A little poison now and then: that makes for pleasant dreams. And a lot of poison at the end, for a pleasant death.
Friedrich NietzscheAgainst war one might say that it makes the victor stupid and the vanquished malicious. In its favor, that in producing these two effects it barbarizes, and so makes the combatants more natural. For culture it is a sleep or a wintertime, and man emerges from it stronger for good and for evil.
Friedrich Nietzsche
