It is your mind that they want you to surrender—all those who preach the
creed of sacrifice, whatever their tags or their motives, whether they demand
it for the sake of your soul or of your body, whether they promise you another
life in heaven or a full stomach on this earth. Those who start by saying: “It
is selfish to pursue your own wishes, you must sacrifice them to the wishes of
others”—end up by saying: “It is selfish to uphold your convictions, you must
sacrifice them to the convictions of others.”
