Abstract

This book’s purpose is to examine the source of semantic facts—broadly, to explain why our words have the meanings they do. Cresswell takes this explanation to lie in a complicated web of causal interactions on which semantic facts supervene. He makes three main claims about these causal interactions: the causation involved is best analyzed by Lewisian counterfactuals, themselves analyzed by possible worlds; they are so complicated as to preclude reduction of semantic facts to nonsemantic ones; and the lack of a reduction should not worry us. Key subsidiary discussions include arguments that makes plausible the success of possible-worlds semantics and that holds because our knowledge of semantic facts is “direct.”
