“When I tell you that war is the foundation of all the arts, I mean also that it is the foundation of all the high virtues and faculties of men. It is very strange for me to discover this, and very dreadful, but I saw it to be quite an undeniable fact… I found, in brief, that all great nations learned their truth of word and strength of thought in war; that they were nourished in war and wasted in peace; taught by war and deceived by peace; trained by war and betrayed by peace; in a word, that they were born in war and expired in peace.”
John Ruskin, Crown of Wild Olive
Yeah, it’s not really science. But interesting.
