Herodotus said this quote

He asked, 'Croesus, who told you to attack my land and meet me as an enemy instead of a friend?'The King replied, 'It was caused by your good fate and my bad fate. It was the fault of the Greek gods, who with their arrogance, encouraged me to march onto your lands. Nobody is mad enough to choose war whilst there is peace. During times of peace, the sons bury their fathers, but in war it is the fathers who send their sons to the grave.

~ Herodotus

When the rich give a party and the meal is finished, a man carries round amongst the guests a wooden image of a corpse in a coffin, carved and painted to look as much like the real thing as possible, and anything from 18 inches to 3 foot long; he shows it to each guest in turn, and says: Look upon this body as you drink and enjoy yourself; for you will be just like it when you are dead.[Herodotus ‘Histories’, II 82]

~ Herodotus

In peace, children inter their parents; war violates the order of nature and causes parents to inter their children.

~ Herodotus

If an important decision is to be made, they [the Persians] discuss the question when they are drunk, and the following day the master of the house where the discussion was held submits their decision for reconsideration when they are sober. If they still approve it, it is adopted; if not, it is abandoned. Conversely, any decision they make when they are sober, is reconsidered afterwards when they are drunk.

~ Herodotus
