The human soul enjoys these rare, classical 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 sleepwalker, and heaven knows what besides, all in our own image, indistinguishable from ourselves to the outside 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 sides treet, pause, breathe freely and take our bearings, or to push ahead, outdistance 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.
