Continuing the historical overview of conceptions of language in the 20th century, this course revolves around the relations between philosophical attitudes towards truth and meaning and fundamental ideas of the essence of philosophy, its conditions of possibility and its limits. The term opens with three philosophers whose main body of work was written around the 1940s and 1950s – the Later Wittgenstein, W.V.O. Quine and John Austin; it continues by presenting a comparison between two philosophers whose main contributions were written in the 1970s and 1980s – Donald Davidson and M.A.E. Dummett; we shall then divert for a brief encounter with Ferdinand de Saussure’s structuralism, in order to finish the term with Jacques Derrida’ post-structuralist conception of language.
