From the relation between the Creator and the creatures arises the natural law. Violation of this law is the source of all moral evil in the world, and of much of the physical evil. Reason shows us this law, and the method of observing it; and reason and unreason, observance or disregard, of the order fixed by the natural law are the foundation of happiness and unhappiness. Whatever a human being is or does, he must seek happiness; that is an essential quality of his being. Happiness is the satisfying of our desires; but as our desires are limitless, only infinite good can satisfy them. The sole sufficient good that sates all human longing is the infinite Necessary Being, and to be happy we must be united with that Being. Obviously the only possible method of possessing this infinite God is through mental union, by undisturbable contemplation of his infinite truth, goodness, being, beauty, and his other attributes. If perfect, everlasting happiness is not in that, in what can it be? Is it in human fame, honor, riches, science, art, man, woman, or child? None of these can give _lasting_ happiness, and no other happiness is real happiness. Now, the only means we have to obtain union with infinite good is to follow out the condition inexorably placed by God, which is to act in life in keeping with right reason, to obey the law. Man's supreme honor is in freedom from the tyranny of unreason, and in a full obedience to external and immovable order, with the belief that his chief duty is to apprehend and to conform thereto. This is morality. From the beginning men have held that certain acts are wrong and to be avoided, and that others are to be done. What is wrong, moreover, is such of its own nature, not from our will: we deem the fulfillment of duty, obedience to law, the first, highest, and last necessity of life. If we deny this truth we let in chaos. What is right or wrong is one or the other on its own merits, prescinding from its pleasurableness or pain. We must seek good whether we will or not. Good is the sole object upon which the will operates, it is the raw material of the will's business. The ultimate standard of this good is God himself as its exemplary cause, but proximately the standard of moral good is our rational nature. Through our reason we judge whether a thing is good or bad; that is, whether it perfects or injures us; and as it is good or bad for us our will's tendency toward it is good or bad. Many acts are indifferent in themselves, but take on a good or bad quality from our intention; others are good or bad in themselves apart from our volition: charity is good, lying is bad, whether they are willed by us or not. The morality of any action is determined (1) by the object of the action; (2) by the circumstances that accompany the action; (3) by the end the agent had in view.
