According to the received view, Hume is a much more rigorous and consistent concept-empiricist than Locke. Hume is supposed to have taken as a starting point Locke's meaning-empiricism, and worked out its full radical implications. Locke, by way of contrast, cowered from drawing his theory's strange consequences. The received view about Locke's and Hume's concept-empiricism is mistaken, I shall argue. Hume may be more uncompromising (although he too falters), but he is not more rigorous than Locke. It is not because (...) of (intellectual) timidity that Locke does not draw Hume's conclusions from his empiricism. It is, rather, because of his much sounder method. (shrink)

This article describes and defends an inclusive anti-canonical approach to the study of the history of philosophy. Its proposal, based on an analysis of the nature of the history of philosophy and the value of engaging in the practice, is this: The history of philosophy is the history of rationally justified, systematic answers to philosophical questions; studying this subject is both intrinsically and instrumentally valuable; these benefits do not derive from the imposition of a canon—indeed, there should be no canon; (...) the absence of a canon leaves room for a thousand courses on a thousand different topics with a thousand different narrative structures; but a good syllabus should be relevantly diverse in a way that fits the thematic arc of the course; and this prescription for the discipline is inclusive, in ways that can only strengthen and enliven it for future generations.

Leibniz has almost universally been represented as denying that created substances, including human minds and the souls of animals, can causally interact either with one another or with bodies. Yet he frequently claims that such substances are capable of interacting in the special sense of what he calls 'ideal' interaction. In order to reconcile these claims with their favored interpretation, proponents of the traditional reading often suppose that ideal action is not in fact a genuine form of causation but instead (...) a merely apparent influence which serves to 'save the appearances.' I argue that this traditional reading distorts Leibniz's thought and that he actually considers ideal action a genuine (though non-standard) form of causation. (shrink)

Descartes is widely portrayed as the arch proponent of “the epistemological transparency of thought” (or simply, “Transparency”). The most promising version of this view—Transparency-through-Introspection—says that introspecting (i.e., inwardly attending to) a thought guarantees certain knowledge of that thought. But Descartes rejects this view and provides numerous counterexamples to it. I argue that, instead, Descartes’s theory of self-knowledge is just an application of his general theory of knowledge. According to his general theory, certain knowledge is acquired only through clear and distinct (...) intellection. Thus, in his view, certain knowledge of one’s thoughts is acquired only through clear and distinct intellection of one’s thoughts. Introspection is a form of intellection and it can be clear and distinct. Ordinarily, however, introspection isn’t clear and distinct but is instead confused with dubitable perceptions of bodies. To make introspection clear and distinct, we need to “sharply separate” it from all perceptions of bodies by doubting all perceptions of bodies. Without such radical doubt, introspection remains confused and we lack certain knowledge not just of the specific features of our thoughts, but even of the minimal claim that a thought exists. Far from being the high priest of Transparency, Descartes is radically opposed to it. (shrink)

Philosophers today have largely given up on the project of categorizing being. Aristotle’s ten categories now strike us as quaint, and no attempt to improve on that effort meets with much interest. Still, no one supposes that reality is smoothly distributed over space. The world at large comes in chunks, and there remains a widespread intuition, even among philosophers, that some of these chunks have a special sort of unity and persistence. These, we tend to suppose, are most truly agents (...) and subjects, and are what exist in the most proper sense of the term. We believe, in other words, in substances. (shrink)

In his groundbreaking work of 1969, Spinoza's Metaphysics: An Essay in Interpretation, Edwin Curley attacked the traditional understanding of the substance-mode relation in Spinoza, according to which modes inhere in substance. Curley argued that such an interpretation generates insurmountable problems, as had already been claimed by Pierre Bayle in his famous Dictionary entry on Spinoza. Instead of having modes inhere in substance Curley suggested that the modes’ dependence upon substance should be interpreted in terms of (efficient) causation, i.e., as committing (...) Spinoza to nothing over and above the claim that substance is the (efficient) cause of the modes. These bold and fascinating claims generated one of the most important scholarly controversies in Spinoza scholarship of the past thirty-five years. In this paper I argue against Curley’s interpretation and attempt to reestablish the traditional understanding of Spinozistic modes as inhering in God and as predicated of God. I also criticize Curley’s philosophical motivation for suggesting this interpretation. In order to show that, for Spinoza, modes are predicated of - and inhere in - substance, I will proceed in the following manner. First, I will summarize Curley’s arguments against substance-mode inherence and present his alternative interpretation of the substance-mode relation. I will then present what I consider to be the most compelling arguments against Curley’s interpretation. Some of these arguments have already been suggested in the literature of the past thirty years (and by Bayle); however, as far as I know, most of the arguments I will be making are new. In the subsequent section I will respond to objections that Curley and Bayle advance against Spinoza’s view of God as the substratum in which all things inhere. Finally, I will address whether Spinozistic modes are predicated of (and not only inhere in) substance, and whether Spinoza considered modes to be particular properties (or “tropes,” in the jargon of contemporary metaphysics). Since Bayle’s claims will be used both in support of and against Curley’s interpretation, it would be appropriate to say a few introductory words on Bayle’s stance. In his Spinoza entry, Bayle criticizes Spinoza’s claim that all things are modes of God, claiming that it “is the most monstrous hypothesis that could be imagined, the most absurd, and the most diametrically opposed to the most evident notions of our mind.” Bayle, however, has no doubt that when Spinoza claims that all things are modes of God, Spinoza means that all things inhere in God. Curley embraces Bayle’s arguments against Spinoza, but uses them in order to claim that we should not ascribe to Spinoza a view which is allegedly shown by Bayle to be absurd. What we should do, Curley argues, is to reinterpret the substance-mode relation as a relation of causal dependence, which would set Spinoza free from Bayle’s hook. Interestingly, as we shall soon see, Bayle himself discusses and rejects a very similar revisionary interpretation of the substance-mode relation. (shrink)

Leibniz, it seems, wishes to reduce statements involving relations or extrinsic denominations to ones solely in terms of individual accidents or, respectively, intrinsic denominations. His reasons for this appear to be that relations are merely mental things (since they cannot be individual accidents) and that extrinsic denominations do not represent substances as they are on their own. Three interpretations of Leibniz''s reductionism may be distinguished: First, he allowed only monadic predicates in reducing statements (hard reductionism); second, he allowed also `implicitly (...) relational predicates'' such as `loves somebody'' (soft reductionism); third, he allowed also `explicitly relational predicates'' such as `loves Helen'' (nonreductionism). Hard reductionism is problematic with respect to Leibniz''s doctrines of universal expression and incompossibility (among other things). Nonreductionism, in turn, faces insurmountable problems with Leibniz''s doctrine of self-sufficiency and internal identification of substances, as well as with that of individual accidents. The remaining option, soft reductionism, standing between the other two interpretations, arguably avoids at least some of their problems. (shrink)

According Leibniz's thesis of universal expression, each substance expresses the whole world, i.e. all other substances, or, as Leibniz frequently states, from any given complete individual notion (which includes, in internal terms, everything truly attributable to a substance) one can "deduce" or "infer" all truths about the whole world. On the other hand, in Leibniz's view each (created) substance is internally individuated, self-sufficient and independent of other (created) substances. What may be called Leibniz's expression problem is, how to reconcile these (...) views with each other, that is, how a substance that expresses the whole world, even in the sense that the whole world can be "inferred" from its complete individual notion, can be self-sufficient and internally individuated. The purpose of this paper is to give an exact account of this tricky problem of universal expression, an account that retains substances' self-sufficiency under the constraint that all truths about the whole world are to be obtained from complete individual notions. It will also be shown how the explication of universal expression to be given accounts for Leibniz's thesis of universal change, i.e. the view that any change in any substance is reflected as a real, internal change in each and every other substance.

The paper discusses Leibniz's theory of denominations, expression, and individual notions, the central claim being that the key to many of Leibniz's fundamental theses is to consider his argument, starting from his predicate-in-subject account of truth (that in a true statement the notion of the predicate is contained in that of the subject), against purely extrinsic denominations: this argument shows why there is an internal foundation for all denominations, why everything in the world is interconnected, why each substance expresses all (...) the others, and why every change in the world is reflected as a real, internal change in every substance.

This paper provides support for the unorthodox view that Hume’s simple ideas are most fruitfully understood as theoretical posits by showing that adopting this interpretation solves a lingering interpretive difficulty, the missing shade of blue. The missing shade of blue is thought to pose a serious challenge to the legitimacy of Hume’s copy principle. Thinking of Humean simple ideas as theoretical posits reveals a dialectical mismatch between Hume and his envisioned reader that, once understood, makes it clear that the case (...) holds little sway against the copy principle. The solution developed and defended has some significant advantages over extant solutions. (shrink)

In this paper, I argue that Spinoza's claim at E1P15 that “Whatever is, is in God, and nothing can be or be conceived without God” remains exegetically troubling. Briefly noting some unresolved difficulties with the two dominant interpretations of Spinoza's account of the relationship between finite modes and God (these being the inherence and causal dependence readings), I move to claim that there is a third, neglected reading available which deserves consideration. I argue that, perhaps surprisingly, Althusser's notion of “structural (...) causality,” putatively derived from Spinoza himself, can be used to construct this reading. Althusser's original notion of “structural causality” is explained and clarified further, its advantages outlined over competing readings of Spinoza, and exegetical evidence for its applicability to Spinoza is then produced.

En este artículo desafío la aseveración sostenida por Peden y Brandt de que la filosofía de Spinoza es esencialmente incompatible con ciertas posiciones fundamentales de la fenomenología. Contra eso, sostengo que lo que Spinoza llama la imaginación se asemeja a la percepción en la fenomenología de Merleau-Ponty. Se justifica esa tesis a partir de una lectura semiótico-hermenéutica de la teoría de la imaginación spinozista, la cual permite ver ciertas semejanzas entre las epistemologías de percepción entre estos respectivos filósofos. A la (...) vez, al destacar las convergencias entre Spinoza y Merleau-Ponty, se ponen de relieve las divergencias entre el cartesianismo y la fenomenología, y surge la posibilidad de una lectura novedosa de la fenomenología desde una perspectiva spinozista.

Contrary to a popular reading of his modal epistemology, Berkeley does not hold that inconceivability entails impossibility, and he cannot therefore argue the impossibility of mind-independent matter by appealing to facts about what we cannot conceive. Berkeley is explicit about this constraint on his metaphysical argumentation, and, I argue, does respect it in practice. Popular mythology about the ‘master argument’ notwithstanding, the only passages in which he might plausibly seem to employ the principle that inconceivability entails impossibility are those that (...) argue for the inseparability of primary from secondary qualities. However, an alternative reading of these texts is available that is both consistent with Berkeley's express modal epistemology and credible in its own right. (shrink)

Leibniz argues that Cartesian extension lacks the unity required to be a substance. A key premise of Leibniz’s argument is that matter is a collection or aggregation. I consider an objection to this premise raised by Leibniz’s correspondent Burchard de Volder and consider a variety of ways that Leibniz might be able to respond to De Volder’s objection. I argue that it is not easy for Leibniz to provide a dialectically relevant response and, further, that the difficulty arises from Leibniz’s (...) commitment to part-whole priority in the case of material wholes, a commitment not shared by De Volder. One major implication is that Leibniz relies on a bottom-up conception of material things, which makes his argument vulnerable to objections stemming from certain types of monist positions. (shrink)

In his recent survey of the “dialectic of creation” in seventeenth-century philosophy, Thomas Lennon has suggested that Descartes’s assumptions about causality encourage a kind of “pantheistic emanationism”. Lennon notes that Descartes regularly invokes the principle that there is nothing in the effect which was not previously present, either formally or eminently, in the cause. Descartes also believes that God is the continuous, total, and efficient cause of everything. From these assumptions it should follow that everything that exists in the created (...) world is previously present in God. Indeed, Descartes embraces the emanationist doctrine explicitly when, at the end of his replies to the Second Set of Objections, he arranges the arguments of the Meditations in “geometrical fashion.” The demonstration of Proposition III includes a sub-proof of the proposition that “he who preserves me has within himself, either formally or eminently, whatever is in me”. Since God preserves the entire universe, it follows that everything is in him, either formally or eminently. While far from the radical Spinozistic view that God and the world are identical, the notion that everything in creation is also in God would seem to have its own unwelcome theological consequences, at least from a Cartesian point of view. In particular, it implies that extension, and hence divisibility, are in God. But, as Descartes himself cautions, “being divisible is an imperfection” and so completely foreign to God. (shrink)

RESUMEN: La teoría causal formulada por Kripke y Putnam es la teoría semántica dominante de los términos de género natural y, en especial, de los términos de sustancia. La teoría semántica de los términos de sustancia de Locke ha sido, supuestamente, refutada por aquélla. Según Putnam, la teoría de Locke ha pasado por alto dos importantes contribuciones a la semántica, y principalmente a la referencia, de los términos de sustancia, a saber, la contribución de la sociedad y la del entorno. (...) El objetivo de este artículo es argüir que la teoría de Locke puede incorporar la primera contribución y que alguien que en principio sostuviese una teoría como la de Locke podría verse llevado a aceptar también la segunda contribución.ABSTRACT: The causal theory put forward by Kripke and Putnam is the dominant semantic theory of natural kind terms and especially of substance terms. Locke’s semantic theory of substance terms has supposedly been rebutted by it. Locke’s theory has, according to Putnam, overlooked two significant contributions to the semantics, and mainly to the reference, of substance terms, namely, the contribution of the society and that of the environment. This paper aims to argue that Locke’s theory is able to embrace the first contribution and that someone who initially held a theory like Locke’s could be led to accept also the second one. (shrink)

In his brief treatment of memory, Hume characterizes memory using two kinds of criteria: ideas’ phenomenal character and their correspondence to the past experiences from which they derived. These criteria have seemed so perplexing to interpreters, both individually and jointly, that Hume’s account of memory is commonly considered one of the weakest parts of his philosophical system. This paper defends Hume’s criteria by showing that they achieve two theoretical aims: a scientific classification of ideas and a definition of ‘memory.’ In (...) particular, I argue that Hume’s definition of ‘memory’ is cogent in light of Putnamian considerations about definitions.

This essay gives a new interpretation of Hume's second thoughts about minds in the Appendix, based on a new interpretation of his view of composition. In Book 1 of the Treatise, Hume argued that, as far as we can conceive it, a mind is a whole composed by all its perceptions. But—this essay argues—he also held that several perceptions form a whole only if the mind to which they belong supplies a “connexion” among them. In order to do so, it (...) must contain a further perception or perceptions. But when the perceptions in question are all of those belonging to a given mind—as in the section “Of personal identity” and the Appendix—there cannot be a further perception in that mind, and so those perceptions do not form a whole. Hence, Hume's views were inconsistent. This essay argues that, unlike most others, this interpretation explains his retreat to skepticism in the Appendix. (shrink)

John Locke holds that matter is solid, the soul thinks, and for all we know the soul may be a material substance divinely endowed with a power to think. Though he openly admits to nothing stronger than the bare possibility of thinking matter, Locke grants that what thinks in us occupies a definite spatial location to the exclusion of other souls. Solidity is the quality that prevents other things from occupying a spatial location. Locke’s general criterion for identity is spatiotemporal (...) exclusion of other things of the same kind. To meet these conditions for identity, souls must be solid. Although Locke refuses to declare that souls really are material things, taking the solidity of souls to be a condition for their identity is consistent with the following of Locke’s other important commitments: nominalism about the essences by which substances are classified, agnosticism about the underlying reality of what supports such “nominal essences,” and the identity of persons is distinct from the identity of any substance. Locke ignores the implication that souls are solid because the solidity of souls is irrelevant to those three aims. Nevertheless he could allow for the solidity of souls without giving up on any of his other important and explicitly held commitments. There is therefore no need for Locke’s commentators to refrain from employing solidity in their accounts of Locke’s general criterion for identity from fear of attributing to Locke the position that souls would be solid.

In his discussion of our idea of time in the Treatise, Hume makes the perplexing claim that unchanging objects cannot be said to endure. While Hume is targeting the Newtonian conception of absolute time, it is not at all clear how his denial that unchanging objects are in time fits with this target. Moreover, Hume diagnoses our belief that unchanging objects endure as the product of a psychological fiction, but his account of this fiction is also riddled with puzzling claims (...) about our experience of unchanging objects. In this paper, we argue that Hume’s claims are a lot less baffling and indeed, much more sophisticated than they appear. We do so by considering his arguments as a response to Locke’s specific approach to the concept of absolute time. (shrink)

What motivates the benevolent or charitable agent is regard for another’s good or well-being, but talk about regard for others’ good or well- being is simply talk about benevolence or charity in different terms. Yet Hume clearly holds that the regard for another’s good is a motive to produce benevolent acts that is distinct from a sense of their benevolence. So what is the difference? ‘Well’, one might say, ‘intuitively, rights are very different from wellbeing.’ Yes indeed. And that, I (...) shall contend, is Hume’s point. My general contention is that Hume’s discussion of justice is in fact an attack on that concept of rights we think of as having motivated the American and French revolutions, a concept that is still (deplorably in my view) prevalent. I think the very fact that it is so prevalent and so sanctified by its position in the American Constitution has blinded most readers to the power and plausibility of Hume’s attack, which I shall try to defend.

Metaphysics and ethics are two distinct fields in academic philosophy. The object of metaphysics is what is, while the object of ethics is what ought to be. Necessitarianism is a modal doctrine that appears to obliterate this neat distinction. For it is commonly assumed that ought (at least under normal circumstances) implies can. But if necessitarianism is true then I can only do what I actually do. Hence what I ought to do becomes limited to what I in fact do. (...) This is one widespread way of construing the danger that necessitarianism poses for ethics. There is, however, another way in which this collapse of what is with what ought to be can be construed. One could think of what is as already being what ought to be, of the two being one. On this picture, everything that is, is already valuable. In this thesis I explore the theory that being is intrinsically valuable. I do so by investigating the philosophy of perfection present in the works of the early modern rationalist Spinoza. For in his philosophy of perfection, I argue, we find being and value to be perfectly aligned. Hence, my reading challenges a widespread interpretation, according to which (ontological) perfection is divested of normativity in Spinozism. The position that all being is intrinsically valuable since it is perfect may be thought to be incompatible with human perfectionism. For what room can there be for human progress toward an ideal of perfection if all that exists, is necessarily perfect? The goal of the thesis is to respond to this question by providing a systematic interpretation of the metaphysics of human perfectibility in Spinoza’s philosophy. In order to achieve this goal, I undertake two tasks. First, I examine Spinoza’s multi-faceted philosophy of perfection. I distinguish between ontological and teleological perfection. Moreover, I argue that since Spinoza maintains that everything is perfect to the extent that it is, perfection shoulders the role of a transcendental within his system. In order to highlight the normative significance of transcendental perfection, I compare Spinoza’s thought with the transcendental theory of the good in Thomas Aquinas. In addition, I distinguish between ontological and speculative perfection. Speculative perfection is conscious awareness of ontological perfection. Second, I show how infinity plays an essential role in Spinoza’s ethics by indicating how we, by availing ourselves of this notion, are able to acquire a perspective on reality from which its ontological perfection may be discovered. On this basis, I am able to demonstrate the (relatively understudied) ethical and soteriological importance of Spinoza’s conception of infinity. I argue that it is because (a) Spinoza’s ideal of human perfection is speculative, and because (b) one will be able to establish the (ontological) perfection of things by deducing it from the divine essence only when one considers this essence absolutely infinite, that (c) the absolute infinity of the divine essence plays a significant role in Spinoza’s account of human perfection as consisting in conscious awareness of the value of all being.

For Locke, an idea is ‘the immediate object of perception, thought, or understanding’ (§8).1 Perhaps this is something like a concept: he goes on to give examples of white, cold, and round, which look like they have some representational content. What do these ideas represent? Locke defines a quality: ‘the power to produce any idea in our mind, I call quality of the subject wherein that power is’ (§8). The natural thought is that these ideas represent some quality of the (...) object, which quality just is the power that the object has to produce that idea in us. Though the idea is in us, the power or quality is clearly in the object. Sometimes, it is true, we speak loosely and refer to the quality of the object by the same name that we use to refer to the idea in us, and talk of white being in the object, for example. Locke cautions that when we speak like this, we should ‘be understood to mean those qualities in the objects which produce them [the ideas] in us’ (§8). (shrink)

Locke’s theory of consciousness is often appropriated as a forerunner of present-day Higher-Order Perception (HOP) theories, but not much is said about it beyond that. We offer an interpretation of Locke’s account of consciousness that portrays it as crucially different from current-day HOP theory, both in detail and in spirit. In this paper, it is argued that there are good historical and philosophical reasons to attribute to Locke the view not that conscious states are accompanied by higher-order perceptions, but rather (...) that conscious states constitute perceptions of themselves.
