Taking into account significant developments in the metaphysical thinking of E. J. Lowe over the past 20 years, More Kinds of Being:A Further Study of Individuation, Identity, and the Logic of Sortal Terms presents a thorough reworking and expansion of the 1989 edition of Kinds of Being. * Brings many of the original ideas and arguments put forth in Kinds of Being thoroughly up to date in light of new developments * Features a thorough reworking and expansion of the earlier work, rather than just a new edition * Reflects the author's conversion to what he calls 'the four-category ontology,' a metaphysical system that takes its inspiration from Aristotle * Provides a unified discussion of individuation and identity that should prove to be essential reading for philosophers working in metaphysics.
