How we read Kant's Critique of Pure Reason has a huge influence on how convincing we find the parts of which it is composed. This thesis will argue that by taking its arguments and concepts in isolation we neglect the unifying architectonic method that Kant employed. Understanding this text as a response to a single problem, that of the possibility of synthetic a priori judgement, will allow us to evaluate it more fully. We will explore Kant's attempts to relate the (...) a priori and the synthetic in the Introduction, Metaphysical Deduction and Analytic of Principles of the Critique of Pure Reason. Having developed this reading at length we will be able to reassess Kant's relation to the work of Gilles Deleuze. Deleuze's critique of Kant and his tendency to make selective use of his work has so far characterised their relations. However, by reading Kant's Critique of Pure Reason in terms of its unifying method we will open up a new means of relating these two thinkers. Whilst Deleuze rejects many key Kantian concerns and concepts he embraces his methodological concern with the ability of problems to unify our thought. The problem-setting and forms of argument that emerge within Kant's architectonic method will be related to Deleuze's account of experience. This thesis will contribute to both Kant and Deleuze studies on the basis of the reading of the Critique of Pure Reason it will present. By showing how Kant's text is to be read as a whole we will be able to challenge the conclusion that the arguments he makes ultimately rely upon a notion of 'subjective origin'. The problem of accounting for 'the actual' through its relation to 'the virtual' in Deleuze's thought will be re-assessed on the basis of his newly established relation with Kant. Understanding Kant's method in the Critique of Pure Reason will be shown to strengthen both his own account of experience and that offered by Deleuze. (shrink)
