Institutio Oratoria

Cicero, on the other hand, was regarded as being unduly addicted to jests, not merely outside the courts, but in his actual speeches as well. Personally (though whether I am right in this view, or have been led astray by an exaggerated admiration for the prince of orators, I cannot say),

while in his disputes in court and in his examination of witnesses he produced more good jests than any other, while the somewhat insipid jokes which he launches against Verres are always attributed by him to others and produced as evidence: wherefore, the more vulgar they are, the more probable is it that they are not the invention of the orator, but were current as public property. I wish, however,

that Tiro, or whoever it may have been that published the three books of Cicero's jests, had restricted their number and had shown more judgment in selecting than zeal in collecting them. For he would then have been less exposed to the censure of his calumniators, although the latter will, in any case, as in regard to all the manifestations of his genius, find it easier to detect superfluities than deficiencies.

The chief difficulty which confronts the orator in this connexion lies in the fact that sayings designed to raise a laugh are generally untrue (and falsehood always involves a certain meanness), and are often deliberately distorted, and, further, never complimentary: while the judgments formed by the audience on such jests will necessarily vary, since the effect of a jest depends not on the reason, but on an emotion which it is difficult, if not impossible, to describe.
