What! they who would speak louder than ordinary are they satisfied with working their jaws, sides, or tongue or stretching the common organs of speech and utterance?
The whole body and every muscle is at full stretch if I may be allowed the expression; every nerve is exerted to assist their voice.

I have actually seen the knees of Marcus Antonius touch the ground when he was speaking with vehemence for himself, with relation to the Varian law.

For, as the engines you throw stones or darts with throw them out with the greater force the more they are strained and drawn back; so it is in speaking, running, or boxing--the more people strain themselves, the greater their force.
Since, therefore, this exertion has so much influence--if in a moment of pain groans help to strengthen the mind, let us use them; but if they be groans of lamentation, if they be the expression of weakness or abjectness, or unmanly weeping, then I should scarcely call him a man who yielded to them.

For even supposing that such groaning could give any ease, it still should be considered whether it were consistent with a brave and resolute man.

But if it does not ease our pain, why should we debase ourselves to no purpose?
For what is more unbecoming in a man than to cry like a woman?
But this precept which is laid down with respect to pain is not confined to it.
