This article reconstructs Kant's view on the existential import of categorical sentences. Kant is widely taken to have held that affirmative sentences (the A and I sentences of the traditional square of opposition) have existential import, whereas negative sentences (E and O) lack existential import. The article challenges this standard interpretation. It is argued that Kant ascribes existential import only to some affirmative synthetic sentences. However, the reasons for this do not fall within the remit of Kant's formal logic. Unlike traditional logic and modern standard quantification theory, Kant's formal logic is free from existential commitments

Although the notion of empiricism looms large in many histories of early modern philosophy, its origins are not well understood. This paper aims to shed light on them. It examines the notions of empirical philosopher, physician, and politician that are employed in a range of seventeenth- and eighteenth-century texts, alongside related notions (e.g. "experimental philosophy") and methodological stances. It concludes that the notion of empiricism used in many histories of early modern thought does not have pre-Kantian origins. It first appeared and became widely used in late eighteenth-century Germany, in the course of the early debates on Kant's Critical philosophy.

Many scholars claimed that, according to Immanuel Kant, some judgements lack a truth-value: analytic judgements, judgements about items of which humans cannot have experience, judgements of perception, and non-assertoric judgements. However, no one has undertaken an extensive examination of the textual evidence for those claims. Based on an analysis of Kant's texts, I argue that: (1) according to Kant, only judgements of perception are not truth-apt. All other judgements are truth-apt, including analytic judgements and judgements about items of which humans cannot have experience. (2) Kant sometimes states that truth-apt judgements are actual bearers of truth or falsity only when they are taken to state what is actually the case. Kant calls these judgements assertoric. Other texts ascribe truth and falsity to judgements, regardless of whether they are assertoric. Kant's views on truth-aptness raise challenges for correspondentist and coherentist interpretations of Kant's theory of truth; they rule out the identification of Kant's crucial notion of objective validity with truth-aptness; and they imply that Kant was not a verificationist about truth or meaning.

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.
