Rudolf Steiner: "Let us ascend to what acts in the astral body as the sentient soul. Therein we have an I working in a muted way which has not yet properly emerged and which therefore still develops the worst kind of passionate egoism. For as long as the I is still thoroughly stuck in the sentient soul, it develops the most selfish egoism. It is then devoid of any wish to allow others what it has itself. Egoism dulls the sense of justice because the I wants to have everything for itself."
