According to Hermeneutics ch. 4, the analysis of non-assertive
sentences such as wishes, commands, etc. belongs to rhetoric or poetics. They
are, however, examined neither in the Rhetoric, nor in the Poetics,
where in ch. 20 their treatment is explicitly excluded from the art of poetry
and referred to that of delivery or performance. In this paper an explanation
is given for this discrepancy, based on an interpretation of Aristotle's
rejection of Protagoras' criticism of Homer.
