In Chapter 8 of Kant’s Critique of Pure Reason and the Method of Metaphysics, one of Gabriele Gava’s aims is to argue that Kant’s critique of Wolff’s dogmatic method has two levels: one directed against Wolff’s metaphilosophical views and one attacking his actual procedures of argument. After providing a brief summary of the main claims Gava makes in Chapter 8 of his book, in this paper I argue two things. First, I argue against Gava’s claim that the two forms of (...) dogmatism he distinguishes between are incompatible. Second, I suggest, contrary to Gava, that Kant’s critique of these two forms of dogmatism both operate on the metaphilosophical level in the sense that they both target the dogmatist’s beliefs or theory about the method they take themselves to be following.

In this chapter I offer an account of the nature, scope, and significance of Wolff’s claim that human beings have a duty to cognize moral good and evil. I illustrate that Wolff conceives of this duty as requiring that human beings both acquire distinct cognition of good and evil as well as avoid ignorance and error. Although Wolff intends for the duty to be quite demanding, he restricts its scope by, among other things, claiming it primarily concerns those who have (...) the skills, circumstances, and opportunity to acquire such cognition. Wolff calls these individuals the ‘inventors’ of the truths of morality and he considers himself to be such an inventor. I argue that part of the significance of this duty lies in the fact that Wolff conceives of himself as living up to it by writing the German Ethics, thereby sharing the knowledge he has ‘invented’ with others.

Why does Kant say that a “skeptical satisfaction of pure reason” is “impossible” (A758/B786)? I answer this question by giving a reading of “The Discipline of Pure Reason in Respect of Its Polemic Employment.” I explain that Kant must address skepticism in this context because his warning against developing counterarguments to dogmatic attacks encourages a comparison between the critical and the skeptical methods. I then argue that skepticism fails to “satisfy” [befriedigen] reason insofar as it cannot “pacify” reason’s tendency to (...) go beyond its own boundaries. The skeptical method reveals the past failures of dogmatic metaphysics but cannot rule out future successes. Only critical knowledge of reason’s proper bounds can do this, thereby pacifying our restless reason. I close by arguing that Kant’s discussion implies that a skeptic must feel dissatisfied with her renunciation of metaphysics, and that this dissatisfaction can lead her to take interest in Kant’s critical philosophy.

Are psychiatric disorders natural kinds? This question has received a lot of attention within present-day philosophy of psychiatry, where many authors debate the ontology and nature of mental disorders. Similarly, historians of psychiatry, dating back to Foucault, have debated whether psychiatric researchers conceived of mental disorders as natural kinds or not. However, historians of psychiatry have paid little to no attention to the influence of (a) theories within logic, and (b) theories within metaphysics on psychiatric accounts of proper method, and (...) on accounts of the nature and classification of mental disorders. Historically, however, logic and metaphysics have extensively shaped methods and interpretations of classifications in the natural sciences. This paper corrects this lacuna in the history of psychiatry, and demonstrates that theories within logic and metaphysics, articulated by Christian Wolff (1679-1754), have significantly shaped the conception of medical method and (psychiatric) nosology of the influential nosologist Boissier De Sauvages (1706-1767). After treating Sauvages, I discuss the method of the influential nosologist William Cullen (1710-1790), and demonstrate the continuity between the classificatory methods of Sauvages and Cullen. I show that both Sauvages and Cullen were essentialists concerning medical diseases in general and psychiatric disorders in particular, contributing to the history of conceptions of the ontology and nature of mental disorders.

There is a tension in Emilie Du Châtelet’s thought on mathematics. The objects of mathematics are ideal or fictional entities; nevertheless, mathematics is presented as indispensable for an account of the physical world. After outlining Du Châtelet’s position, and showing how she departs from Christian Wolff’s pessimism about Newtonian mathematical physics, I show that the tension in her position is only apparent. Du Châtelet has a worked-out defense of the explanatory and epistemic need for mathematical objects, consistent with their metaphysical (...) nonfundamentality. I conclude by sketching how Du Châtelet’s conception of mathematical indispensability differs interestingly from many contemporary approaches. (shrink)

Famously, in the essay Inquiry Concerning the Distinctness of the Principles of Natural Theology and Morality (Prize Essay), Kant attempts to distance himself from the Wolffian model of philosophical inquiry. In this respect, Kant scholars have pointed out Kant’s claim that philosophy should not imitate the method of mathematics and his appeal to Newton’s “analytic method.” In this article, I argue that there is an aspect of Kant’s critique of the Wolffian model that has been neglected. Kant presents a powerful (...) attack of the idea that philosophy should proceed through the analysis of concepts and argues that we should give up the aim of arriving at “complete” concepts as one of its fundamental desiderata. Importantly, this attack of philosophy conceived as conceptual analysis is distinctive and original if one compares it with Kant’s critique of analysis in the Critique of Pure Reason, which rests on the idea that analysis is insufficient to ground substantial metaphysical truths. I also make an additional point: Scholars have debated whether the appeal to Newton’s analytic method involves a form of empiricism. I submit that this debate is ill-conceived because Kant uses a notion of “given concepts” that is indeterminate with respect to their a priori or a posteriori status. (shrink)

In this contribution, we first discuss the aspects of the analytic method conceived by Kant in the Deutlichkeit that differentiate it from the Wolffian method and relate it to the Newtonian method. Compared to the philosophical tradition, the task of analysing concepts appears profoundly changed. Since Kant aims philosophy towards the world, he considers concepts as something given and intends to discern their characteristic marks by observing their usual applications. Although Kant abandons any attempt to define concepts nominally, he still (...) gives great relevance to words to the extent that concepts, according to him, acquire their meaning in the linguistic usage. We will also point out how for Kant the linguistic usage makes the analysis of concepts anything but easy and how a hermeneutic process is necessary for its completion. In distinguishing philosophical signs from mathematical signs, Kant provides the semiotic reasons that underlie his recourse to hermeneutics. (shrink)

The eighteenth-century German rationalist tradition is, broadly speaking, committed to (what I call) ‘the principle of rational cognition’: the grounded must be rationally cognizable from its sufficient ground. Whereas the prevailing view takes the fundamental challenge to rationalist paradise to stem from the principle of sufficient reason, I argue that it instead stems from this principle: How is it possible to rationally cognize anything at all from its ground? By investigating the opposing responses of two of Leibniz’s most influential immediate (...) successors, Christian Wolff and Christian Crusius, we find no easy way to remain in rationalist paradise.

In this paper, I consider whether a reading of Kant's solution to the Third Antinomy can offer material for devising a new model of transcendental argument. The problem that this form of argument is meant to address is an antinomy between two apparently contradictory claims, q and ¬q, where we seem equally justified in holding both. The model has the following form: p; q is a necessary condition of p; the only justification we have for q is that it is (...) a necessary condition of p; p is justified only in domain X (where X is a domain of objects of cognition); therefore, q is justified only in domain X. Because the argument shows that our justification for q is valid only in X, it also establishes that there is conceptual space to hold ¬q outside of X. (shrink)

This article examines Paul Guyer’s claim that we should attempt to ground the principle of religious freedom on the basis of Kant’s arguments for religious liberty. I problematise Guyer’s suggestion by investigating a hypothetical ‘dogmatic conflict’ between a scientifically and a religiously grounded belief. I further suggest that considering Christian Wolff’s philosophy might provide us with an approach which shares the benefits that Guyer identifies in Kant, while at the same time avoiding the issues Kant might run into that result (...) from the occurrence of the dogmatic conflict. I start by providing a background to Wolff’s philosophy and explaining the notion of the dogmatic conflict. Then I present a potential contemporary case of the dogmatic conflict and try to see how it would be dealt with based on Guyer’s proposal. Finally, I consider what a Wolffian solution would look like, arguing that Guyer’s project might benefit from considering Wolff. (shrink)

This article reveals the critical content of the idea of scientific revolution in Wolff's philosophy and shows Leibniz's contribution to its formation. Although Wolff's goal was to reform the method of philosophizing on the model of Euclid's geometry, which was based on the Cartesian idea of achieving certainty by clarifying concepts, this clarification Wolff in the sense of Leibniz sees in such an analysis of concepts that would accurately establish a connection between them and show the possibility of the object (...) that expresses this concept. Wolff sees the critical meaning of his method in the fact that by analyzing the concepts to link all concepts and statements into a single system, which was based on consistent grounds and would not contain unproven propositions. This would, according to Wolf, remove from philosophy all the concepts, the objects of which were not possible, and statements that could not be proved. Leibniz's idea of concept analysis also formed the basis of his notion of philosophy as the science of the possible. The critical meaning of this concept of philosophy in Wolff, as in Leibniz, was to limit the subject of philosophy only to the realm of the possible. Although the main critical ideas underlying Wolff's philosophical system were formulated by Leibniz, Wolf's system was still the fruit of his genius. Many of his critical ideas were groundbreaking and had a marked influence on the further development of philosophy. These include, first of all, the requirement to preface the construction of a system of philosophy with research the cognitive abilities of the human mind. However, his attempts to build a universal system of knowledge led to the leveling of the critical content of some of Leibniz's demands, which led to the accusation of him and Leibniz of atheism and fatalism.
