Language is an art, like brewing or baking.... It certainly is not a true instinct, for every language has to be learnt.

Man is developed from an ovule, about 125th of an inch in diameter, which differs in no respect from the ovules of other animals.

Light may be shed on man and his origins.

In my most extreme fluctuations I have never been an atheist in the sense of denying the existence of a God ... I think that generally (& more and more so as I grow older) but not always, that an agnostic would be the most correct description of my state of mind.

It is always advisable to perceive clearly our ignorance.

If I had my life to live over again, I would have made a rule to read some poetry and listen to some music at least once every week.

At some future period, not very distant as measured by centuries, the civilised races of man will almost certainly exterminate and replace throughout the world the savage races. At the same time the anthropomorphous apes, as Professor Schaaffhausen has remarked, will no doubt be exterminated. The break will then be rendered wider, for it will intervene between man in a more civilised state as we may hope, than the Caucasian and some ape as low as a baboon, instead of as at present between the negro or Australian and the gorilla.
