It seems to me that an unjust law is no law at all.

Punishment is justice for the unjust.

Did I wish even by stealth to do contrary to Thy law, because by power I could not, so that being a prisoner, I might mimic a maimed liberty by doing with impunity things unpermitted me, a darkened likeness of Thy Omnipotency?

Oh Lord, give me chastity, but do not give it yet.

What then is time? If no one asks me, I know what it is. If I wish to explain it to him who asks, I do not know.

If I am given a formula, and I am ignorant of its meaning, it cannot teach me anything, but if I already know it what does the formula teach me?
