We are forced to distinguish between three kinds of speech: (1) The external, “rhetorical speech,” in the common meaning of this expression, which only refers to images because they affect the passions. Since these images do not stem from insight, however, they remain an object of opinion. This is the case of the purely emotive, false speech: “rhetoric” in the usual negative sense. (2) The speech which arises exclusively from a rational proceeding. It is true that this is of a demonstrative character, but it cannot have a rhetorical effect because purely rational arguments do not attain to the passions, i.e., “theoretical” speech in the usual sense. (3) The true rhetorical speech. This springs from the archai, nondeductible, moving, and indicative, due to its original images. The original speech is that of the wise man, of the sophos, who is not only epistetai, but who with insight leads, guides, and attracts.

The defects of rationalistic, critical philosophy are much more important than they appear at first sight. By failing to take into account political faculties and the art of eloquence, this philosophy disregards two of the most important branches of human activity. … Vico formulates this idea clearly in De studiorum ratione: “But this order of studies brings with it the disadvantage for young people, that in the future they will neither show intelligence in civil life, not be able to enliven a speech with characteristic colors and warm it with the fire of emotions.”

In Quintilian’s expositions there appears a note of melancholy when he discovers that toward the decline of life, the ratio sneaks in gradually, choking up insight into the original.
