I am turned into a sort of machine for observing facts and grinding out conclusions.
A scientific man ought to have no wishes, no affections, – a mere heart of stone.
Animals, whom we have made our slaves, we do not like to consider our equal.
We can allow satellites, planets, suns, universe, nay whole systems of universes, to be governed by laws, but the smallest insect, we wish to be created at once by special act.
I cannot persuade myself that a beneficent and omnipotent God would have designedly created parasitic wasps with the express intention of their feeding within the living bodies of Caterpillars.
I am not apt to follow blindly the lead of other men
It may be said that natural selection is daily and hourly scrutinising, throughout the world, every variation, even the slightest; rejecting that which is bad, preserving and adding up all that is good; silently and insensibly working, whenever and wherever opportunity offers, at the improvement of each organic being in relation to its organic and in organic conditions of life. We see nothing of these slow changes in progress, until the hand of time has marked the long lapse of ages, and then so imperfect is our view into long-past geological ages, that we only see that the forms of life are now different from what they formerly were.
Man is descended from a hairy, tailed quadruped, probably arboreal in its habits.
My mind seems to have become a kind of machine for grinding general laws out of large collections of facts.
It is not the strongest of the species that survives, not the most intelligent that survives. It is the one that is the most adaptable to change.
