Abstract: Spatial metaphors have peculiar prominence in accounts of rationality, such as in the phrase “space of reason” made prominent by Wilfrid Sellars and John McDowell. This article attempts to understand the potential of such comparisons of reason to space, taking Wittgenstein’s metaphor of “logical space” as exemplary. As Hans Blumenberg observes in his reading of Wittgenstein and in contrast to its stated aim, the account of “logical space” in the Tractatus does not achieve a final delimitation of reason. Wittgenstein’s discussion of different forms of rationality rather leads him to consider a plurality of spaces. Asking how these different spaces or fields of meaning can be congruent at all, Wittgenstein is led to consider the indeterminacy of space itself in contrast to the different localizations it allows.
