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)

Bacon’s philosophy had a wide dissemination in Dutch Seventeenth Century context. This can be explained by the coeval diffusion of Cartesianism. Bacon’s project of a reformation of science was deemed by Heereboord and De Raey as the manifesto of a new philosophy. Along with Geulincx, moreover, De Raey borrowed Bacon’s arguments on the causes of error and on the replacement of Aristotelian natural history, aimed at integrating Descartes’s physics. Also in logic Bacon’s influence was noticeable, as the (...) development of a new Organon had its accomplishment in the Cartesian logic of Clauberg and of De Raey himself. In theology, Heidanus relied on Bacon in order to confute Socinianism. The fortune of Dutch Baconianism had its end with the rise of Newtonianism: as a quantitative, experimental philosophy arose, Bacon’s works were no more regarded as a valuable source of arguments.

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.

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)

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)

In this brief text, I will sketch developments in the philosophy of technology in the Netherlands and in Europe since Paul Durbin published his extensive study on the state of the field in 2006.

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.

“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.

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)

Herman Philipse considers “religious beliefs, faith and religion [to be] incompatible with science or reason”; he defines religion scientifically and specifically rejects religious doctrine. He describes reason “… as the whole of methods of empirical scientific research and critical discursive thinking as they have evolved in the scientific tradition and will continue to develop in the future” and he defines “… the phenomenon of conscience as a mental organ that can be scientifically explained and that makes the religious explanation superfluous (...) …”. Herman Philipse classifies science as the highest in rank, discards religion and sees philosophy, a rational view of the world, as based solely on the sciences. For his subject, Hans Achterhuis “… primarily cites biologists, ethologists and evolutionary psychologists with a philosophical interest” because “they presently have more to offer [him] than do his immediate colleagues”. Furthermore, “… it will be clear that ethologists and sociobiologists are of the opinion that the violent behaviour of human beings must be understood in part from the point of view of the evolutionary history of the sort ….. most philosophers and anthropologists are not aware of this. Their considerations suggest that violence only entered our world together with humankind”. Achterhuis’s choice is a “historic concept of violence”. (shrink)

Why is it good to be less, rather than more incoherent? Julia Staffel, in her excellent book “Unsettled Thoughts,” answers this question by showing that if your credences are incoherent, then there is some way of nudging them toward coherence that is guaranteed to make them more accurate and reduce the extent to which they are Dutch-bookable. This seems to show that such a nudge toward coherence makes them better fit to play their key epistemic and practical roles: representing (...) the world and guiding action. In this paper, I argue that Staffel’s strategy needs a small tweak. While she identifies appropriate measures of epistemic value, she does not identify appropriate measures of practical value. Staffel measures practical value using Dutchbookability scores. But credences have practical value in virtue of recommending actions that produce as much utility as possible. And while susceptibility to a Dutch book is a surefire sign that one’s credences are needlessly bad at this task, one’s degree of Dutch-bookability is not itself a good measure of how well they recommend practically valuable actions. Strictly proper scoring rules, I argue, are the right tools for measuring both epistemic and practical value. I show that we can rerun Staffel’s strategy swapping in strictly proper scoring rules for Dutch-bookability measures. So long as one’s epistemic scoring rule and practical scoring rule are “sufficiently similar,” there is some way of nudging incoherent credences toward coherence that is guaranteed to yield more of both types of value.

This paper discusses the connection between epistemic virtues and chemistry in the eighteenth century Dutch Republic. It does so in two ways. First, it presents the virtue epistemology of three Dutch university professors and natural philosophers: Herman Boerhaave, Petrus van Musschenbroek, and Johannes David Hahn. It shows how their criticism of a priori philosophy and their defence of experimental natural philosophy is connected to a specific virtue epistemology. Four epistemic virtues are central for these authors: intellectual (...) patience, diligence and humility, and impartiality. This virtue epistemology informs their presentation of chemistry as an exemplary discipline. The practice of chemistry instils these key epistemic virtues in its practitioners. Second, the article shows how these epistemic virtues also play a role in later debates regarding the reception of Lavoisier’s work in the Dutch Republic. This article hopes to provide an example of what Ian Kidd has called a ‘deep conception of epistemic vice [and virtue]’. It also argues for the fruitfulness of applying a virtue epistemic framework to the study of the Chemical Revolution. (shrink)

Hegel was ambivalent about Dutch genre painting’s uncanny ability to find beauty in daily life. The philosopher regarded the Dutch painterly aesthetic as Romanticism avant la lettre, and classifies it as such in his Lectures on Aesthetics, under the section entitled “Die romantischen Künste [The Romantic arts].”1 Dutch art, in Hegel’s reading, is marred by many shortcomings. The most prominent among these are the “subjective stubbornness [subjective Beschlossenheit]” that prevents this art from attaining to the “free and (...) ideal forms of expression” that marked the productions of Italian artists such as Raphael. In contradistinction to their Italian counterparts, Dutch artists in Hegel’s view are apt to. (shrink)

In this paper, we ask: how should an agent who has incoherent credences update when they learn new evidence? The standard Bayesian answer for coherent agents is that they should conditionalize; however, this updating rule is not defined for incoherent starting credences. We show how one of the main arguments for conditionalization, the Dutch strategy argument, can be extended to devise a target property for updating plans that can apply to them regardless of whether the agent starts out with (...) coherent or incoherent credences. The main idea behind this extension is that the agent should avoid updating plans that increase the possible sure loss from Dutch strategies. This happens to be equivalent to avoiding updating plans that increase incoherence according to a distance-based incoherence measure. (shrink)

In Genesis we are told that God gathered the waters into one place, in order to let the dry land appear, which He called earth, while the waters were called seas. In the Netherlands, this process took more than a single day, and it was the work of man. Gradually, a cultivated landscape emerged out of diffuse nature. In the course of centuries, the Dutch determined the conditions that allowed different aspects of nature to present themselves. This process is (...) described as a moral geography in the sense that different types of landscape are read as a manifestations of different moral attitudes towards nature, whereas concrete landscape interventions are interpreted as instances of moral criticism directed towards the activities and values of previous generations. At present, this process is being reversed, as diffuse, wetland nature is experiencing a come-back. (shrink)

An objection to shifty epistemologies such as subject-sensitive invariantism is that it predicts that agents are susceptible to guaranteed losses. Bob Beddor (Analysis, 81, 193–198, 2021) argues that these guaranteed losses are not a symptom of irrationality, on the grounds that forgetful agents are susceptible to guaranteed losses without being irrational. I agree that forgetful agents are susceptible to guaranteed losses without being irrational– but when we investigate why, the analogy with shifty epistemology breaks down. I argue that agents with (...) shifty epistemologies are susceptible to guaranteed losses in a way which is a symptom of irrationality. Along the way I make a suggestion about what it takes for an agent to be coherent over time. I close by offering a taxonomy of shifty epistemologies. (shrink)

This article offers an account of the philosophy of language expounded in the Cogitata de interpretatione (1692) of the Dutch philosopher Johannes De Raey (1620-1702). In this work, De Raey provided a theory of the formation and meaning language based on the metaphysics of René Descartes. De Raey distinguished between words signifying passions and sensations, ideas of the intellect, or external things. The aim of this article is to shift away the discussion of De Raey’s critique on the (...) application of the language of practical matters by Lodewijk Meijer and Spinoza, and to redirect modern interpretations to the originality of De Raey’s own reflections on the uses of language. In his linguistic thought, De Raey criticized philosophers such as Hobbes, who supposedly deprived Aristotelian terminology of any reference and meaningful use. The analysis of De Raey testifies to the emergence of the philosophy of language out of the double traditions of logic and metaphysics. It is to be interpreted as an effect of the emergence of an alternative worldview to Aristotelianism. This called for an update of the semantic catalogue of philosophy and practical disciplines.

The articles in the special issue "Experience in natural philosophy and medicine" discuss the roles and notions of experience in the works of a range of early modern authors, including Galileo Galilei, Francis Bacon, the Dutch atomist David Gorlaeus, William Harvey, and Christian Wolff.

They shed light on (...) the longstanding influence of traditional views and the emergence of early modern experimental philosophy. This introduction highlights the benefits of considering medicine in connection with natural philosophy when studying early modern views on experience and summarizes the articles. (shrink)

The term ‘heat’ originates from the Old English word hǣtu, a word of Germanic origin; related to the Dutch ‘hitte’ and German ‘Hitze’. Today, we distinguish three different meanings of the word ‘heat’. First, ‘heat’ is understood in colloquial English as ‘hotness’. There are, in addition, two scientific meanings of ‘heat’. ‘Heat’ can have the meaning of the portion of energy that changes with a change of temperature. And finally, ‘heat’ can have the meaning of the transfer of thermal (...) energy from a hotter to a colder system or body. By contrast, for the Ancients and Scholastics, ‘heat’ was a manifest, real quality of bodies and there was an ontological distinction between biological or innate heat (which was regarded as an innate principle of life for warm-blooded animals) and the physical manifest heat of external objects, which is potentially harmful. During the late Renaissance period, however, both views changed fundamentally and evolved - via the application of physical and mechanical analogies - into the foundations for today’s unified mechanistic theory of heat.

This article examines the seventeenth-century debate between the Dutch philosopher Benedict de Spinoza and the British scientist Robert Boyle, with a view to explicating what the twentieth-century French philosopher Gilles Deleuze considers to be the difference between science and philosophy. The two main themes that are usually drawn from the correspondence of Boyle and Spinoza, and used to polarize the exchange, are the different views on scientific methodology and on the nature of matter that are attributed to each (...) correspondent. Commentators have tended to focus on one or the other of these themes in order to champion either Boyle or Spinoza in their assessment of the exchange. This paper draws upon the resources made available by Gilles Deleuze and Felix Guattari in their major work What is Philosophy?, in order to offer a more balanced account of the exchange, which in its turn contributes to our understanding of Deleuze and Guattari’s conception of the difference between science and philosophy.

The present study defines the function of the foundation of science in early modern Dutch philosophy, from the first introduction of Cartesian philosophy in Utrecht University by Henricus Regius to the acceptance of Newtonian physics by Willem Jacob ‘s Gravesande. My main claim is that a foundation of science was required because the conceptual premises of new ways in thinking had to be justified not only as alternatives to the established philosophical paradigms or as an answer to (...) the “sceptical crisis” signalled by Richard Popkin, but also in order to be introduced in the academia. This being my general thesis, different kinds of foundation of scientific knowledge are analysed in the light of the specific problems philosophers had to face. To this end, foundational theories are analysed in the light of 1) the overall aim of their philosophy, 2) the relations of disciplines they thought out, 3) what they regarded as scientific knowledge. Through this analysis, I assess that the foundation of science was carried out by metaphysical, logical and theological arguments, which fitted the needs of answering the didactical and introductory requirements of new paradigms, assessed the reliability of new methodology in leading us to grasp the truth, and provided philosophy with its conceptual apparatus. Finally, I demonstrate that a philosophy of science as a reflection on the principles, methods, concepts and application of modern science emerged in the Dutch Republic. (shrink)

En filosofía es importante conocer las influencias entre los filósofos porque de ello depende tener un conocimiento más completo y preciso de sus propuestas. Ejemplo de esto son las investigaciones sobre los orígenes estoicos de la filosofía spinoziana, que se han incrementado notablemente en las últimas décadas, pero aún hace falta indagar con mayor detalle, autor por autor e idea por idea, qué tipo de estoicismo y qué parte del mismo influyó en el pensador neerlandés.

The aim of this article is to unveil the ways of teaching new philosophical paradigms in Dutch Universities between Seventeenth and Eighteenth Century, by means of an analysis of the uses of illustrations in Cartesian and Newtonian natural-philosophical textbooks. This analysis allows to understand the overall functions of philosophical textbooks, where illustrations act as conceptual means, filling the gap between the premise of a theory and its actual contents; didactic means, aiming to help the reader in understanding scientific models (...) fully explained in texts; promoting or propagandistic instruments, useful to present theories in a fascinating way. Eventually, I argue for a positive correlation of the use of illustrations and the introduction of new philosophies, and for the existence of non-philosophical reasons for such use: as to the propagandistic function of illustrations intended as decorative means.

LLMs have dramatically improved in capabilities in recent years. This raises the question of whether LLMs could become genuine agents with beliefs and desires. This paper demonstrates an in principle limit to LLM agency, based on their architecture. LLMs are next word predictors: given a string of text, they calculate the probability that various words can come next. LLMs produce outputs that reflect these probabilities. I show that next word predictors are exploitable. If LLMs are prompted to make probabilistic predictions (...) about the world, these predictions are guaranteed to be incoherent, and so Dutch bookable. If LLMs are prompted to make choices over actions, their preferences are guaranteed to be intransitive, and so money pumpable. In short, the problem is that selecting an action based on its potential value is structurally different then selecting the description of an action that is most likely given a prompt: probability cannot be forced into the shape of expected value. The in principle exploitability of LLMs raises doubts about how agential they can become. This exploitability also offers an opportunity for humanity to safely control such AI systems. (shrink)

The philosophy of Francis Bacon was interpreted in various ways in the seventeenth century. In England, his utopian project and natural history became the basis for the projects of religious pacification, pedagogical reformation, and scientific cooperation of Hartlib, Comenius and Charleton. In the hands of Evelyn, Wilkins, and Wren, moreover, Bacon’s ideal of cooperative science engendered the birth of the Royal Society, and his natural history guided the experimental activities of Boyle and Hooke. In France and the Netherlands, attention (...) was paid to Bacon’s natural history especially within the circle of friends of Descartes. In the second half of the seventeenth century, though Bacon’s historical approach was gradually supplanted by mechanical-mathematical science in Europe, Baconianism still served as a source of arguments in the Dutch Cartesian context, as to his theory of error and as a source of criticisms to Aristotelianism.

De Finetti would claim that we can make sense of a draw in which each positive integer has equal probability of winning. This requires a uniform probability distribution over the natural numbers, violating countable additivity. Countable additivity thus appears not to be a fundamental constraint on subjective probability. It does, however, seem mandated by Dutch Book arguments similar to those that support the other axioms of the probability calculus as compulsory for subjective interpretations. These two lines of reasoning can (...) be reconciled through a slight generalization of the Dutch Book framework. Countable additivity may indeed be abandoned for de Finetti's lottery, but this poses no serious threat to its adoption in most applications of subjective probability.

The search for an agreement between Aristotle’s and Descartes’ philosophy was aimed at making Cartesian physics acceptable in the Dutch universities by showing its consistency with Aristotelian thought. Their agreement is defended by Johannes De Raey in the Clavis philosophiae naturalis (1654), where he interprets the Corpus Aristotelicum from a Cartesian standpoint. Those Aristotelian positions which are inconsistent with Descartes’ are treated as erroneous. The Scholastic positions, moreover, are considered as distant from the true Aristotelian philosophy rediscovered (...) by Descartes. (shrink)

In 1675, Burchard de Volder became the first university physics professor to introduce the demonstration of experiments into his lectures and to create a special university classroom, The Leiden Physics Theatre, for this specific purpose. This is surprising for two reasons: first, early pre-Newtonian experiment is commonly associated with Italy and England, and second, de Volder is committed to Cartesian philosophy, including the view that knowledge gathered through the senses is subject to doubt, while that deducted from first principles (...) is certain. On the surface, it is curious that such a man would bring experiments to university physics. After all, in demonstrating experiments to his students, he was teaching them through their senses, not reason. However, if we consider the institutional context of de Volder’s teaching, we come to see de Volder’s Cartesian experimentalism as representative of a certain form of pre-Newtonian Dutch Cartesian science, as well as part of a larger tradition of teaching through observation at the University of Leiden. Considering de Volder’s institutional context will help us see that de Volder’s experimentalism was not in spite of his Cartesianism, but motivated by it. This paper will describe de Volder’s physics curriculum, the Theatre in which it was taught and how his work predates similar efforts in other European Universities. The second part will consider three aspects of the culture at the University of Leiden: a tradition of teaching through observation, a particular reception of Cartesianism, and an eclectic approach to the New Philosophy. The concluding portion shows how de Volder would have understood his enterprise in Cartesian terms. (shrink)

Abstract: This article explores the medical theories of the Dutch philosopher and physician Henricus Regius (1598-1679), who sought to provide clearer notions of medicine than the traditional theories of Jean Fernel, Daniel Sennert and Vopiscus Plempius. To achieve this, Regius overtly built upon the natural philosophy of René Descartes, in particular his theories of mechanical physiology and the corpuscular nature of matter. First, I show that Regius envisaged a novel partitioning of medicine, intended to make it independent in (...) exposition but conceptually grounded in natural philosophy. This served his overall purpose of making medicine a ‘clearer’ discipline. To this end Regius detaches the general notion of physiology as the study of the human body (which pertains to natural philosophy) from a medical physiology that concerns only health. Secondly, I show that Regius’s notions of health, disease, temperament and medicaments were the product of a Cartesian interpretation of traditional concepts, which was influenced by Santorio Santorio’s project of practicing medicine without occult elements. As a consequence, Regius’s classification of these notions is largely traditional. In conclusion, I show that Regius’s method of investigation in the area of natural philosophy consisted of a problem-solving procedure based on sensorial ideas. This approach can be traced back to Descartes, but was grounded on a purely empirical theory of knowledge, by which he rejected Descartes’s metaphysics. Regius’s order of exposition in natural philosophy and medicine, on the other hand, proceeds by definitions and divisions, and omits proofs. The reasons why Regius adopted this order were: 1) his rejection of Descartes’s metaphysical interpreta-tion of physics, and 2) his wish to emphasize the conceptual clarity and continuity of natural philosophy and medicine.

In this paper we explore the absentminded driver problem using two different scenarios. In the first scenario we assume that the driver is capable of reasoning about his degree of absentmindedness before he hits the highway. This leads to a Savage-style model where the states are mutually exclusive and the act-state independence is in place. In the second we employ centred possibilities, by modelling the states (i.e. the events about which the driver is uncertain) as the possible final destinations indexed (...) by a time period. The optimal probability we find for continuing at an exit is different from almost all papers in the literature. In this scenario, act-state independence is still violated, but states are mutually exclusive and the driver arrives at his optimal choice probability via Bayesian updating. We show that our solution is the only one guaranteeing immunity from sure loss via a Dutch strategy, and that – despite initial appearances – it is time consistent. This raises important implications for the rationality of commitment in such scenarios. (shrink)

This article analyses in detail Wittgenstein’s ‘Cambridge period’ from his return to Cambridge in 1929 until his decease in 1951. Within the ‘Cambridge period’, scholars usually distinguish the ‘middle’ (1929–1936) and the ‘late’ (1936–1951) periods. The trigger point of Wittgenstein’s return to Cambridge and philosophy was his visit to Brouwer’s lecture on ‘Mathematics, Science, and Language’ in Vienna in March 1928. Dutch mathematician Brouwer influenced not only Wittgenstein’s ability to do philosophy again but also the development of (...) some of his ideas. Namely, for Brouwer, language was a natural development of the social history of human beings. With the help of his friends, F. P. Ramsey, J. M. Keynes, G. E. Moore, and B. Russell, in 1929 Wittgenstein returned to Cambridge. The author argues that this was the crucial turning point in his philosophy that led to the revision of some of his ideas. Wittgenstein returned from self-isolation in remote villages of Lower Austria to the intellectual academic environment, where he could discuss his ideas with intellectual interlocutors and receive their valuable remarks and comments. This article is organised in chronological order: it describes the very ‘early’ middle period of 1929–1935 involving the development of Wittgenstein’s ‘phenomenology’ and the origin of the ‘language-games’ concept in the Blue and Brown Books; 1935–1936 period of ‘romantic’ enthusiasm for Soviet Russia and a trip there; Wittgenstein’s life and work during the WWII-time; resign from teaching in Cambridge in 1947 to finally finish his Philosophical Investigations. The author suggests that the ‘romantic areal’ about the USSR was formed by Wittgenstein’s predilection for Russian poetry and literature of the nineteenth century, i.e., Tolstoy, Dostoevsky, and Pushkin. Analysing the development of Wittgenstein’s ideas on language in his Cambridge period, the author mentions the influence of N. Bakhtin and P. Sraffa. Also, the author touches upon the topic of the possibility of Marxism’s influence on Wittgenstein’s life and thought. (shrink)

I defend an analog of probabilism that characterizes rationally coherent estimates for chances. Specifically, I demonstrate the following accuracy-dominance result for stochastic theories in the C*-algebraic framework: supposing an assignment of chance values is possible if and only if it is given by a pure state on a given algebra, your estimates for chances avoid accuracy-dominance if and only if they are given by a state on that algebra. When your estimates avoid accuracy-dominance (roughly: when you cannot guarantee that other (...) estimates would be more accurate), I say that they are sufficiently coherent. In formal epistemology and quantum foundations, the notion of rational coherence that gets more attention requires that you never allow for a sure loss (or “Dutch book”) in a given sort of betting game; I call this notion full coherence. I characterize when these two notions of rational coherence align, and I show that there is a quantum state giving estimates that are sufficiently coherent, but not fully coherent. (shrink)

This article encourages a reconsideration of Christian sociology. It explains how deism makes a decisive impact in the theoretical foundations of the discipline. Dutch neocalvinistic philosophy in its North American immigrant setting after World War II issued a challenge which drew attention to the dogmas of deism implicit in sociology, but this challenge has not been met. Christian sociology, however, still retains its God-given vocation to find ways to encourage people everywhere to positively form complex differentiated social settings (...) in the Spirit of the Suffering and Glorified Messiah.

En el presente trabajo, expondremos uno de los problemas centrales de la filosofía spinoziana, que ha atravesado a gran parte de los pensadores occidentales, nombres tales como Gilles Deleuze o Gilbert Simondon, pero que, a partir del filósofo holandés, tuvo un desarrollo particular con una visión renovadora. Hacemos referencia a la noción de individuación, sus procesos generadores y la importancia que en ella tiene el concepto spinoziano de conatus. Procederemos a explicar este concepto y su función en el proceso de (...) individuación del ser humano, ya que, la noción de individuo se encuentra entrelazada a los conceptos spinozianos de potencia y conatus. Spinoza, a diferencia de la tradición clásica que predicaba la potencia de la divinidad, lo que hace es predicar la divinidad de la potencia, la naturaleza es Dios, naturaleza como potencia. // In this paper, we will discuss one of the central problems of Spinozian philosophy, which has affected many Western thinkers, such as Gilles Deleuze or Gilbert Simondon, but which, starting with the Dutch philosopher, had a particular development with a renewing vision. We refer to the notion of individuation, its generating processes and the importance that the Spinozian concept of conatus has in it. We will proceed to explain this concept and its function in the process of individuation of the human being, since the notion of individual is intertwined with the Spinozian concepts of potency and conatus. Spinoza, unlike the classical tradition that preached the potency of divinity, what he does is preach the divinity of potency, nature is God, nature as potency. (shrink)

A critical examination of the Reflection principle in Bayesian epistemology, and of the diachronic Dutch-book-style arguments that have been invoked to support Reflection and Conditionalization.

Winner of the American Philosophical Association’s 2019 Essay Prize in Latin American Thought | Western imperialism has received many different types of moral-political justifications, but one of the most historically influential justifications appeals to an allegedly universal form of human nature. In the early modern period this traditional conception of human nature—based on a Western archetype, e.g. Spanish, Dutch, British, French, German—opens up a logical space for considering the inhabitants of previously unknown lands as having a ‘less-than-human’ nature. This (...) appeal to human nature originally found its inspiration in the philosophy of Aristotle, whose ethical thought pervaded the work of European philosophers at the outset of the early modern period and the modern age of empire. Indeed some Spanish writers—most famously, Juan Ginés de Sepúlveda (b. 1494)—explicitly appealed to Aristotle’s moral-political philosophy in order to justify the conquest of the Americas in the early sixteenth century, for instance to justify war against the Aztecs and other indigenous peoples. At the time of European arrival, the Aztec civilization was easily the greatest in Mesoamerica—and yet the Europeans generally considered the Aztec people to be ‘barbaric,’ i.e. less-than-fully-human.

-/- In Plato's work the "Sophist", Socrates, who typically occupies a central position in Plato's dialogues, is assigned a supporting role. This has led some scholars to argue for a shift in Plato's oeuvre, where he distances himself from Socrates and introduces a new main protagonist. However, this new protagonist remains unnamed and is only identified by his social position as Xenos, indicating that he is an outsider and a stranger whose identity is ambiguous. In this article, I argue that (...) Plato's decision to leave the character unnamed serves to raise a first problem: the question of whether this stranger is a friend or an adversary of philosophy. At the beginning of the dialogue, Socrates employs a series of references to Homer to bring into play a second problem: the problem of disguise. The third problem, “What is a sophist?”, is attributed to the Xenos. This is the only problem that is explicitly developed and is, therefore, the most prominent in the dialogue. If we relate these three problems to each other, it becomes clear that they represent contradictory intuitions without providing us with a strict criterion for deciding which of these intuitions is correct. By presenting these problems in their entanglement without providing a way out, Plato invites his readers to think without making explicit what the outcome of this thinking should be. -/- [In Dutch: In de "Sofist" speelt Sokrates, vaak het meest prominente personage in Plato’s dialogen, alleen maar een bijrol. Dit heeft veel interpreten ertoe verleid om een breuk in het oeuvre van Plato te postuleren, waarbij Plato afstand zou nemen van Sokrates ten behoeve van een nieuw personage. Ik zal echter laten zien dat Plato er bewust voor kiest om dit nieuwe personage naamloos te laten en hem alleen aan te duiden via zijn sociale positie als xenos (vreemdeling). Hiermee roept Plato, zo zal ik betogen, impliciet een eerste probleem op: is deze naamlo- ze Xenos een vriend of een vijand van de filosofie? Aan het begin van de dialoog wordt er door Sokrates een tweede probleem in spel gebracht: het probleem van de vermomming. Het derde probleem — ‘wat is een sofist?’ — wordt toegeschreven aan de Xenos. Dit is het enige probleem dat expliciet wordt uitgewerkt en is dan ook het meest prominent aanwezig in de dialoog. Als we deze drie problemen op elkaar betrekken dan wordt duidelijk dat ze tegenstrijdige intuïties vertolken, zonder dat we een strikt criterium krijgen aangereikt om te beslissen welke van deze intuïties de juiste is. Door deze problemen in een nog niet ontwarde kluwen te presenteren, nodigt Plato zijn lezers uit tot denken, zonder expliciet te maken wat de uitkomst van dit denken zou moeten zijn.]. (shrink)

In the history of European philosophy and science, René Descartes is considered an author of a methodology of radical doubt, meditation, and the conception that explains the cause of human errors. But the course on internalization, knowledge of one's own Self, methodology of searching foundation of knowledge and conception of perfect reason have been formed already in the times of a Late Antiquity, particular by Augustine in his works “Soliloquies” and “Confession”, Boethius’s “The Consolation of Philosophy” and was (...) continued in the New age by Loyola’s “Spiritual exercises” and Teresa of Avila’s “The Interior Castle”. Therefore, Descartes could be rightfully considered rather the brilliant inheritor of this tradition than pioneer. To this chain of philosophers and theologians who were forerunners of Descartes’s theory of Radical doubt and especially problem of the source of human errors worth to add a new name – Hadewijch, the representative of medieval Dutch vernacular theology and her works “Visions” along with “Letters”. Precisely her point of view on cause of human errors, very close to the explanation have been given by Descartes in his IV Meditation. The aim of the research is to demonstrate common positions of Descartes’s and Hadewijch’s explanation of the nature of the errors. (shrink)

Rescorla (Erkenntnis, 2020) has recently pointed out that the standard arguments for Bayesian Conditionalization assume that whenever I become certain of something, it is true. Most people would reject this assumption. In response, Rescorla offers an improved Dutch Book argument for Bayesian Conditionalization that does not make this assumption. My purpose in this paper is two-fold. First, I want to illuminate Rescorla’s new argument by giving a very general Dutch Book argument that applies to many cases of updating (...) beyond those covered by Conditionalization, and then showing how Rescorla’s version follows as a special case of that. Second, I want to show how to generalise R. A. Briggs and Richard Pettigrew’s Accuracy Dominance argument to avoid the assumption that Rescorla has identified (Briggs and Pettigrew in Noûs, 2018). In both cases, these arguments proceed by first establishing a very general reflection principle. (shrink)

(text in Dutch) Mediated by the so-called Dream-organ ('Traumorgan') which opera composer Richard Wagner mentions in his writings, the author engages in a fictitious dialogue with Wagner. Their dialogue focuses on a few topics related to the conference theme 'Conflict and compassion' that were of concern to Wagner in his days and which have undergone some serious changes since his death. The author discusses with Wagner the 'death of tragedy', sexuality and desire after the sexual revolution, the attractivity of (...) musical genres like film and dance music, and the role of travel.

Hegel's reading of Hafez as part of his Berlin aesthetics lectures. The jargon of the prosaic world -/- This essay deals with Hegel's reading (Georg Wilhelm Friedrich Hegel, 1770 - 1831) of Hafez' poetry (Moḥammad Schams ad-Din Hafez Schirazi, around 1315 - 1390) during his lectures on the Aesthetics or Philosophy of Art at the University of Berlin (1820/21; 1823; 1826; 1828/29). Hegel's writings, Lectures on Aesthetics, were published from his remains by Heinrich Gustav Hotho (1802 - 1873) in (...) three volumes (1835 - 1838) and in a second edition from 1842 onwards. The posthumously published writings of Hegel are, considering the preserved archive material and the unreliable editing work by Hotho, a thoroughly complex research topic. Therefore, this problem area also forms the starting point of the present analysis of Hegel's reading of Hafez. -/- Within the framework of this essay, Hegel's categories of historical frameworks (Symbolic, Classical, and Romantic Art), especially that of the "Symbolic Art", are examined in his lectures on Aesthetics . This will do in three steps: starting with the current state of research, problematizing of Hegelian concepts in his Lectures on Aesthetics like "oriental Pantheism" or Vorkunst, ("the threshold of art" or "praeambula": T. M. Knox' translation, 1975, part I); extending the discussion by focusing on similarities and differences between Hegel's reading of Goethe (part II) and Hegel's reading of Hafez (part III) in his Berlin Aesthetics Lectures of the 1820's. For this purpose, material from Goethe's literary remains (II), as well as a masterpiece of Dutch painters van Eyck analyzed by Hegel (Ghent Altarpiece) during his lectures (III), will be included in the analysis and explored from an interdisciplinary and intercultural perspective. In doing so, Goethe's “Space of Experience and Horizon of Expectation” (Koselleck) in imitating Arabic script and calligraphy (II) is linked to Hegel's reading of Hafez during his Berlin lectures on aesthetics (III). Thus, a dialogue of cultures unfolds between poetry and philosophy. The main questions are: How does the German philosopher Hegel interpret and receive Hafiz's poetry in the context of German idealist philosophy as a topic of his lectures on aesthetics? What epistemological aspects can be gained from Hegel's reading of Hafez for a cultural studies analysis, especially regarding the history of the ideas? In addition to analyzing the historical aspects, the aim is also to uncover new perspectives in order to look with Hafez and Rumi at Hegel's problem child of ‘history’. Of particular interest are epistemological aspects and problems of reception and translation studies in sense of interdisciplinary and intercultural research (e. g. connected/entangled histories; boundary objects). Interculturality is understood in the context of the present essay as a cross-disciplinary theoretical framework in the sense of entangled histories research work interwoven with communication, aesthetic and cultural techniques approaches or resilience studies in a historical perspective.

I. Introduction Siris, Berkeley's last major work, is undeniably a rather odd book. It could hardly be otherwise, given Berkeley's aims in writing it, which are three-fold: 'to communicate to the public the salutary virtues of tar-water,'1 to provide scientific background supporting the efficacy of tar-water as a medicine, and to lead the mind of the reader, via gradual steps, toward contemplation of God.2 The latter two aims shape Berkeley's extensive use of contemporary natural science in Siris. In particular, Berkeley's (...) focus on what he calls fire (or aether or light) as a quasiuniversal 'cause' of natural change3 serves these purposes, for the 'activity' of the aether, in his view, can both explain the miraculous virtues of a certain medicine, i.e. tar-water, and reveal God's action and his divine order.4 Berkeley's corpuscular speculations, including his use of fire-theory, are not especially idiosyncratic as natural philosophy. In his theorizing, as Jessop and other have noted, he is heavily indebted to the work of Hermann Boerhaave, the Dutch chemist, botanist, and physician whose teachings were highly influential in mid-eighteenth century Britain.5 Boerhaave, along with other Dutch natural philosophers cited by Berkeley, assigned a central role in accounting for physio-chemical activity to fire, a subtle, insensible particulate substance, sometimes identified with light.

The present study aims to present a transcription and a commentary of three unpublished letters of the Dutch Cartesian philosopher Johannes de Raey, addressed to his former student Johannes Clauberg. Mainly containing suggestions concerning the defence of Cartesian philosophy and academic affairs, these letters, dating back to 1651, 1652 and 1661, bear witness of a steady friendship and of a certain cooperation in rebuking the critiques moved by Jacob Revius in his Statera philosophiae cartesianae and by Cyriacus Lentulus (...) in his Nova Renati Descartes sapientia, refuted in Clauberg’s Defensio cartesiana. According to these letters, this cooperation had to be kept secret, not to provoke the reaction of Leiden theologians. However, the violation of the correspondence of Clauberg and De Raey occasioned the edition of Lentulus’s book and the rise of the polemics over the new philosophy. Eventually, such cooperation is to be noticed also in some crypto-quotations between the edited texts of Clauberg and De Raey. (shrink)

As Ebbinghaus (1908) tells us in the opening words of his popular textbook of psychology, “psychology has a long past but only a short history.” In my opinion, there are three foundational moments in the history of psychology and, paradoxically, all three are moments of great advancement in biology. First, in the long past of psychology, psychology did not exist as such but was part of philosophy. It is extremely interesting to understand why it has been necessary, at one (...) point of time in the sixteenth century, to invent this field and to create a signifier – namely “psychology” – separate from philosophy, which enabled the field to distinguish itself from philosophy (Mengal, 2000/2001). In this century of religious violence, bare corpses lay everywhere and progresses in anatomy are major. In 1540, the German religious reformer Philippe Melanchthon publishes a book which comments the De anima of Aristotle and he completes the Aristotelian text with a long treaty of anatomy (Mengal, 2000/2001). On the basis of this new knowledge, Melanchthon attributes functions to the body which were previously reserved for the soul. The brain becomes the principal organ of sensory functions and displaces the heart as the seat of emotional life and of thought. To the Aristotelian position that all living beings, whether plant, animal, or human, to varying degrees possess a soul which organizes the body, Melanchthon opposes a dualistic anthropology which divides the human in body and soul. The two-dimensional “anthropologia” is articulated in “anatomia,” science of body, and “psychologia,” science of the soul. It is this new anthropology that is diffused into the world of the Reformation (Mengal, 2000/2001). The Dutch reformer Snellius (1594), for example, defines the body and the soul by their respective essential property: “The rational soul of man is the thought that, coupled with the body, completes man. (…) The physical things closer to natural bodies that move naturally, have an extension and for that reason occupy a space. (…) The faculty of the rational soul is the mind or will. Thought is the faculty of the soul to discourse and think about things which are and which are not.”1 (Snellius, 1594, pp. 26–27). It is as a philosopher that René Descartes proposes his dualist vision much in line with the reformist opinions. Descartes dissects animals and human cadavers and is familiar with the research on the flow of blood (Fuchs, 2001). He comes to the conclusion that the body is a complex device that is capable of moving without the soul, thus contradicting the Aristotelian doctrine of the soul. The metaphysical order, which states that the body exists by the soul, is broken. (shrink)
