Who hath a prospect of the different state of perfect happiness or misery that attends all men after this life, depending on their behavior, the measures of good and evil that govern his choice are mightily changed.
John LockeAll men are liable to error; and most men are, in many points, by passion or interest, under temptation to it.
John LockeIf, then, there must be something eternal, let us see what sort of Being it must be. And to that it is very obvious to Reason, that it must necessarily be a cogitative Being. For it is as impossible to conceive that ever bare incogitative Matter should produce a thinking intelligent Being, as that nothing should of itself produce Matter.
John LockeIt is hard to know what other way men can come to truth, to lay hold of it, if they do not dig and search for it as for gold and hid treasure; but he that does so, must have much earth and rubbish, before he gets the pure metal; sand, and pebbles, and dross usually lie blended with it, but the gold is nevertheless gold, and will enrich the man that employs his pains to seek and separate it.
