Pax Hominibus Bonae Voluntatis by Aleister Crowley in International, Dec 1917.
“It is necessary in many circumstances to fight; and, in order to fight well, one needs certain quite definite qualities. In olden days I did a good deal of fencing, by which I do not mean receiving stolen goods. I mean the play of rapier and small-sword. I learned that I must be entirely concentrated on the business on hand, and that elaborate arguments purporting to prove that my opponent was a Chinaman or a heretic, were out of place.” [via]
