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.
