"We are becoming accustomed to a conception of the universe so mysterious and so impressive that even the best father-image will no longer do for an explanation of what makes it run. But the problem then is that it is impossible for us to conceive an image higher than the human image. Few of us have ever met an angel, and probably would not recognize it if we saw one, and our images of an impersonal or suprapersonal God are hopelessly subhuman—jello, featureless light, homogenized space, or a whopping jolt of electricity. However, our image of man is changing as it becomes clearer and clearer that the human being is notsimply and only his physical organism. My body is also my total environment, and this must be measured by light-years in the billions. Hitherto the poets and philosophers of science have used the vast expanse and duration of the universe as a pretext for reflections on the unimportance of man, forgetting that man with "that enchanted loom, the brain" is precisely what transforms this immense electrical pulsation into light and color, shape and sound, large and small, hard and heavy, long and short. In knowing the world we humanize it, and if, as we discover it, we are astonished at its dimensions and its complexity, we should be just as astonished that we have the brains to perceive it."
