ESENCIALISMO Y ESPACIO CUALITATIVO

Abstract

This article states that there is a convergence between Quine's thesis on the progressive disappearance of the subjective criteria of resemblance (here referred to as the thesis of the dispensability of spacing of qualities) and Kripke and Putnam's essentialist notion of natural kinds. Convergence consists in substituting causal criteria for morphological criteria; making it explicit may result in certain minimum agreements for essentialism assessment. I will also sustain that the standard comprehension according to which Kripke and Putnam are committed with a nonhistorical concept of a species essence may be rebutted.
