Let us select a portion of these laws of the human spirit; such as relate to a man's conduct in dealing with his fellow men, a portion of what are commonly called moral laws, and examine them. They partake of the general characteristics mentioned above; they are universal and unchangeable, are only discovered and not made by man, are inherent in man, designed to secure his welfare, and represent the infinity of God. These laws are absolutely right; to obey them is to be and do absolutely right. So being and doing, a man answers the moral purpose of his existence, and attains moral manhood. If I and all men keep all the laws of man's spirit, I have peace in my own heart, peace with my brother, peace with my God; I have my delight in myself, in my brother, in my God, they theirs and God His in me.
What is absolutely right is commonly called justice. It is the point in morals common to me and all mankind, common to me and God, to mankind and God; the point where all duties unite—to myself, my brethren, and my God; the point where all interests meet and balance—my interests, those of mankind, and the interests of God. When justice is done, all is harmony and peaceful progress in the world of man; but when justice is not done, the reverse follows, discord and confusion; for injustice is not the point where all duties and all interests meet and balance, not the point of morals common to mankind and me, or to us and God.
We may observe and study the constant facts of the material world, thus learn the laws they represent, and so get at a theory of the world which is founded on the facts thereof. Such a theory is true; it represents the thought of God, the infinity of God. Then for every point of theory we have a point of fact. Instead of pursuing this course we may neglect these constant facts, with the laws they represent, and forge a theory which shall not rest on these facts. Such a theory will be false and will represent the imperfection of men, and not the facts of the universe and the infinity of God.
In like manner we may study the constant facts of the spiritual world, and, in special, of man's moral nature, and thereby obtain a rule to regulate our conduct. If this rule is founded on the constant facts of man's moral nature, then it will be absolutely right, and represent Justice, the thought of God, the infinity of God, and for every point of moral theory we shall have a moral fact. Instead of pursuing that course, we may forge a rule for our conduct, and so get a theory which shall not rest on those facts. Such a rule will be wrong, representing only the imperfection of men.
In striving to learn the laws of the universe, the wisest men often go astray, propound theories which do not rest upon facts, and lay down human rules for the conduct of the universe, which do not agree with its nature. But the universe is not responsible for that; material nature takes no notice thereof. The opinion of an astronomer, of the American academy, does not alter a law of the material universe, or a fact therein. The philosophers once thought that the sun went round the earth, and framed laws on that assumption; but that did not make it a fact; the sun did not go out of his way to verify the theory, but kept to the law of God, and swung the earth round him once a year, say the philosophers what they might say, leaving them to learn the fact and thereby correct their theory.
In the same way, before men attain a knowledge of the absolute right, they often make theories which do not rest upon the facts of man's moral nature, and enact human rules for the conduct of men which do not agree with the moral nature of man. These are rules which men make and do not find made. They are not a part of man's moral nature, writ therein, and so obligatory thereon, no more than the false rules for the conduct of matter are writ therein, and so obligatory thereon. You and I are no more morally bound to keep such rules of conduct, because King Pharaoh or King People say we shall, than the sun is materially bound to go round the earth every day, because Hipparchus and Ptolemy say it does. The opinion or command of a king, or a people, can no more change a fact and alter a law of man's nature, than the opinion of a philosopher can do this in material nature.
We learn the laws of matter slowly, by observation, experiment, and induction, and only get an outside knowledge thereof, as objects of thought. In the same way we might study the facts of man's moral nature, and arrive at rules of conduct, and get a merely outside acquaintance with the moral law as something wholly external. The law might appear curious, useful, even beautiful, moral gravitation as wonderful as material attraction. But no sense of duty would attach us to it. In addition to the purely intellectual powers, we have a faculty whose special function it is to discover the rules for a man's moral conduct. This is Conscience, called also by many names. As the mind has for its object absolute truth, so conscience has for its object absolute justice. Conscience enables us not merely to learn the right by experiment and induction, but intuitively, and in advance of experiment; so, in addition to the experimental way, whereby we learn justice from the facts of human history, we have a transcendental way, and learn it from the facts of human nature, from immediate consciousness.
It is the function of conscience to discover to men the moral law of God. It will not do this with infallible certainty, for, at its best estate, neither conscience nor any other faculty of man is absolutely perfect, so as never to mistake. Absolute perfection belongs only to the faculties of God. But conscience, like each other faculty, is relatively perfect,—is adequate to the purpose God meant it for. It is often immature in the young, who have not had time for the growth and ripening of the faculty, and in the old, who have checked and hindered its development. Here it is feeble from neglect, there from abuse. It may give an imperfect answer to the question, What is absolutely right?
Now, though the conscience of a man lacks the absolute perfection of that of God, in all that relates to my dealing with men, it is still the last standard of appeal. I will hear what my friends have to say, what public opinion has to offer, what the best men can advise me to, then I am to ask my own conscience, and follow its decision; not that of my next friend, the public, or the best of men. I will not say that my conscience will always disclose to me the absolutely right, according to the conscience of God, but it will disclose the relatively right, what is my conviction of right to-day, with all the light I can get on the matter; and as all I can know of the absolute right, is my conviction thereof, so I must be true to that conviction. Then I am faithful to my own conscience, and faithful to my God. If I do the best thing I can know to-day, and to-morrow find a better one and do that, I am not to be blamed, nor to be called a sinner against God, because not so just to-day as I shall be to-morrow. I am to do God's will soon as I know it, not before, and to take all possible pains to find it out; but am not to blame for acting childish when a child, nor to be ashamed of it when grown up to be a man. Such is the function of conscience.
