Wittgenstein in his early work viz. Tractatus argued that there is a common, essential, underlying structure that links logic, language and the world. He also argued about the need for an analysis of ordinary language in terms of a perspicuous symbolism that would display a one to one relationship between a proposition and a fact – when both of them are broken down to their simplest components – viz. to atomic propositions and atomic states of affairs. All propositions are ultimately (...) truth-functional combinations of atomic propositions – thus all language is resolvable to a unique constant. So for early Wittgenstein, though there is an apparent complexity and diversity of propositions still there lies a uniform, essential structure of truthfunctional propositions and that can be reduced to a single constant. And language to have a determinate sense must be ultimately based on objects – the absolutely simple logical atoms of the world. These objects imbibe their range of combination with other objects, which implies that any genuine propositions – however unusual and unconventional it may seem to be – must ultimately be constrained by the permissible range of combination of the objects. In this way early Wittgenstein sought to secure an essential metaphysics via an essential structure of language. However in Philosophical Investigations Wittgenstein attacked essentialism by rejecting the picture theory, and the search for commonality and uniformity. He denied essence, the universal, the common element present in all the objects of a class and accepted only an indeterminate and incomplete flow of the criss-crossing, the overlapping features. For him language is constituted by an ever expanding flow of uses, which he called language-games. The significance of the term ‘language-game’ lies in the fact that like games language too is not based on any ontology that would confer a common essence across all the widely divergent uses. Nor did Wittgenstein accept any hidden essence behind appearance. In PI the later Wittgenstein denied both analysis and essence and propagated description of usage and behaviours as the only method of philosophy. Later Wittgenstein will neither commit himself to ontological necessity, nor to necessity being a matter of scheme-relative propositions in the Quinean sense. For later Wittgenstein all attempts to establish essences, or the contrary exercises to relativise them to a particular set of presumptions, are themselves language-games – they boil down to usage and practices that do not rest on any foundation.

Nowadays, essentialism has obtained various senses and its extension reaches out over many branches of study who have some immediate connection with it. Socrates, Plato, Aristotle, Saul Kripke, Hilary Putnam and David Wiggins are the notable upholders of essentialism. The Essentialist movement which stemmed from the view that philosophy is a speculative study of Reality was temporarily suspended or stagnated by the spirited movement of the logical positivists like Moritz Schlick, Hans Reichenbach, Rudolf Carnap and A. J. Ayer. According to (...) these philosophers, philosophy is simply an activity of analysis of the fundamental concepts of ordinary language or of science or of any other discipline. Such concept—analysis—philosophers are called anti-essentialist. Here, I shall concentrate on the views of Aristotle. I shall discuss the doctrine of essence, natural kinds, real essence in favour of essentialism and also discuss W. V. O. Quine’s view as an anti-essentialist trend. At last I shall try to examine whether and to what extent an attack of essences reflects back certain essentialist commitments, which is to see what reasonable theory of essences can be eked out from the entire exercise.
