Immanuel Kant [SEP] Theory of perception
Kant defines his theory of perception in his influential 1781 work the "Critique of Pure Reason", which has often been cited as the most significant volume of metaphysics and epistemology in modern philosophy. Kant maintains that our understanding of the external world had its foundations not merely in experience, but in both experience and "a priori" concepts, thus offering a "non-empiricist critique of rationalist philosophy", which is what has been referred to as his Copernican revolution. Firstly, Kant distinguishes between analytic and synthetic propositions: An analytic proposition is true by nature of the meaning of the words in the sentence — we require no further knowledge than a grasp of the language to understand this proposition.
