History of the Peloponnesian War

For we have this characteristic also in a remarkable degree, that we are at the same time most daring and most calculating in what we take in an hand; whereas to other men it is ignorance that brings daring, while calculation brings fear. Those, however, would deservedly be deemed most courageous, who know most fully what is terrible and what is pleasant, and yet do not on this account shrink from dangers. As regards beneficence also we differ from the generality of men;

for we make friends, not by receiving, but by conferring kindness. Now he who has conferred the favour is the firmer friend, in order that he may keep alive the obligation by good will towards the man on whom he has conferred it; whereas he who owes it in return feels less keenly, knowing that it is not as a favour, but as a debt, that he will repay the kindness.

Nay, we are the only men who fearlessly benefit any one, not so much from calculations of expediency, as with the confidence of liberality.
