That is it--the most we know--alternate eras of evolution and dissolution. In the past there have been other evolutions similar to that one in which we live, and in the future there may be other similar evolutions--that is all. The principle of all these evolutions remains, but the concrete results are never twice alike. Man was not; he was; and again he will not be. In eternity which is beyond our comprehension, the particular evolution of that solar satellite we call the "Earth" occupied but a slight fraction of time. And of that fraction of time man occupies but a small portion. All the whole human drift, from the first ape-man to the last savant, is but a phantom, a flash of light and a flutter of movement across the infinite face of the starry night. When the thermometer drops, man ceases--with all his lusts and wrestlings and achievements; with all his race-adventures and race-tragedies; and with all his red killings, billions upon billions of human lives multiplied by as many billions more. This is the last word of Science, unless there be some further, unguessed word which Science will some day find and utter. In the meantime it sees no farther than the starry void, where the "fleeting systems lapse like foam." Of what ledger-account is the tiny life of man in a vastness where stars snuff out like candles and great suns blaze for a time-tick of eternity and are gone? And for us who live, no worse can happen than has happened to the earliest drifts of man, marked to-day by ruined cities of forgotten civilisation--ruined cities, which, on excavation, are found to rest on ruins of earlier cities, city upon city, and fourteen cities, down to a stratum where, still earlier, wandering herdsmen drove their flocks, and where, even preceding them, wild hunters chased their prey long after the cave-man and the man of the squatting-place cracked the knuckle-bones of wild animals and vanished from the earth. There is nothing terrible about it. With Richard Hovey, when he faced his death, we can say: "Behold! I have lived!" And with another and greater one, we can lay ourselves down with a will. The one drop of living, the one taste of being, has been good; and perhaps our greatest achievement will be that we dreamed immortality, even though we failed to realise it. SMALL-BOAT SAILING
