Nature (n.) made man for society — what Nature is, and whether she really exists, are questions we need not bother ourselves with.
Nature (n.) shows its will in what we agree on about others: another's broken cup is "one of the things that happen"; another's dead child is "the fate of man" — until it is our own.
Nature (n.) cannot be proved by majority: by that reasoning tumours are good for the body and error is natural, since most of us err.
Nature (n.) is the strongest thing in men: it roused Epicurus from sleep, as the Furies roused Orestes, to herald his own anti-social doctrines.
Nature (n.) has one function above the rest: to make our choice to act agree with a correct sense of the appropriate and beneficial.
Nature (n.) is not what most people do: by that logic tumours would be good for the body, and error natural because nearly all of us err.
