Explanatory reliance on such essentially first-personal phenomena is a necessary condition of adoption of a form of solipsism, but it is not sufficient.


both unique and irreducible about, say, the ‘I’, me, myself, my ego, my subjectivity, or my experience. Solipsistic theories, that is, stress what is. Broadly speaking a method, or doctrine, or point of view is solipsistic to the extent that it assigns a fundamental, irreducible, and asymmetrical role to subjective phenomena of the kind that are normally indicated by use of the singular form of the first person pronoun. The term ‘solipsism’ derives from the Latin solus ipse, meaning oneself alone. I will then discuss the epistemic status of inner speech, explaining how inner speech utterances exhibit a variety of different epistemic qualities, from utterances that self-constitutively determine their own truth values to the tendency of some linguistic phenomena to misguide and even deceive ourselves about the contents of our own minds. I will argue that a significant portion of our thoughts (namely, our conscious propositional thoughts) occur through inner speech and, consequently, that this vehicle for conscious thought provides the basis for substantial aspects of our awareness and understanding of our own minds. Inner speech is the experience of articulated natural language phenomena through internal auditory images and sub-vocal assertion, typically with phenomenal properties similar to one’s own voice, as if one is silently speaking to oneself.1 In this chapter, I will discuss and analyze the nature of this inner speech and the roles it plays in introspection. This phenomenon is known as inner speech. Reflections come and go in the form of linguistic expressions, whether we are thinking about dinner plans, mulling over a philosophical debate, or rehearsing a discussion with another person. People commonly report an internal stream of words constituting their own private thoughts.
