Show Summary Details


The ‘unity of reason’ is mentioned at several points in Kant's writings, but it is never systematically discussed or explained in any detail. Occasionally, this ‘unity’ seems something that we can take for granted. At other times, it appears to be a thesis that has just been implicitly established. However, for the most part it is presented as an extremely ambitious, all-encompassing research project that Kant feels he has to postpone until some indefinite time in the future. This chapter tries to disentangle these different ‘unities’ of reason, arguing that Kant was primarily concerned with the unity of the final philosophical system that reason as a unitary faculty seeks to produce, whereas the unity of reason in the sense of a unitary faculty of reason is taken for granted. The chapter focuses on some philosophically important features of Kant's critical theory of reason, reasoning and reasons in the two spheres.
