"Given the nature of spiders, webs are inevitable. And given the nature of human beings, so are religions. Spiders can't help making fly-traps, and men can't help making symbols. That's what the human brain is there for - the turn the chaos of given experience into a set of manageable symbols."

The reason why you do history, and particularly why you do war, is that you want to make sure that in the next war, some lessons were learned. There's a saying: "History doesn't repeat itself, but it does rhyme." Or Ecclesiastes: "What has been will be again. What has been done will be done again." Human nature always superimposes itself - its strength and its frailty over the rush of chaos of ongoing events - and we can perceive patterns and themes and motifs.
