Abstract

In a recent paper Copi has argued for the admission of the term “essence” into scientific terminology. His primary reason is that the increasing adequacy of scientific theories is evidence of a gradual approximation to the real essences of things. Copi is aware that the laws of modern science are not to be taken as formulations of essences. But, he claims, “that is an ideal towards which science strives… Centuries hence wiser men will have radically different and more adequate theories, and their notions will be closer approximations than ours to the real essences of things.”
