The animal tends to eat with his stomach, and the man with his brain. When the animal's stomach is full, he stops eating, but the man is never sure when to stop. When he has eaten as much as his belly can take, he still feels empty, he still feels an urge for further gratification.
Alan WattsFor we have never actually understood the revolutionary sense beneath them – the incredible truth that what religion calls the vision of God is found in giving up any belief in the idea of God.
