Do what you can to do what you ought, and leave hoping and fearing alone. - Thomas Henry Huxley

"The propounders of what are called the "ethics of evolution," when the 'evolution of ethics' would usually better express the object of their speculations, adduce a number of more or less interesting facts and more or less sound arguments, in favour of the origin of the moral sentiments, in the same way as other natural phenomena, by a process of evolution. I have little doubt, for my own part, that they are on the right track; but as the immoral sentiments have no less been evolved, there is, so far, as much natural sanction for the one as the other. The thief and the murderer follow nature just as much as the philanthropist. Cosmic evolution may teach us how the good and the evil tendencies of man may have come about; but, in itself, it is incompetent to furnish any better reason why what we call good is preferable to what we call evil than we had before."

Is Man so different from any of these Apes that he must form an order by himself? Or does he differ less from them than they differ from one another, and hence must take his place in the same order with them?

The result is that we have been able to commit, in cold blood and over long periods of time, acts of which the brutes are capable only for brief moments and at the frantic height of Rage, desire, or fear. Because they use and worship symbols, men can become idealists; and, being idealists, they can transform the animal's intermittent greed into the grandiose imperialism of a Rhodes or a JPMorgan; the animal's intermittent love of bullying into Stalinism or the Spanish Inquisition; the animal's intermittent attachment to its territory into the calculated frenzies of nationalism.
