Context

““philosophical propositions”, but to make propositions clear. Philosophy should make clear and delimit sharply the thoughts which otherwise are, as it were, opaque and blurred. 4.1121 OGD [→GER | →P/M] Psychology is no nearer related to philosophy, than is any other natural science. The theory of knowledge is the philosophy of psychology. Does not my study of sign-language correspond to the study of thought processes which philosophers held to be so essential to the philosophy of logic?” source
