"Ichneumonidæ" sometimes altered to "parasitic wasps" in paraphrases of this passage.
Paraphrased as "I feel most deeply that this whole question of Creation is too profound for human intellect. A dog might as well speculate on the mind of Newton! Let each man hope and believe what he can." Elbert Hubbard, Little Journeys to the Homes of Great Scientists (1916) page 197 http://books.google.com/books?id=nYArAQAAMAAJ&pg=PA198&f=false. <!-- Sometimes claimed that this appeared in Illustrated London News (21 April 1862), but a full search of every issue of Illustrated London News (1842–2003) through Gale Digital News Vault shows that this passage never appeared. -->
The Life and Letters of Charles Darwin (1887)
Context: With respect to the theological view of the question. This is always painful to me. I am bewildered. I had no intention to write atheistically. But I own that I cannot see as plainly as others do, and as I should wish to do, evidence of design and beneficence on all sides of us. There seems to me too much misery in the world. I cannot persuade myself that a beneficent and omnipotent God would have designedly created the Ichneumonidæ with the express intention of their feeding within the living bodies of Caterpillars, or that a cat should play with mice. Not believing this, I see no necessity in the belief that the eye was expressly designed. On the other hand, I cannot anyhow be contented to view this wonderful universe, and especially the nature of man, and to conclude that everything is the result of brute force. I am inclined to look at everything as resulting from designed laws, with the details, whether good or bad, left to the working out of what we may call chance. Not that this notion at all satisfies me. I feel most deeply that the whole subject is too profound for the human intellect. A dog might as well speculate on the mind of Newton. Let each man hope and believe what he can. Certainly I agree with you that my views are not at all necessarily atheistical.

“Let the mind of man be blind to coming doom; he fears, but leave him hope.”
Sit caeca futuri
mens hominum fati; liceat sperare timenti.

Pharsalia
A Choice of Gods (1972)
Context: I have become a student of the sky and know all the clouds there are and have firmly fixed in mind the various hues of blue that the sky can show — the washed-out, almost invisible blue of a hot, summer noon; the soft robin's egg, sometimes almost greenish blue of a late springtime evening, the darker, almost violet blue of fall. I have become a connoisseur of the coloring that the leaves take on in autumn and I know all the voices and the moods of the woods and river valley. I have, in a measure, entered into communion with nature, and in this wise have followed in the footsteps of Red Cloud and his people, although I am sure that their understanding and their emotions are more fine-tuned than mine are. I have seen, however, the roll of seasons, the birth and death of leaves, the glitter of the stars on more nights than I can number and from all this as from nothing else I have gained a sense of a purpose and an orderliness which it does not seem to me can have stemmed from accident alone.
It seems to me, thinking of it, that there must be some universal plan which set in motion the orbiting of the electrons about the nucleus and the slower, more majestic orbit of the galaxies about one another to the very edge of space. There is a plan, it seems to me, that reaches out of the electron to the rim of the universe and what this plan may be or how it came about is beyond my feeble intellect. But if we are looking for something on which to pin our faith — and, indeed, our hope — the plan might well be it. I think we have thought too small and have been too afraid...
