Wittgenstein: The Only Genius of the Century?

Thomas Nagel provides a brief summary of Wittgenstein's thought, both early and late, for the general public. Summarizing the late Wittgenstein, Nagel writes: "The beginning, the point at which we run out of justifications for dividing up or organizing the world or experience as we do, is typically a form of life. Justification comes to an end within it, not by an appeal to it. This is as true of the language of experience as it is of the language of physical objects or mathematic. Experience cannot be regarded as the absolute given on which the structure of the world is based, for the categories of experience itself—what constitutes sameness, difference, and structure in that domain—are as much dependent on the interpersonal responses of a communal form of life as any other conceptual or linguistic domain."
