Eloquence (from Latin eloquentia) is fluent, forcible, elegant or persuasive speaking in public. It is primarily the power of expressing strong emotions in striking and appropriate language, thereby producing conviction or persuasion. The term is also used for writing in a fluent style.

Some people say that eloquence is a talent and a gift of nature. Others are of the opinion that it could be acquired by exercise and study. Most people would agree that it is impossible for eloquent persons to affect their hearers in any degree without being affected by themselves.

"True eloquence," Oliver Goldsmith says, does not consist ... in saying great things in a sublime style, but in a simple style; for there is, properly speaking, no such thing as a sublime style, the sublimity lies only in the things; and when they are not so, the language may be turgid, affected, metaphorical, but not affecting." (Of Eloquence, 1759)

In contrast with empathy, eloquence is often thought of as vacuous, brazen and hollow. "Though I speak with the tongues of men and of angels, and have not charity, I am become as sounding brass, or a tinkling cymbal." (I Cor 13:1).

Pericles was perhaps the most perfect public speaker who ever lived, for he was the man who most perfectly combined thought and wisdom with feeling and eloquence. Yet Plato brings in Alcibiades declaring, that men went away from the eloquence of Pericles, saying it was very fine, it was very good, and afterwards thinking no more about it; but they went away from hearing Socrates talk, he says, with the point of what he had said sticking fast in their minds, and they could not get rid of it. Socrates is poisoned and dead; but in his own breast does not every man carry about with him a possible Socrates, in that power of a disinterested play of consciousness upon his stock notions and habits, of which this wise and admirable man gave all through his lifetime the great example, and which was the secret of his incomparable influence? And he who leads men to call forth and exercise in themselves this power, and who busily calls it forth and exercises it in himself, is at the present moment, perhaps, as Socrates was in his time, more in concert with the vital working of men's minds, and more effectually significant, than any orator, or politician.
