 In practice, LOT theorists usually adopt a more specific view of the compositional semantics for Mentalese. They claim that Mentalese expressions have    logical form (Fodor 2008: 21). More specifically, they claim that Mentalese contains analogues to the familiar logical connectives (and, or, not, if-then, some, all, the). Iterative application of logical connectives generates complex expressions from simpler expressions. The meaning of a logically complex expression depends upon the meanings of its parts and upon its logical structure. Thus, LOT theorists usually endorse a doctrine along the following lines:
