This book addresses fundamental problems of knowledge.""Eternal Possibilities: A Neutral Ground for Meaning and Existence"" builds on David Weissman's earlier ""Dispositional Properties"" and makes a signal contribution to the study of metaphysics. Here, broadening and enriching the point of view adopted in his earlier work, Weissman cites and criticizes a large number of theories proposed by authors from Plato to Wittgenstein and others exploring language theory and metaphysics.Students of Wittgenstein will be especially interested in Mr. Weissman's critical examination of Wittgenstein's claim in the ""Tractatus"" that possibilities are the facts for logic. Weissman proposes a modal theory of properties: they exist in the first instance as possibilities. He argues that a sentence is meaningful if it signifies a property or complex of properties existing as a possible, and true if that possible is instantiated. The status of possibilities and their relation to actual states of affairs are considered in detail.
