Kant and Sartre are two of the most significant figures in modern philosophy, and yet there has, until very recently, been little comparative research undertaken on them. Despite dealing with many shared philosophical issues, they have traditionally been taken to be too opposed to each other to render any search for possible parallels between their works a useful enterprise. Indeed, Sartre is often taken to be one of Kant’s most vocal critics in the literature, and as rather indebted to other major figures, such as Husserl and Heidegger. As a consequence, often, where comparative analysis has been done upon Kant and Sartre, the emphasis has been on their differences, rather than on their similarities. However, as recent research has begun to show, the story is not that straightforward and there is much to be explored with regard to parallels between Kant and Sartre. Baiasu has characterised Sartre’s relation to Kant as one of an “anxiety of influence” – Sartre desires to explicitly distance himself from Kant, but this obscures some deeper underlying parallels between them1. Such parallels can form a foundation for productive dialogue, more widely, between the schools of Kantian “Critical philosophy” and existentialism2

How do we form concepts like those of three, bicycle and red? According to Kant, we form them by carrying out acts of comparison, reflection and abstraction on information provided by the senses. Kant's answer raised numerous objections from philosophers and psychologists alike. "Kant e la formazione dei concetti" argues that Kant is able to rebut those objections. The book shows that, for Kant, it is possible to perceive objects without employing concepts; it explains how, given those perceptions, we can form categories and empirical concepts; and it argues that theories like Kant's - abstractionist theories of concept formation - are more plausible than is often assumed.

Several recent studies of early modern natural philosophy have claimed that corpuscularism and experimental philosophy were sharply distinct or even conflicting views. This chapter provides a different perspective on the relation between corpuscularism and experimental philosophy by examining Domenico Guglielmini’s ‘Philosophical Reflections’ on salts (1688). This treatise on crystallography develops a corpuscularist theory and defends it in a way that is in line with the methodological prescriptions, epistemological strictures, and preferred argumentative styles of experimental philosophers. The examination of the ‘Reflections’ shows that early modern philosophers could consistently endorse, at the same time, corpuscularism and experimental philosophy.

This chapter discusses the relation between Kant’s views on the foundations of syllogistic inference in ‘The False Subtlety of the Four Syllogistic Figures’, the views of eighteenth-century German authors who wrote on syllogism, and the conception of metaphysics that Kant developed in 1762-1764. Kant’s positions are, on the whole, rather original, even though they are not as independent from the intellectual context as Kant’s later, Critical philosophy. Despite Kant’s polemical tone, his views on syllogism are not primarily motivated by polemical purposes. They are strongly influenced by his views on the method of metaphysics.

In his essay against Eberhard, Kant denies that there are innate concepts. Several scholars take Kant’s statement at face value. They claim that Kant did not endorse concept innatism, that the categories are not innate concepts, and that Kant’s views on innateness are significantly different from Leibniz’s. This paper takes issue with those claims. It argues that Kant’s views on the origin of the intellectual concepts are remarkably similar to Leibniz’s. Given two widespread notions of innateness, the dispositional notion and the input/output notion, intellectual concepts are innate for Kant no less than for Leibniz.
