 The standard response is to deny that ordinary thinkers represent Mentalese words as having denotations (Bach 1987; Fodor 1975: 66–79). Mentalese is not an instrument of communication. Thinking is not “talking to oneself” in Mentalese. A typical thinker does not represent, perceive, interpret, or reflect upon Mentalese expressions. Mentalese serves as a medium within which her thought occurs, not an object of interpretation. We should not say that she “understands” Mentalese in the same way that she understands a natural language.
