Quine and Davidson are among the leading thinkers of the twentieth century. Their influence on contemporary philosophy is second to none, and their impact is also strongly felt in disciplines such as linguistics and psychology. This is the first book devoted to both of them, but also the first to question some of their basic assumptions. Hans-Johann Glock critically scrutinizes their ideas on ontology, truth, necessity, meaning and interpretation, thought, and language, and shows that their attempts to accommodate meaning and thought within a naturalistic framework, either by impugning them as unclear or by extracting them from physical facts, are ultimately unsuccessful. His discussion includes interesting comparisons of Quine and Davidson with other philosophers, particularly Wittgenstein, and also offers detailed accounts of central issues in contemporary analytic philosophy, such as the nature of truth and of meaning and interpretation, and the relation between thought and language.
