My theme is memory, that winged host that soared about me one gray morning of wartime. These memories, which are my life--for we possess nothing certainly except the past--were always with me. Like the pigeons of St. Mark's, they were everywhere, under my feet, singly, in pairs, in little honey-voiced congregations, nodding, strutting, winking, rolling the tender feathers of their necks, perching sometimes, if I stood still, on my shoulder or pecking a broken biscuit from between my lips; until, suddenly, the noon gun boomed and in a moment, with a flutter and sweep of wings, the pavement was bare and the whole sky above dark with a tumult of fowl. Thus, it was that morning. These memories are the memorials and pledges of the vital hours of a lifetime. These hours of afflatus in the human spirit, the springs of art, are, in their mystery, akin to the epochs of history, when a race which for centuries has lived content, unknown, behind its own frontiers, digging, eating, sleeping, begetting, doing what was requisite for survival and nothing else, will, for a generation or two, stupefy the world; commit all manner of crimes, perhaps; follow the wildest chimeras, go down in the end in agony, but leave behind a record of new heights scaled, and new rewards won for all mankind; the vision fades, the soul sickens, and the routine of survival starts again. The human soul enjoys these rare, classic periods, but, apart from them, we are seldom single or unique; we keep company in this world with a hoard of abstractions and reflections and counterfeits of ourselves -- the sensual man, the economic man, the man of reason, the beast, the machine and the sleep-walker, and heaven knows what besides, all in our own image, indistinguishable from ourselves to the outward eye. We get borne along, out of sight in the press, unresisting, till we get the chance to drop behind unnoticed, or to dodge down a side street, pause, breathe freely and take our bearings, or to push ahead, out-distance our shadows, lead them a dance, so that when at length they catch up with us, they look at one another askance, knowing we have a secret we shall never share.
