Reid's Account of Judgment and Missing Fourth Kind of Conception

Abstract

According to Thomas Reid, every act of mind is accompanied by a conception of its object. For instance, he holds that the thing one conceives in an act of perception is always an individual thing that exists, and that the thing one conceives in an act of judgment is the thing expressed by the proposition judged. However, Reid never is clear about what kind of thing is expressed by a proposition; neither is it clear from the existing literature on Reid. What he says about judgments, propositions, and general conceptions together suggests four distinct candidates. But I will argue that each of these candidates either fails to have sufficient textual support, or leads to absurd conclusions (such as that we conceive semi-existent things). In conclusion, I argue that while Reid does not offer an account of the kind of conception accompanying judgments, his writings leave the matter open.
