ABSTRACT. For Wittgenstein, all aspects of the human mind are inescapably dependent upon the use of language. A cartesian view would maintain that thoughts and representation are possible without language, but Wittgenstein does not agree. In this paper I will describe Wittgenstein's theories of consciousness and representation. One of the central goals for Wittgenstein was to account for meaning. Wittgenstein offers two accounts of human consciousness. I will describe the early view, which was contained in his Tractatus Logico-Philosophicus. I will then explain his later thoughts. Although Wittgenstein changed his mind and refuted his early work, there is a central claim in all of Wittgenstein's work.
