'I was a young man with uninformed ideas. I threw out queries, suggestions, wondering all the time over everything; and to my astonishment the ideas took like wildfire. People made a religion of them.'
'To suppose that the eye with all its inimitable contrivances for adjusting the focus to different distances, for admitting different amounts of light, and for the correction of spherical and chromatic aberration, could have been formed by natural selections, seems, I confess, absurd in the highest degree.'
'A scientific man ought to have no wishes, no affections, – a mere heart of stone.'
'The mystery of the beginning of all things is insoluble by us; and I for one must be content to remain an agnostic.'
'My theology is a simple muddle: I cannot look at the Universe as the result of blind chance, yet I can see no evidence of beneficent Design.'
'It is a cursed evil to any man to become as absorbed in any subject as I am in mine.'
