The Divine Institutes

Whoever, then, has gained for his country these goods— as they themselves call them— that is, who by the overthrow of cities and the destruction of nations has filled the treasury with money, has taken lands and enriched his country-men— he is extolled with praises to the heaven: in him there is said to be the greatest and perfect virtue. And this is the error not only of the people and the ignorant, but also of philosophers, who even give precepts for injustice, lest folly and wickedness should be wanting in discipline and authority.

Therefore, when they are speaking of the duties relating to warfare, all that discourse is accommodated neither to justice nor to true virtue, but to this life and to civil institutions; and that this is not justice the matter itself declares, and Cicero has testified. “But we,” he says, “are not in possession of the real and life-like figure of true law and genuine justice, we have nothing but delineations and sketches; and I wish that we followed even these, for they are taken from the excellent copies made by nature and truth.”

It is then a delineation and a sketch which they thought to be justice. But what of wisdom? Does not the same man confess that it has no existence in philosophers? “Nor,” he says, “when Fabricius or Aristides is called just, is an example of justice sought from these as from a wise man; for none of these is wise in the sense in which we wish the truly wise to be understood. Nor were they who are esteemed and called wise, Marcus Cato and Caius Lælius, actually wise, nor those well-known seven; but from their constant practice of the 'middle duties,' they bore a certain likeness and appearance of wise men.”

If therefore wisdom is taken away from the philosophers by their own confession, and justice is taken away from those who are regarded as just, it follows that all those descriptions of virtue must be false, because no one can know what true virtue is but he who is just and wise. But no one is just and wise but he whom God has instructed with heavenly precepts.
