But it is childish to talk of happiness and unhappiness where infinity is in question. The idea which we entertain of happiness and unhappiness is something so special, so human, so fragile that it does not exceed our stature and falls to dust as soon as we take it out of its little sphere. It proceeds entirely from a few contingencies of our nerves, which are made to appreciate very slight happenings, but which could as easily have felt everything the opposite way and taken pleasure in that which is now pain.
I do not know if my readers remember the striking passage in which Sir William Crookes shows how well-nigh all that we consider as essential laws of nature would be falsified in the eyes of a microscopic man, while forces of which we are almost wholly ignorant, such as surface-tension, capillarity or the Brownian movements, would preponderate. Walking on a cabbage-leaf, for instance, after the dew had fallen, and seeing it studded with huge crystal globes, he would infer that water was a solid body which assumes spherical form and rises in the air. At no great distance, he might come to a pond, when he would observe that this same matter, instead of rising upwards, now seems to slope downwards in a vast curve from the brink. If he managed, with the aid of his friends, to throw into the water one of those enormous steel bars which we call needles, he would see that it made a sort of concave trough on the surface and floated tranquilly. From these experiments and a thousand others which he might make, he would naturally deduce theories diametrically opposed to those upon which our entire existence is based. It would be the same if the changes were made in the direction of time, to take an hypothesis imagined by the philosopher William James:
“Suppose we were able, within the length of a second, to note distinctly ten thousand events instead of barely ten, as now; if our life were then destined to hold the same number of impressions it might be a thousand times as short. We should live less than a month, and personally know nothing of the change of seasons. If born in winter, we should believe in summer as we now believe in the heats of the carboniferous era. The motions of organic beings would be so slow to our senses as to be inferred, not seen. The sun would stand still in the sky, the moon be almost free from change and so on. But now reverse the hypothesis, and suppose a being to get only one thousandth part of the sensations that we get in a given time, and consequently to live a thousand times as long. Winters and summers will be to him like quarters of an hour. Mushrooms and the swifter growing plants will shoot into being so rapidly as to appear instantaneous creations; annual shrubs will rise and fall from the earth like restlessly boiling water-springs; the motions of animals will be as invisible as are to us the movements of bullets and cannon-balls; the sun will scour through the sky like a meteor, leaving a fiery trail behind him, etc. That such imaginary cases (barring the superhuman longevity) may be realized somewhere in the animal kingdom, it would be rash to deny.”

We believe that we see nothing hanging over us but catastrophes, deaths, torments and disasters; we shiver at the mere thought of the great interplanetary spaces, with their intense cold and their awful and gloomy solitudes; and we imagine that the worlds that revolve through space are as unhappy as ourselves because they freeze, or disaggregate, or clash together, or are consumed in unutterable flames. We infer from this that the genius of the universe is an abominable tyrant, seized with a monstrous madness, delighting only in the torture of itself and all that it contains. To millions of stars, each many thousand times larger than our sun, to nebulæ whose nature and dimensions no figure, no word in our language is able to express, we attribute our momentary sensibility, the little ephemeral play of our nerves; and we are convinced that life there must be impossible or appalling, because we should feel too hot or too cold. It were much wiser to say to ourselves that it would need but a trifle, a few papillæ more or less to our skin, the slightest modification of our eyes and ears, to turn the temperature of space, its silence and its darkness into a delicious springtime, an incomparable music, a divine light.
“Nothing is too wonderful to be true,” said Faraday.
It were much more reasonable to persuade ourselves that the catastrophes which our imagination sees there are life itself, the joy and one or other of those immense festivals of mind and matter in which death, thrusting aside at last our two enemies, time and space, will soon permit us to take part. Each world dissolving, extinguished, crumbling, burnt or colliding with another world and pulverized means the commencement of a magnificent experiment, the dawn of a marvellous hope and perhaps an unexpected happiness drawn direct from the inexhaustible unknown. What though they freeze or flame, collect or disperse, pursue or flee one another: mind and matter, no longer united by the same pitiful hazard that joined them in us, must rejoice at all that happens; for all is but birth and rebirth, a departure into an unknown filled with wonderful promises and maybe an anticipation of some ineffable event.
