Quibbling against this is self-contradictory. There must inescapably be real difficulties with that. Necessarily when a man takes to altruism, he must in reality agree to his loss of pursuing his own preferences, that is, he will be losing his freedom. That is a high price to pay for altruism. The situation worsens in proportion as the nine are disagreed.
Altruism is inescapably a meddling in the lives of other people.
Difficulty with the non-freedom aspect of altruism can be made more obvious. Imagine the ten people to be a family, consisting of a father, mother, and several children, bound together by affection and responsibility. The Hebrew and Christian religions have never faltered in their answer. It is that the son, having come to maturity, is to make the decision. If it can be pretended to be morality, it can never be pretended to be sense.
