Letters 87.34

The antecedent cause inheres in virtue also; it is this which brings on envy—for many men become unpopular because of their wisdom, and many men because of their justice. But this cause, though it inheres in virtue, is not the result of virtue itself, nor is it a mere semblance of the reality; nay, on the contrary, far more like the reality is that vision which is flashed by virtue upon the spirits of men, summoning them to love it and marvel thereat.
