This essay-a thesis accepted for the Cornell doctorate-consists of two parts, the first historical, the second expository and critical. Part I. traces the influences that led to the acceptance of a tripartite division of mind (intellect, feeling, will) in place of the older bipartite division. It also shows that Kant's original intention, in writing a third Critique, was to establish a priori principles of the new faculty of feeling; and argues that the combination of the Critiques of Taste and of (...) Teleology into a single Critique of Judgment was due to the fact that both alike were seen to centre round the idea of purposiveness. Part II indicates the need of mediation, formal and real, between the two Critiques of theoretical and of practical philosophy. The real opposition between them is to be found, primarily and chiefly, in the admission or rejection of the concept of freedom. By an elaborate analysis of Kant s theory of the beautiful, and a discussion of his use of the principle of teleology as applied to organic nature, the author is able to make it clear that the Critique of Judgment effects the desired real reconciliation. A concluding section suggests that Kant would have allowed objective validity to the teleological principle, had not the table of categories in the K. d. r. V. been already complete. -Mind [1898].
