Abstract: The main concern of this article will be to discuss the reasons that led Wittgenstein to give up his earlier theory of meaning as advocated in the Tractatus.There is a specific problem relating to colour predicates, which initially led Wittgenstein to change his theory. As he realizes, his notion of elementary propositions which provide the foundation for his earlier theory of meaning, cannot be retained. It is thus felt that the problem posed by elementary propositions signifies the inadequacy of the earlier theory of meaning. On this consideration, Wittgensteins analysis of colour predicates assumes a paramount importance in the middle phase (during the period before investigation) of his philosophy. In this changed perspective, propositions are considered not in isolation, as in the case of elementary propositions, but as a system. Different propositions form a system of propositions. The idea of system of propositions…. has a lasting impact on the final stage of Wittgensteins theory of meaning. In fact, his main attempt to explain meaning in the light of Language-game as proposed in the Investigation can be shown to be a full-blown expression of the middle stage of his philosophy. In this discussion we will first see the problem of elementary proposition and second, Wittgensteins idea of a system of proposition. Finally, I will explain some important points relating to this issue. In the present discussion the above mentioned points will be discussed with reference to Wittgenstein Philosophical Remarks.
