Scurrility has no object in view but incivility; if it is uttered from feelings of petulance, it is mere abuse; if it is spoken in a joking manner, it may be considered raillery.
Marcus Tullius CiceroOn the subject of the nature of the gods, the first question is Do the gods exist or do the not? It is difficult you may say to deny that they exist. I would agree if we were arguing the matter in a public assembly, but in a private discussion of this kind, it is perfectly easy to do so.
Marcus Tullius CiceroA nation can survive its fools, and even the ambitious. But it cannot survive treason from within. An enemy at the gates is less formidable, for he is known and carries his banner openly. But the traitor moves amongst those within the gate freely, his sly whispers rustling through all the alleys, heard in the very halls of government itself.
Marcus Tullius CiceroLet us assume that entertainment is the sole end of reading; even so I think you would hold that no mental employment is so broadening to the sympathies or so enlightening to the understanding. Other pursuits belong not to all times, all ages, all conditions; but this gives stimulus to our youth and diversion to our old age; this adds a charm to success, and offers a haven of consolation to failure. Through the night-watches, on all our journeyings, and in our hours of ease, it is our unfailing companion.
