Building a better mousetrap merely results in smarter mice.
How so many absurd rules of conduct, as well as so many absurd religious beliefs, have originated, we do not know; nor how it is that they have become, in all quarters of the world, so deeply impressed on the minds of men; but it is worthy of remark that a belief constantly inculcated during the early years of life, while the brain is impressionable, appears to acquire almost the nature of an instinct; and the very essence of an instinct is that it is followed independently of reason.
The more one thinks, the more one feels the hopeless immensity of man’s ignorance.
The world will not be inherited by the strongest, it will be inherited by those most able to change.
By considering the embryological structure of man – the homologies which he presents with the lower animals – the rudiments which he retains – and the reversions to which he is liable, we can partly recall in imagination the former condition of our early progenitors; and we can approximately place them in their proper position in the zoological series. We thus learnt that man is descended from a hairy quadruped, furnished with a tail and pointed ears, probably arboreal in its habit, and an inhabitant of the Old World. This creature, if its whole structure had been examined by a naturalist, would have been classed among the Quadrumana, as surely as would be the common and still more ancient progenitor of the Old and New World monkeys.
It is not the biggest, the brightest or the best that will survive, but those who adapt the quickest.
With savages, the weak in body or mind are soon eliminated. We civilized men, on the other hand, do our utmost to check the process of elimination. We build asylums for the imbecile, the maimed and the sick. Thus the weak members of civilized societies propagate their kind. No one who has attended to the breeding of domestic animals will doubt that this must be highly injurious to the race of man. Hardly anyone is so ignorant as to allow his worst animals to breed.
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.
