Questions on Wittgenstein, first published in 1988, presents a selection of nine essays investigating a matter of vital philosophical importance: Wittgenstein's relationship to his Austrian predecessors and peers. The intention throughout is to determine the precise contours of Wittgenstein's own thought by situating it within its formative context. Professor Haller has spent his career exploring these themes, and is one of the foremost authorities on both Wittgenstein and contemporary Austrian philosophy.
