Frege’s conceptions of sense, truth, and falsehood, assertion, thought, the logical connectives, the laws of thought, and the laws of logic is described as Wittgenstein understood them. Wittgenstein’s criticisms of Frege’s conceptions as elaborated in the Tractatus and associated early writings are described and analysed. The criticisms are shown to be powerful and to undermine Frege’s conception of logic and the primary supports of his philosophy of logic.

Keywords: assertion; assumption and assertion sign; Frege; function theoretic logic; laws of logic; logic; logical connectives; sense and meaning (reference); the True and the False; Tractatus
