Chapter 2 begins with an outline of the four passages in which Aristotle introduces the three pillars of lexis and then moves on to two sections in which the first, i.e. ἅπασα λέξις (the entirety of lexis), is discussed. This first level of lexis includes the linguistic elements treated under the notion of lexis and Aristotle’s theory of language. These not only present Aristotle’s thoughts on language as an abstract system, but they also form the most fundamental level upon which the remainder of Aristotle’s thoughts on the concept of lexis are based.
