Logic, Value and Our Moral Claims
When we think about language, logic seems to be an intrinsic part of what we have in mind. It’s logic, after all, i.e., the rules of relations between expressions of thought as realized in language, that make any language intelligible. This seems so because, without such rules built into it, language could not do its job.
To the extent that language is about referring, either by describing or naming (i.e., using words to point out or point at things), logic (the rules by which we put our referring terms together to accomplish the foregoing in complex ways which succeed as communication) is indispensible. And so logic seems an indispensible element of any language that we recognize as a language.
Of course, language consists of more than just the complex process of asserting things about other things. It includes doing things like signaling and expressing our emotional states for the benefit of others (so they will see and react to those expressions) and it’s this aspect in our languages that we find, in various forms, in the broader animal kingdom of which we are a part. Language also includes other types of things we can do with our words such as voicing imperatives (do this, don’t do that) which seem to depend, at least in part on, our assertoric capabilities (the capacity to describe and name things). Language is plainly multi-faceted and at least one more thing we do with words, in the context of speaking a language, is to evaluate the things we make assertions about. Indeed, even the assertions themselves, when these are taken as referents (depictable elements in the world) in their own right, are subject to valuation by us.
Unlike logic, however, which we seem to take on faith, seeing little reason to trouble ourselves about justifying it as part of language, valuing appears to occupy a different niche in our thoughts about language and what we do with it . . . .
