However, it seems that any perceived conflict between conceptual semantics and logical semantics can be resolved by noting that these two brands of semantics are quite different enterprises with quite different purposes. Certainly it is entirely appropriate for conceptual semantics to focus on the mapping from language to symbolic structures (in the head, realized ultimately in terms of neural assemblies or circuits of some sort), and on the functioning of these structures in understanding and thought. But logical semantics, as well, has a legitimate role to play, both in considering how words (and larger linguistic expressions) relate to the world and how the symbols and expressions of the internal semantic representation relate to the world. This role is metatheoretic in that the goal is not to posit cognitive entities that can be computationally manipulated, but rather to provide a framework for theorizing about the relationship between the symbols people use, externally in language and internally in their thinking, and the world in which they live. It is surely undeniable that utterances are at least sometimes intended to be understood as claims about  things, properties, and relationships in the world, and as such are at least sometimes true or false. It would be hard to understand how language and thought could have evolved as useful means for coping with the world, if they were incapable of capturing truths about  it.
