Things sacred should not only be touched with the hands, but unviolated in thought.
[Lat., Res sacros non modo manibus attingi, sed ne cogitatione quidem violari fas fuit.]
Virtue is uniform, conformable to reason, and of unvarying consistency; nothing can be added to it that can make it more than virtue; nothing can be taken from it, and the name of virtue be left.
What is morally wrong can never be advantageous, even when it enables you to make some gain that you believe to be to your advantage. The mere act of believing that some wrongful course of action constitutes an advantage is pernicious.
Do not blame Caesar, blame the people of Rome who have so enthusiastically acclaimed and adored him and rejoiced in their loss of freedom and danced in his path and gave him triumphal processions. Blame the people who hail him when he speaks in the Forum of the 'new, wonderful good society' which shall now be Rome, interpreted to mean 'more money, more ease, more security, more living fatly at the expense of the industrious.'
Socrates, indeed, when he was asked of what country he called himself, said, "Of the world"; for he considered himself an inhabitant and a citizen of the whole world.
