“Christianity… makes frankly impossible demands. Instead of asking for specific actions, it offers general but lunatic principles. It thinks you should give your possessions away, refuse to defend yourself, love strangers as much as your family, behave as if there’s no tomorrow.
These principles do not amount to a sustainable program. They deliberately ignore the question of how they could possibly be maintained. They ask you to manifest in your ordinary life a drastically uncalculating, unprotected generosity.
And that’s not all. Christianity also makes what you mean by your behavior all-important. You could pauperize yourself, get slapped silly without fighting back, care for lepers and laugh all day long in the face of futures markets, and it still wouldn’t count, if you did it for the wrong reasons. Not only is Christianity insanely perfectionist in its few positive recommendations, it’s also insanely perfectionist about motive. It won’t accept generosity performed for the sake of self-interest as generosity. It says that unless altruism is altruism all the way down, it doesn’t count as altruism at all.”
