The problem of rhetoric — as the speech that acts on the emotions — can be treated from two points of view. It can be considered simply as a doctrine of a type of speech that the traditional rhetors, politicians, and preachers need, i.e., only as an art, as a technique of persuading. In this case the problems of rhetoric will be limited to questions of practical directions for persuading people and will not have a theoretical character.
From another point of view, however, the problems of rhetoric can be seen as involving a relation to philosophy, to theoretical speech. We can formulate this in the following way: If philosophy aims at being a theoretical mode of thought and speech, can it have a rhetorical character and be expressed in rhetorical forms? The answer seems obvious. Theoretical thinking, as a rational process, excludes every rhetorical element because pathetic influences — the influences of feeling — disturb the clarity of rational thought.
