly be described as the "true apology of Leibniz", as Kant claims, while Kant's sharply critical objections in the pre-critical works and in the Critique of Pure Reason for the most part don't apply to Leibniz's original theory but to Leibniz-Wolffian school-philosophy. The present essay provides the necessary groundwork for the examination of this unorthodox reading by showing that, and to what extent, these Kantian objections do not apply to Leibniz himself, and by arguing that Kant's reading of certain central Leibnizian doctrines in which Leibnizian metaphysics is represented as a forerunner of transcendental idealism is indeed defensible.

During the late Ming and early Qing period, Jesuit missionaries introduced European science into China, and thereby profoundly influenced the later development of Chinese astronomy. Not only did European astronomy become the official system of the Qing dynasty, but the traditional way to ‘attain up above’ by connecting the study of astronomy and Yi learning gradually fell into disuse. However, the astronomers in this period expressed different views on these two processes. As one of the most important early Qing (...) astronomers, Xue Fengzuo’s case presents a distinctive and important example. Firstly, under the influences of both Chinese tradition and European science, Xue Fengzuo rebuilt the way to ‘attain up above’ based on his three-fold ‘calendrical learning’, i.e. calendrical astronomy, astrology and related pragmatic applications, through which he could realize the highest Confucian ideal. Secondly, he integrated Chinese and Western knowledge for all three aspects of his ‘calendrical learning’, instead of ceding the dominant position to Western methods. From Xue Fengzuo’s example, many of the complex effects of the encounter between different cultures and the process of knowledge transfer can be revealed. (shrink)
