The paper offers a new account of Spinoza's conception of “substance”, the fundamental building block of reality. It shows that it can be demonstrated apriori within Spinoza's metaphysical framework that (i) contrary to Idealist readings, for Spinoza there can be no substance that is not determined or modified by some other entity produced by substance; and that (ii) there can be no substance (and hence no being) that is not a thinking substance.

In the first part of the paper I reconstruct Kant’s proof of the existence of a ‘most real being’ while also highlighting the theory of modality that motivates Kant’s departure from Leibniz’s version of the proof. I go on to argue that it is precisely this departure that makes the being that falls out of the pre-critical proof look more like Spinoza’s extended natura naturans than an independent, personal creator-God. In the critical period, Kant seems to think that transcendental idealism (...) allows him to avoid this conclusion, but in the last section of the paper I argue that there is still one important version of the Spinozistic threat that remains. -/- .

Although Deleuze’s work on Spinoza is widely known, it remains poorly understood. In particular, Deleuze’s interpretation of Spinoza’s immanentism has not been treated sufficient care; that is, with an eye to the context of its elaboration and the way in which it gradually takes on different characteristics. With this paper, I offer a synoptic analysis of Deleuze’s views on immanence in Spinoza and examine how these change over the course of Deleuze’s career. There are three ascending stages here: a first (...) one, where Deleuze’s attention is drawn to more recognizable issues in understanding Spinoza’s views on the deep metaphysical structure of reality; a second, more experimental one, where Deleuze questions what it means to be a reader of Spinoza in light of Spinoza’s theory of the body and affects; and a third, particularly iconoclastic stage, where Deleuze develops the theory of “the plane of immanence” as a way of articulating a meta-philosophical story about the place of non-philosophy at the heart of all philosophy. I trace each of these accounts, tie them together to tell a coherent and comprehensive narrative, and show what may be learned from this Spinoza that Deleuze portrays as drunk on immanence. (shrink)

There is little doubt that Salomon Maimon was both highly respected by, and highly influential upon, his contemporaries; indeed, Kant himself referred to Maimon as the best of his critics. The appraisal and reformulation of the Kantian project detailed in Maimon’s Essay on Transcendental Philosophy played a significant role in determining the criteria of success for post-Kantian philosophy, and was thus crucial to the early development of German Idealism. Key aspects of Maimon’s transcendental philosophy remain, however, relatively obscure. In particular, (...) it remains unclear to what degree Maimon’s skepticism is internal to the Kantian framework, and how this skepticism is related to Maimon’s so-called dogmatic rationalism. The central aim of this project is to present Maimon’s as a distinct form of post-Kantian skepticism: one which poses significant problems for Kant’s theoretical project and which motivates a reformulation of the critical framework. In Kant’s eyes, pre-Kantian forms of skepticism are insufficiently critical insofar as they involve a commitment to transcendental realism. By contrast, I argue that Maimon’s skepticism does not involve a commitment to transcendental realism and that it strikes at the heart of Kant’s critical project insofar as it constitutes what I term ‘critical’ as opposed to merely ‘empirical’ skepticism. I further argue that Maimon’s rationalism provides the materials for a response to this form of skepticism. This thesis contributes to contemporary debates in the history of philosophy concerning the nature of Maimon’s coalition system and its relation to German Idealism, but also provides an alternative perspective on contemporary problems in the philosophy of perception concerning, in particular, the possibility of non-conceptual intentional content.
