"I am then of opinion," said Crassus, "that nature and genius in the first place contribute most aid to speaking; and that to those writers on the art to whom Antonius just now alluded, it was not skill and method in speaking, but natural talent that was wanting; for there ought to be certain lively powers in the mind and understanding, which may be acute to invent, fertile to explain and adorn, and strong and retentive to remember; and if any one imagines that these powers may be acquired by art (which is false, for it is very well if they can be animated and excited by art; but they certainly cannot by art be ingrafted or instilled, since they are all the gifts of nature), what will he say of those qualities which are certainly born with the man himself--volubility of tongue, tone of voice, strength of lungs, and a peculiar conformation and aspect of the whole countenance and body? I do not say that art cannot improve in these particulars (for I am not ignorant that what is good may be made better by education, and what is not very good may be in some degree polished and amended); but there are some persons so hesitating in their speech, so inharmonious in their tone of voice, or so unwieldy and rude in the air and movements of their bodies, that whatever power they possess either from genius or art, they can never be reckoned in the number of accomplished speakers; while there are others so happily qualified in these respects, so eminently adorned with the gifts of nature, that they seem not to have been born like other men, but molded by some divinity. It is indeed a great task and enterprise for a person to undertake and profess that while every one else is silent, he alone must be heard on the most important subjects, and in a large assembly of men; for there is scarcely any one present who is not sharper and quicker to discover defects in the speaker than merits; and thus whatever offends the hearer effaces the recollection of what is worthy of praise. I do not make these observations for the purpose of altogether deterring young men from the study of oratory, even if they be deficient in some natural endowments. For who does not perceive that to C. Caelius, my contemporary, a new man, the mere mediocrity in speaking which he was enabled to attain was a great honor? Who does not know that Q. Varius, your equal in age, a clumsy uncouth man, has obtained his great popularity by the cultivation of such faculties as he has?
