Philosophicial Investigations

This volume presents the original German/English edition of Wittgenstein's Philosophical Investigations - one of the most influential philosophical works of the twentieth century.
The last product of intensive work by Wittgenstein during the period 1929-49, Philosophical Investigations explores the concepts of meaning; of understanding; of propositions; of logic; of states of consciousness; and many other topics. Wittgenstein subjects the approach of his early work, the Tractatus, to penetrating criticism and analysis.
It is essential reading for all students of philosophy.
