The Project for a New Philosophy

Abstract

Moore made his philosophical discoveries, well known from Principia Ethica and Philosophical Studies, step by step. In the summer of 1895 he spent five weeks in Tubingen, Germany, attending Otto Crusius’s lectures on Plato, and Christoph Sigwart’s lectures on Kant.1 The effect of this visit was that Kant became Moore’s philosophical ‘indoctrinator in default’. This is clearly to be seen in his two Dissertations (1897, 1898a), which investigated Kant’s ethics. Roughly, Moore borrowed from Kant some elements of philosophical logic which he revised radically.
