Abstract

The subject of this paper is the notion of 'imponderable evidence', employed on a few occasions by the later Wittgenstein. Our perception of others' feelings, thoughts and emotions, Wittgenstein observes, is ordinarily guided by an imponderable evidence, which, while remaining unmeasurable and ultimately ungraspable, gives us access to an immediate-yet fallible-form of understanding. This understanding, I will argue, is essentially qualitative. Section 1 of the paper introduces the issue through the examination of some remarks on how our attitude towards living beings differs from our attitude towards objects. Sections 2 and 3 present the notion of imponderable evidence in the framework of Wittgenstein's approach to the philosophy of psychology and his remarks on aesthetic judgment. In section 4, I will turn to Dewey's conception of 'qualitative thought' as an aid to clarify further the sense of Wittgenstein's terminology. The final section concludes on why philosophers should care about the qualitative dimension of human existence.
