Charles Kingsley,
Sermons on National Subjects
“ You may as well make house-walls of paper, or take a rush for a walking-stick, as take self-interest to keep you upright, or even prudent. The first shake—and the rush bends, and the paper wall breaks, and a man’s selfish prudence is blown to the winds. Let pleasure tempt him, or ambition, or the lust of making money by speculation; let him take a spite against anyone; let him get into a passion; let his pride be hurt; and he will do the maddest things, which he knows to be entirely contrary to his own interest, just to gratify the fancy of the moment. ”
