plural mentaleses · alternative Mentalese
- uncountableusuallyhuman sciencesA hypothetical non-verbal language in which concepts are represented in the mind.First known use 1960s
The concept of a proposition as something that can be expressed by sentences in both Mentalese and, say, English is an analogical extension of the concept of a proposition as something that can be expressed by sentences in both English and German.

Translationists are said to treat the coding of thoughts in ‘Mentalese’, whose structure is already known, into a natural language, just like translating a natural language, say Russian, in terms of another known language, say English (G 282). Incorporationists point out the circularity of (36b) because Mentalese, supposed to be intrinsically intelligible, is just English or some other variety of a natural language, and the translation maneuver only postpones the problem, [...]

If it is learned, then what is it related to in the preceding mentaleses? To avoid endless regress, [Jerry] Fodor postulates an internal language that is innate, a claim that he himself calls "horrendous" and "scandalous," yet inescapable.

Or does language itself play a role in the formation of our thought? The question is called critical, since a positive response to the latter (language does play a role) would call into question the assumption that all meaning is reducible to mentalese.
1990, Patrick de Gramont, “The Problem of Representation”, in Language and the Distortion of Meaning (Psychoanalytic Crosscurrents), New York, N.Y.; London: New York University Press, →ISBN, page 53One suggestion is that there is a de facto correlation between words or sentences of natural language and expressions of mentalese and between the logical relations among the former and the causal relations among the latter. This is a curious idea. The alleged correlation is not empirically grounded.

We should more properly, in the context of a thesis of massive mental modularity, talk about languages of thought, or Mentaleses.
