Soto, part 1, chapter 5, sole lecture, note 2, thus defines a term: a sign constituting a categorical proposition. Observe that a categorical proposition is simple, as in Peter is white. Other propositions, however, are composed of one complete proposition, other terms, and a union; people commonly call them hypothetical propositions. For example, in Peter is white is a proposition, Peter is white is the subject, proposition is the predicate, and the second is is the union. With this established, I first object to Soto because his definition is incomplete: it does not apply to the parts of a hypothetical proposition, which truly are terms. I prove that it does not apply: Soto says that a term is constitutive of a categorical proposition, but this is not constitutive of a hypothetical proposition, since distinct propositions have distinct constituents. Therefore it does not apply to a constituent of a hypothetical proposition.
