The Third Notebook: Part Two
No Longer Human

I am ashamed to write the word. Wealth means well-being, weal, the opposite of woe. And is that money? or can money buy it? We boast much of the purity of our faith, of the sins of idolatry among the Romanists, and we send missionaries to the poor unenlightened heathens, to bring them out of their darkness into our light, our glorious light; but oh! if you may measure the fearfulness of an idol by the blood which stains its sacrifice, by the multitude of its victims, where in all the world, in the fetish of the poor negro, in the hideous car of Indian Juggernaut, can you find a monster whose worship is polluted by such enormity as this English one of money!

The Ethics of Belief (1877), The Duty of Inquiry
Context: A bad action is always bad at the time when it is done, no matter what happens afterwards. Every time we let ourselves believe for unworthy reasons, we weaken our powers of self-control, of doubting, of judicially and fairly weighing evidence. We all suffer severely enough from the maintenance and support of false beliefs and the fatally wrong actions which they lead to, and the evil born when one such belief is entertained is great and wide. But a greater and wider evil arises when the credulous character is maintained and supported, when a habit of believing for unworthy reasons is fostered and made permanent. If I steal money from any person, there may be no harm done from the mere transfer of possession; he may not feel the loss, or it may prevent him from using the money badly. But I cannot help doing this great wrong towards Man, that I make myself dishonest. What hurts society is not that it should lose its property, but that it should become a den of thieves, for then it must cease to be society. This is why we ought not to do evil, that good may come; for at any rate this great evil has come, that we have done evil and are made wicked thereby. In like manner, if I let myself believe anything on insufficient evidence, there may be no great harm done by the mere belief; it may be true after all, or I may never have occasion to exhibit it in outward acts. But I cannot help doing this great wrong towards Man, that I make myself credulous. The danger to society is not merely that it should believe wrong things, though that is great enough; but that it should become credulous, and lose the habit of testing things and inquiring into them; for then it must sink back into savagery.
