"Ere man could know what was right, he had to learn the existence of the law, and this he could only learn by following all that attracted him in the outer world, by grasping every desirable object, and then by learning from experience, sweet or bitter, whether his delight was in harmony or in conflict with the law. Let us take an obvious example, the taking of pleasant food, and see how infant man might learn there from the presence of a natural law. At the first taking, his hunger was appeased, his taste was gratified, and only pleasure resulted from the experience, for his action was in harmony with law. On another occasion, desiring to increase pleasure, he ate overmuch and suffered in consequence, for he transgressed against the law. A confusing experience to the dawning intelligence, how the pleasurable became painful by excess."
