"Of course you want to drive that out of yourself because you want to be wise, not foolish. You also have to allow for the self-serving bias of everybody else because most people are not going to remove it all that successfully, the human condition being what it is. If you don't allow for self-serving bias in your conduct, again you're a fool."

Those who would administer [charity] wisely must, indeed, be wise, for one of the serious obstacles to the improvement of our race is indiscriminate charity. It were better for mankind that the millions of the rich were thrown into the sea than spent to encourage the slothful, the drunken, the unworthy. Of every thousand dollars spent in so-called charity today, it is probable that nine hundred and fifty dollars is unwisely spent - so spent, indeed, as to produce the very evils which it hopes to mitigate or cure.
