Abstract
If the slogan "No entity without identity" might be said to encapsulate the new essentialism, it has in any case been felt to serve the working ontologist as a powerful tool for ruling out certain dubious entities. The first half of Baruch Brody’s book consists in a radical "critique of this whole philosophical tradition," as it is seen to be "based upon a fundamental erroneous assumption," namely that "the truth-conditions of claims concerning identity vary as the type of entity in question varies." In fact no such parochial identity conditions need be invoked according to Brody, seeing that the Principle of the Identity of Indiscernibles will suffice to define identity in omnibus fashion across the board, even to the extent of being "understood by those who want to learn the meaning of ‘identity'."
