Logic I, Lesson 1: Terms and Propositions

From Aristotle's Categories, 2 [explanatory notes in brackets]:

Forms of speech are either simple* [i.e., terms] or composite [i.e., propositions or judgments]. Examples of the latter are such expressions as 'the man runs', 'the man wins'; of the former 'man', 'ox', 'runs', 'wins'.

[*NB. The entire work of the Categories, and the whole of Logic I that corresponds to it, deals with simple forms of speech, i.e., with terms, which is the object of the first operation of the intellect. Aristotle's work On Interpretation, which corresponds to Logic II, deals with propositions. Cf. Preliminary lesson.]
