As we passed under a streetlamp I noticed, beside my own bobbing shadow, another great, leaping grotesquerie that had an uncanny suggestion of the frog world about it . . . judging from the shadow, it was soaring higher and more gaily than myself. 'Very well,' you will say, 'Why didn’t you turn around. That would be the scientific thing to do.' But let me tell you it is not done ― not on an empty road at midnight.

We are one of many appearances of the thing called Life; we are not its perfect image, for it has no perfect image except Life, and life is multitudinous and emergent in the stream of time.

Animals are molded by natural forces they do not comprehend. To their minds there is no past and no future. There is only the everlasting present of a single generation, its trails in the forest, its hidden pathways in the the air and in the sea. There is nothing in the Universe more alone than Man. He has entered into the strange world of history.

I am older now, and sleep less, and have seen most of what there is to see and am not very much impressed any more, I suppose, by anything.

If there is magic on this planet, it is contained in water.

Great minds have always seen it. That is why man has survived his journey this long. When we fail to wish any longer to be otherwise than what we are, we will have ceased to evolve. Evolution has to be lived forward. I say this as one who has stood above the bones of much that has vanished, and at midnight has examined his own face.

It is surely one of the curious paradoxes of history that science which professionally has little to do with faith, owes its origins to an act of faith that the universe can be rationally interpreted, and that science today is sustained by that assumption.
