Wittgenstein's House reads his two main philosophical texts, "Tractatus Logico-Philosophicus" and "Philosophical Investigations", in relation to an experience that intervened between them: his design and construction of the Stonborough-Wittgenstein house in Vienna. Arguing that the practice of architecture occupies not just a historical position between Wittgenstein's early and late philosophy but a conceptual position as well, the book demonstrates that Wittgenstein's practice of architecture constitutes a fundamental component in the development of his philosophy of language from its early to late phases.The book advances the radical proposition that the field in which architecture and philosophy operate includes linguistic and spatial practices. It develops innovative forms of interdisciplinary analyses to demonstrate that the philosophical positions put forth by Wittgenstein's two main works are literally unthinkable outside of their respective conceptions of space: the view from above in the early work and the view from within constructed by the late work.
