I mention the fact here because it shows how great events are decided by trifles. Scholars, of course, won't have it so. Policies, they say, and the subtly laid schemes of statesmen, are what influence the destinies of nations; the opinions of intellectuals, the writings of philosophers, settle the fate of mankind. Well, they may do their share, but in my experience the course of history is as often settled by someone's having a belly-ache, or not sleeping well, or a sailor getting drunk, or some aristocratic harlot waggling her backside.
