Samuel Butler, Canterbury Pieces
“ Once grant the principles, once grant that competition is a great power in Nature, and that changes of circumstances and habits produce a tendency to variation in the offspring (no matter how slight such variation may be) , and unless you can define the possible limit of such variation during an infinite series of generations, unless you can show that there is a limit, and that Darwin’s theory over-steps it, you have no right to reject his conclusions. As for the objections to the theory, Darwin has treated them with admirable candour, and our time is too brief to enter into them here. ”
