Alexander X. Douglas situates Spinoza's philosophy in its immediate historical context, and argues that much of his work was conceived with the aim of rebutting the claims of his contemporaries. In contrast to them, Spinoza argued that philosophy reveals the true nature of God, and reinterpreted the concept of God in profound and radical ways.

How did the relations between philosophy and science evolve during the 17th and the 18th century? This book analyzes this issue by considering the history of Cartesianism in Dutch universities, as well as its legacy in the 18th century. It takes into account the ways in which the disciplines of logic and metaphysics became functional to the justification and reflection on the conceptual premises and the methods of natural philosophy, changing their traditional roles as art of reasoning and as (...) science of being. This transformation took place as a result of two factors. First, logic and metaphysics were used to grant the status of indubitable knowledge of natural philosophy. Second, the debates internal to Cartesianism, as well as the emergence of alternative philosophical world-views progressively deprived such disciplines of their foundational function, and they started to become forms of reflection over given scientific practices, either Cartesian, experimental, or Newtonian.

Theo Verbeek provides the first book-length examination of the initial reception of Descartes’s written works. Drawing on his research of primary materials written in Dutch and Latin and found in libraries all over Europe, even including the Soviet Union, Theo Verbeek opens a period of Descartes’s life and of the development of Cartesian philosophy that has been virtually closed since Descartes’s death. Verbeek’s aim is to provide as complete a picture as possible of the discussions that accompanied the introduction (...) of Descartes’s philosophy into Dutch universities, especially those in Utrecht and Leiden, and to analyze some of the major problems that philosophy raised in the eyes of Aristotelian philosophers and orthodox theologians. The period covered extends from 1637, the year in which Descartes published his _Discours de la Méthode, _until his death in 1650. Verbeek demonstrates how Cartesian philosophy moved successfully into the schools and universities of Holland and how this resulted in a real evolution of Descartes’s thought beyond the somewhat dogmatic position of Descartes himself. Verbeek further argues that this progression was an essential step in the universal propagation of Cartesian philosophy throughout Europe during the second half of the seventeenth century. As he details the disputes between Cartesians and anti-Cartesians in Holland, Verbeek shows how the questions raised were related on the one hand to religious conflicts between the Remonstrants and the Orthodox Calvinists and on the other hand to political conflicts between more liberal factions fighting for the union of church and state to enhance religious control of society in general. Contending that Descartes and Cartesian philosophy were central to the development of the modern Dutch state, Verbeek illuminates the role they played in Dutch political, religious, and intellectual life.

The fourth chapter analyses the establishment of Cartesianism at the University of Leiden in 1650s and 1660s. This was carried out by De Raey, who provided a defence and teaching of Descartes’s physics in his Clavis philosophiae naturalis (1654), although not based on Descartes’s metaphysics: physical principles, indeed, are presented by De Raey as self-evident truths, and consistent with Aristotle’s theory of scientia or universal and necessary knowledge. This was not the only peculiar characteristic of Leiden Cartesianism, as De Raey (...) also provided a differentiation between philosophical and practical knowledge (including medicine and revealed theology), as these are based on different sources of knowledge, namely, intellect and sensory experience. In the hands of Christopher Wittich, the separation thesis became the standard in conceiving the place of Cartesianism in the university, which was confined to natural philosophy in 1650s and strictly secluded from revealed theology. At the same time, the need to develop a moral philosophy consistent with the Reformed creed became the centre of the debate between Revius and Heidanus, a Reformed theologian who saw in Cartesianism a philosophy more consistent with Calvinism than Scholasticism. Accordingly, he was eager to support the appointment in Leiden of Arnold Geulincx, who was developing a philosophical ethics independent of revealed theology but consistent with the Reformed creed. For this purpose, besides the relation of body, soul and world, Geulincx considered those relations of man, world, and God from which moral duties follow. Accordingly, he provided his ethics with a foundation in rational theology. In turn, this foundation entails a reflection on the type of knowledge that constitutes physics and determines its very method. Given the inscrutability of God’s reasons in creating the world, Geulincx could claim that physics has to proceed by hypotheses based on experience rather than by a deduction of natural laws from metaphysical principles. In this way, the epistemic consequences of his foundational theory refuelled a reflection on the method of natural philosophy itself, making his foundation a sample of the transformation of Cartesian foundationalism – dominated by Descartes’s metaphysical physics – into a reflection on physics itself. In other words, Geulincx provided, together with De Raey, a de-metaphysicisation of physics. (shrink)

The most prevalent modes of philosophy, educational theory, and philosophy of education currently extant in the United States represent a pronounced departure from the fundamental patterns of the Greek-Jewish- Christian tradition. Among the noteworthy characteristics of the more popular trends is a tendency toward the denial of, or an indifference regarding, the existence of a Transcendent Being. This feature alone has effected a radical departure from the scholarly traditions which are characterized by investigations into the relationships between theology and philosophy. (...) This factor, in turn, bears potentially strong influence upon the theory and practice of education. Partially in order to promote the revivification of a heritage not unrelated to that of many early American intellectual leaders, the main purpose of this paper is to exemplify the structure and an aspect of the substance of a theology-philosophy of Catholic education in accord with a selected passage from A New Catechism: Catholic Faith for Adults. The theological-philosophical dimension of this structure is represented by a developmental process entailing three stages of progression: from human love through an awareness of the “God of the philosophers” to belief in Christ. It is shown how theological and philosophical elements of this process bear upon the importance of early childhood religious education as well as of Catholic education somewhat more broadly conceived. It is noted that, although the theological-philosophical foundations allow for numerous options in education, there are bounds within which the direction of this education must be retained. The current importance of this kind of investigation lies in 1) the fundamentally empiricist approaches in philosophy of education so prominent today, 2) the inability of empiricist philosophies to confront prescriptive values in an authentically rational fashion, and 3) the necessity of a theological-philosophical approach for the Christian who wishes to think rationally about prescriptive values, and to formulate the kinds of educational plans which will prove to be effective in promoting authentic human happiness. Brief references to the practical efficacy of theoretical conceptions, and to teacher education, conclude the paper. (shrink)

1848 is a watershed in Dutch political and intellectual history. In the wake of liberalism positivism and empiricism dominated Dutch philosophy. In this paper it is argued that Spinoza’s philosophy played an important part in developing a liberal Weltanschauung. Dutch Spinozism started with the theological dissertation of Johannes van Vloten, who from the 1860s onwards became the great pamphleteer of Spinozism. However due to his break with Christianity he remained an exception in Dutch intellectual life. The (...) Utrecht professor of philosophy Cornelis Willem Opzoomer and his friend the classical scholar D. Burger jr., for example, propagated a liberal Christianity purged from its mythical elements. Adopting Schleiermacher’s example Opzoomer developed a morality inspired by Ethics V. In 1850 he turned to J. S. Mill and A. Comte. From that year onwards he justified the methodological unity of the natural and ‘moral’ sciences in Spinoza’s doctrine of the passions. According to Burger the Ethics contains an obsolete metaphysics, but due to its morality consistent with science the book deserves a large 19th-century readership. In 1858 he translated Spinoza’s main work into Dutch. (shrink)

A handful of well-known arguments (the 'diachronic Dutch book arguments') rely upon theorems establishing that, in certain circumstances, you are immune from sure monetary loss (you are not 'diachronically Dutch bookable') if and only if you adopt the strategy of conditionalizing (or Jeffrey conditionalizing) on whatever evidence you happen to receive. These theorems require non-trivial assumptions about which evidence you might acquire---in the case of conditionalization, the assumption is that, if you might learn that e, then it is (...) not the case that you might learn something else that is consistent with e. These assumptions may not be relaxed. When they are, not only will non-(Jeffrey) conditionalizers be immune from diachronic Dutch bookability, but (Jeffrey) conditionalizers will themselves be diachronically Dutch bookable. I argue: 1) that there are epistemic situations in which these assumptions are violated; 2) that this reveals a conflict between the premise that susceptibility to sure monetary loss is irrational, on the one hand, and the view that rational belief revision is a function of your prior beliefs and the acquired evidence alone, on the other; and 3) that this inconsistency demonstrates that diachronic Dutch book arguments for (Jeffrey) conditionalization are invalid.

This book attempts to provide a general interpretation of the history of philosophy in the seventeenth-century Dutch Republic.

From 1980 until 1985, the Dutch Faculties of Philosophy went through a period of transition. First, in 1982 the national government introduced a new system of financing research at the universities. This was essentially based on the natural sciences and did not match philosophers' work organization. In 1983 a drastic reduction in the budget for philosophy was proposed within the framework of a policy of introducing savings by distributing tasks among the universities. Recently, a visiting committee reported on the (...) weak and strong areas of Dutch philosophy and proposed a policy to strengthen Dutch philosophy. This study explores the effects of the institutional reorganizations on the study of philosophy at the faculties, using scientometric methods. In addition to presenting empirical results, some methodological questions concerning the application of scientometric methods to a field of the humanities will be discussed. The number of publications went up as funding was cut back and different subfields made different kinds of changes in orientation. The results show the relevance of publication-based data in research evaluation. (shrink)

Trude Dijkstra discusses how Chinese religion and philosophy were represented in printed works produced in the Dutch Republic between 1595 and 1700. By focusing on books, newspapers, learned journals, and pamphlets, this study sheds new light on the cultural encounter between China and western Europe in the early modern period. Form, content, and material-technical aspects of different media in Dutch and French are analysed, providing new insights into the ways in which readers could take note of Chinese religion (...) and philosophy. This study thereby demonstrates that there was no singular image of Chinese religion and philosophy, but rather a varied array of notions on the subject. (shrink)

In This Paper I Aim to Place Spinoza’s famous injunction in the Tractatus Theologico-Politicus, to separate philosophy from theology, in its historical context. I contend that in order to properly understand Spinoza’s views concerning the relationship between philosophy and theology, we must view his work in the context of philosophical discussions taking place during his time and in his country of residence, the Dutch Republic. Of particular relevance is a meta-philosophical thesis advocated by a certain group of Cartesian philosophers (...) and theologians. Their thesis was developed in response to attacks on Cartesianism from more conservative authors, who saw it as a source of impiety. It stated that Cartesian .. (shrink)

The most immediately appealing model for formal constraints on degrees of belief is provided by probability theory, which tells us, for instance, that the probability of P can never be greater than that of (P v Q). But while this model has much intuitive appeal, many have been concerned to provide arguments showing that ideally rational degrees of belief would conform to the calculus of probabilities. The arguments most frequently used to make this claim plausible are the so-called "Dutch (...) Book" arguments. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Dutch Cartesianism and the Birth of Philosophy of Science by Andrea StrazzoniAaron SpinkAndrea Strazzoni. Dutch Cartesianism and the Birth of Philosophy of Science. Berlin: Walter de Gruyter, 2019. Pp. ix + 245. Hardback, $124.99.Andrea Strazzoni's Dutch Cartesianism and the Birth of Philosophy of Science is a clear step forward in our understanding of the rise and fall of Cartesianism. The work, limited to the (...) class='Hi'>Dutch context with one notable German excursion, covers roughly one hundred years starting from the 1630s. While the time frame is rather large in scope, the majority of the work is narrower in focus, with a heavy emphasis on the academic circles in mid-to-late seventeenth-century Leiden and Utrecht. It is thus a welcome addition to the growing body of literature dealing with the unique political, religious, and academic contexts in which Dutch Cartesians found themselves. While much of the book deals with the philosophy of Descartes and then Newton, Strazzoni is not concerned with giving any novel interpretations of either figure; instead, he sheds a great deal of light on a cast of characters who are only now coming to be appreciated for their contributions and influence on philosophical movements of the seventeenth and early eighteenth centuries. The book has two main explicit goals. First, Strazzoni wants to show why foundationalism came to play such a prominent role in Dutch Cartesian circles and what foundationalism's effects were. Second, through this examination, Strazzoni hopes to show that the multiplication of worldviews [End Page 154] shaped a new function for metaphysics and logic as tools for examining principles, which in turn determined a change in the function of philosophy itself that eventually gave birth to a kind of philosophy of science familiar to us today.Strazzoni divides this project into eight chapters, with a focus on six figures: Henricus Regius, Johannes Clauberg, Johannes de Raey, Arnold Geulincx, Burchard de Volder, and Willem Jacob's Gravesande. In addition to a brief overview of the goals and structure of the work, the first chapter includes a survey of how methodologies have changed in the history of philosophy and the history of the philosophy of science, which will be helpful background for those less familiar with the fields.The following two chapters deal with the crises that emerged in Utrecht and Leiden over the spread of Cartesian philosophy. In chapter 2, building on Theo Verbeek's work, Regius takes center stage. While some context of the Utrecht crisis is given, Strazzoni spends much of the chapter detailing how Regius's medical background led to a more empirical approach and lack of metaphysical foundation. While Regius's own controversial positions embroiled both himself and Descartes in the Utrecht Crisis, ripple effects spread to Leiden, resulting in prohibitions against discussions of Cartesian philosophy. In the third chapter, Strazzoni highlights a group of anti-Cartesians, with Jacob Revius as the primary antagonist, and the responses from De Raey and Clauberg. Clauberg, the subject of Strazzoni's only sustained discussion of Cartesianism from Germany, coordinated with de Raey on both a positive campaign of promotion and strategizing responses to the anti-Cartesian front. Outside of discussing Clauberg's explicit role in Leiden, Strazzoni studies his logic and Ontosophia, neatly explaining his shift to more metaphysical foundations.Chapters 4, 5, and 6 continue exploring the various approaches and roles for foundational philosophy in more detail, delving into how these controversies motivated renewed analysis of core Cartesian principles with integration into an academic curriculum in mind. Apart from de Raey's efforts to show that Cartesianism was aligned with Aristotelianism, Strazzoni claims a period of Cartesian physics without an explicit preoccupation with metaphysical questions, especially in light of the restrictions imposed by the curators of Leiden's university. However, as Spinoza and Hobbes came to prominence, multiplying the number of philosophical worldviews, foundational arguments were needed to combat them. Strazzoni highlights how varied these responses could be, as Geulincx's own take on foundations leaned heavily toward ethics rather than epistemology, metaphysics, or logic. However, the discussion of Geulincx is much broader, also including illuminating expositions of Geulincx's theology, epistemology, and metaphysics.Chapter 5 expounds further... (shrink)

There is a general sense that the philosophy of Descartes was a dominant force in early modern thought. Since the work in the nineteenth century of French historians of Cartesian philosophy, however, there has been no fully contextualized comparative examination of the various receptions of Descartes in different portions of early modern Europe. This study addresses the need for a more current understanding of these receptions by considering the different constructions of Descartes's thought that emerged in the Calvinist United Provinces (...) and Catholic France, the two main centers for early modern Cartesianism, during the period dating from the last decades of his life to the century or so following his death in 1650. It turns out that we must speak not of a single early modern Cartesianism rigidly defined in terms of Descartes's own authorial intentions, but rather of a loose collection of early modern Cartesianisms that involve a range of different positions on various sets of issues. Though more or less rooted in Descartes's somewhat open-ended views, these Cartesianisms evolved in different ways over time in response to different intellectual and social pressures. Chapters of this study are devoted to: the early modern Catholic and Calvinist condemnations of Descartes and the incompatible Cartesian responses to these; conflicting attitudes among early modern Cartesians toward ancient thought and modernity; competing early modern attempts to combine Descartes's views with those of Augustine; the different occasionalist accounts of causation within early modern Cartesianism; and the impact of various forms of early modern Cartesianism on both Dutch medicine and French physics.

Dutch Book Arguments (DBAs) have been invoked to support various requirements of rationality. Some are plausible: probabilism and conditionalization. Others are less so: credal transparency and reflection. Anna Mahtani has argued for a new understanding of DBAs which, she claims, allow us to keep the DBAs for probabilism (and perhaps conditionalization) and reject the DBAs for credal transparency and reflection. I argue that Mahtani’s new account fails as (a) it does not support highly plausible requirements of rational coherence and (...) (b) it does not, even setting aside the first objection, succeed in undermining the DBAs for credal transparency or reflection. (shrink)

Two criticisms of Dutch strategy arguments are discussed: One says that the arguments fail because agents who know the arguments can use that knowledge to avoid Dutch strategy vulnerability, even though they violate the norm in question. The second consists of cases alleged to be counterexamples to the norms that Dutch strategy arguments defend. The principle of Reflection and its Dutch strategy argument are discussed, but most attention is given to the rule of Conditionalization and to (...) Jeffrey's rule for fallible learning. I argue that the first criticism should be rejected, and that the second presents no counterexamples to the rationality of commitment to the rules. (shrink)

We investigate how Dutch Book considerations can be conducted in the context of two classes of nonclassical probability spaces used in philosophy of physics. In particular we show that a recent proposal by B. Feintzeig to find so called “generalized probability spaces” which would not be susceptible to a Dutch Book and would not possess a classical extension is doomed to fail. Noting that the particular notion of a nonclassical probability space used by Feintzeig is not the most (...) common employed in philosophy of physics, and that his usage of the “classical” Dutch Book concept is not appropriate in “nonclassical” contexts, we then argue that if we switch to the more frequently used formalism and use the correct notion of a Dutch Book, then all probability spaces are not susceptible to a Dutch Book. We also settle a hypothesis regarding the existence of classical extensions of a class of generalized probability spaces. (shrink)

Recently a number of authors have tried to avoid the failures of traditional Dutch book arguments by separating them from pragmatic concerns of avoiding a sure loss. In this paper I examine defenses of this kind by Howson and Urbach, Hellman, and Christensen. I construct rigorous explications of their arguments and show that they are not cogent. I advocate abandoning Dutch book arguments in favor of a representation theorem.

Food consumption has been identified as a realm of key importance for progressing the world towards more sustainable consumption overall. Consumers have the option to choose organic food as a visible product of more ecologically integrated farming methods and, in general, more carefully produced food. This study aims to investigate the choice for organic from a cultural–historical perspective and aims to reveal the food philosophy of current organic consumers in The Netherlands. A concise history of the organic food movement is (...) provided going back to the German Lebensreform and the American Natural Foods Movement. We discuss themes such as the wish to return to a more natural lifestyle, distancing from materialistic lifestyles, and reverting to a more meaningful moral life. Based on a number of in-depth interviews, the study illustrates that these themes are still of influence among current organic consumers who additionally raised the importance of connectedness to nature, awareness, and purity. We argue that their values are shared by a much larger part of Dutch society than those currently shopping for organic food. Strengthening these cultural values in the context of more sustainable food choices may help to expand the amount of organic consumers and hereby aid a transition towards more sustainable consumption.

Dutch Book arguments have been presented for static belief systems and for belief change by conditionalization. An argument is given here that a rule for belief change which under certain conditions violates probability kinematics will leave the agent open to a Dutch Book.

The ‘model approach’ facilitates a quantitative-oriented study of conceptual changes in large corpora. This paper implements the ‘model approach’ to investigate the erosion of the traditional art-nature distinction in early modern natural philosophy. I argue that a condition for this transformation has to be located in the late scholastic conception of final causation. I design a conceptual model to capture the art-nature distinction and formulate a working hypothesis about its early modern fate. I test my hypothesis on a selected corpus (...) of 25 works published in the Dutch academic milieu between 1607 and 1748. I analyse the corpus through a procedure based on concordancing of keywords associated with the model. I argue that the results obtained constitute a successful pilot study for the implementation of the model approach on larger scale research. (shrink)

In this paper, I present an argument for a rational norm involving a kind of credal attitude called a quantificational credence – the kind of attitude we can report by saying that Lucy thinks that each record in Schroeder’s collection is 5% likely to be scratched. I prove a result called a Dutch Book Theorem, which constitutes conditional support for the norm. Though Dutch Book Theorems exist for norms on ordinary and conditional credences, there is controversy about the (...) epistemic significance of these results. So, my conclusion is that if Dutch Book Theorems do, in general, support norms on credal states, then we have support for the suggested norm on quantificational credences. Providing conditional support for this norm gives us a fuller picture of the normative landscape of credal states. (shrink)

Review of Alexander X. Douglas, Spinoza and Dutch Cartesianism: Philosophy and Theology.

While strolling the streets of Amsterdam, Sidney Smith, the renowned editor of the Edinburgh Review, called the attention of his companion to two Dutch housewives who were leaning out of their windows and arguing with one another across the narrow alley that separated their houses. Smith remarked to his companion that the two women would never agree. His friend thought the seasoned editor had in mind the stubborn Dutch character. No, said Smith. Rather it was because they were (...) arguing from different premises. In recent articles, Stephen Ball (1988) and Bart Voorzanger (1987) have objected strongly to my defense of evolutionary ethics. In their reconstruction of my arguments, however, they have assigned to me premises different from those upon which my original defense stood. Their objections may demolish the arguments they have reconstructed, but fortunately my theory does not reside thereon. They have made Dutch objections. (shrink)

I consider Dutch Book arguments for three principles of classical Bayesianism: (i) agents' belief-probabilities are consistent only if they obey the probability axioms. (ii) beliefs are updated by Bayesian conditionalisation. (iii) that the so-called Principal Principle connects statistical and belief probabilities. I argue that while there is a sound Dutch Book argument for (i), the standard ones for (ii) based on the Lewis-Teller strategy are unsound, for reasons pointed out by Christensen. I consider a type of Dutch (...) Book argument for (iii), where the statistical probability is a von Mises one. (shrink)

This article describes and analyses the development of modern irrigation in Java within the context of the establishment and transformation of the colonial state in the Dutch East Indies / Indonesia. In order to make this relationship comprehensible the concept “large technical system” has been adopted. The colonial socio-technical irrigation system was built between 1830 and 1942. Engineers, civil servants and agricultural experts were the main system builders and they formed specific coalitions practising specific irrigation approaches. After Indonesia gained (...) its independence, the colonial irrigation system remained in existence and, consequently, irrigation engineering remained top-down, large-scale and focused on agricultural-technical management.

The recent Dutch homo-emancipation policy has identified religious communities, particularly within migrant populations, as a core target group in which to make homosexuality more ‘speakable’. In this article we examine the paradoxical silencing tendencies of this ‘speaking out’ policy on queer Muslim organisations in the Netherlands. We undertake this analysis as the Dutch government is perhaps unique in developing an explicit ‘homo-emancipation’ policy and is often looked to as the model for sexuality politics and legal redress in relation (...) to inequalities on the basis of sexual orientation. We highlight how the ‘speakability’ imperative in the Dutch homo-emancipation policy reproduces a paradigmatic, ‘homonormative’ model of an ‘out’ and ‘visible’ queer sexuality that has also come to be embedded in an anti-immigrant and specifically anti-Muslim discourse in the Netherlands. Drawing on the concept of habitus, particularly in the work of Gloria Wekker, we suggest that rather than relying on a ‘speakability’ policy model, queer Muslim sexualities need to be understood in a more nuanced and intersecting way that attends to their lived realities.

“Dutch Book” arguments and references to gambling theorems are typical in the debate between Bayesians and scientists committed to “classical” statistical methods. These arguments have rarely convinced non-Bayesian scientists to abandon certain conventional practices, partially because many scientists feel that gambling theorems have little relevance to their research activities. In other words, scientists “don’t bet.” This article examines one attempt, by Schervish, Seidenfeld, and Kadane, to progress beyond such apparent stalemates by connecting “Dutch Book”–type mathematical results with principles (...) actually endorsed by practicing experimentalists.
