(5.) It cannot be measured by the intrinsic value of the good, or well-being of God and the universe, without reference to the knowledge of the agent, for the same reason as above.

(6.) It cannot be measured by the particular course of life pursued by the agent. This will appear, if we consider that moral obligation has directly nothing to do with the outward life. It directly respects the ultimate intention only, and that decides the course of outward action or life. The guilt of any outward action cannot be decided by reference to the kind of action, without regard to the intention; for the moral character of the act must be found in the intention, and not in the outward act or life. This leads me to remark that:

(7.) The degree of moral obligation, and of course the degree of the guilt of disobedience, cannot be properly estimated by reference to the nature of the intention, without respect to the degree of the knowledge of the agent. Selfish intention is, as we have seen, a unit, always the same; and if this were the standard by which the degree of guilt is to be measured, it would follow that it is always the same.

(8.) Nor can obligation, nor the degree of guilt, be measured by the tendency of sin. All sin tends to infinite evil, to ruin the sinner and from its contagious nature, to spread and ruin the universe. Nor can any finite mind know what the ultimate results of any sin may be, nor to what particular evil it may tend. As all sin tends to universal and eternal evil, if this were the criterion by which the guilt is to be estimated, all sin would be equally guilty, which cannot be.

Again: That the guilt of sin cannot be measured by the tendency of sin, is manifest from the fact, that moral obligation is not founded in the tendency of action or intention, but in the intrinsic value of the end to be intended. Estimating moral obligation, or measuring sin or holiness, by the mere tendency of actions, is the utilitarian philosophy, which we have shown to be false. Moral obligation respects the choice of an end, and is founded upon the intrinsic value of the end, and is not so much as conditionated upon the tendency of the ultimate choice to secure its end. Therefore, tendency can never be the rule by which obligation can be measured, nor, of course, the rule by which guilt can be estimated.

(9.) Nor can moral obligation be estimated by the results of a moral action or course of action. Moral obligation respects intention and respects results no further than they were intended. Much good may result, as from the death of Christ, without any virtue in Judas, but with much guilt. So, much evil may result, as from the creation of the world, without guilt in the Creator, but with great virtue. If moral obligation is not founded or conditionated on results, it follows that guilt cannot be duly estimated by results, without reference to knowledge and intention.

(10.) What has been said has, I trust, rendered it evident, that moral obligation is to be measured by the mind's honest apprehension or judgment of the intrinsic value of the end to be chosen, to wit, the highest well-being of God and the universe.

It should be distinctly understood, that selfishness involves the rejection of the interests of God and of the universe, for the sake of one's own. It refuses to will good, but upon condition that it belongs to self. It spurns God's interests and those of the universe, and seeks only self-interest as an ultimate end. It must follow, then, that the selfish man's guilt is just equal to his knowledge of the intrinsic value of those interests that he rejects. This is undeniably the doctrine of the Bible.

Acts affords a plain instance. The apostle alludes to those past ages when the heathen nations had no written revelation from God, and remarks that "those times of ignorance God winked at" (Acts 17:30). This does not mean that God did not regard their conduct as criminal in any degree, but it does mean that He regarded it as a sin of far less aggravation, than that which men would now commit, if they turned away when God commanded them all to repent. True, sin is never absolutely a light thing; but some sins incur small guilt, when compared with the great guilt of other sins. This is implied in the text quoted above. "To him that knoweth to do good, and doeth it not, to him it is sin" (James 4:17). This plainly implies that knowledge is indispensable to moral obligation; and even more than this is implied, namely, that the guilt of any sinner is always equal to the amount of his knowledge on the subject. It always corresponds to the mind's perception of the value of the end which should have been chosen, but is rejected. If a man knows he ought, in any given case, to do good, and yet does not do it, to him this is sin the sin plainly lying in the fact of not doing good when he knew that he could do it, and being measured as to its guilt by the degree of that knowledge.

"Jesus said unto them, If ye were blind, ye should have no sin: but now ye say, We see; therefore, your sin remaineth" (John 9:41). Here Christ asserts that men without knowledge would be without sin; and that men who have knowledge, and sin nevertheless, are held guilty. This plainly affirms, that the presence of light or knowledge is requisite to the existence of sin, and obviously implies that the amount of knowledge possessed is the measure of the guilt of sin.

It is remarkable that the Bible everywhere assumes first truths. It does not stop to prove them, or even assert them but seems to assume, that every one knows and will admit them. As I have been recently writing on moral government, and studying the Bible as to its teachings on this class of subjects, I have been often struck with this remarkable fact.

"And that servant which knew his lord's will, and prepared not himself, neither did according to his will, shall be beaten with many stripes. But he that knew not, and did commit things worthy of stripes, shall be beaten with few stripes. For unto whomsoever much is given, of him shall be much required; and to whom men have committed much, of him will they ask the more" (Luke 12:47, 48). Here we have the doctrine laid down and the truth assumed, that men shall be punished according to knowledge. To whom much light is given, of him shall much obedience be required. This is precisely the principle, that God requires of men according to the light they have.

Selfishness is the rejection of all obligation. It is the violation of all obligation. The sin of selfishness is then complete; that is, the guilt of selfishness is as great as with its present light it can be. What can make it greater with present light? Can the course that it takes to realize its end mitigate its guilt? No; for whatever course it takes, it is for a selfish reason, and, therefore, it can in nowise lessen the guilt of the intention. Can the course it takes to realize its end without more light, increase the guilt of the sin? No; for the sin lies exclusively in having the selfish intention, and the guilt can be measured only by the degree of illumination or knowledge under which the intention is formed and maintained. The intention necessitates the use of the means; and whatever means the selfish person uses, it is for one and the same reason, to gratify himself. As I said in a former lecture, if the selfish man were to preach the gospel, it would be only because, upon the whole, it was most pleasing or gratifying to himself, and not at all for the sake of the good of being, as an end. If he should become a pirate, it would be for exactly the same reason, to wit, that this course is, upon the whole, most pleasing or gratifying to himself, and not at all for the reason that course is evil in itself. Whichever course he takes, he takes it for precisely the same ultimate reason; and with the same degree of light it must involve the same degree of guilt. If light increase, his guilt must increase, but not otherwise. The proposition is, that every selfish being is, at every moment, as blameworthy as with his present knowledge he can be. Which of these courses may tend ultimately to the most evil, no finite being can say, nor which shall result in the greatest evil. Guilt is not to be measured by unknown tendencies or results, but belongs to the intention; and its degree is to be measured alone by the mind's apprehension of the reason of the obligation violated, namely, the intrinsic value of the good of God and the universe, which selfishness rejects. Now, it should be remembered, that whichever course the sinner takes to realize his end, it is the end at which he aims. He intends the end. If he become a preacher of the gospel for a selfish reason, he has no right regard to the good of being. If he regards it at all, it is only as a means of his own good. So, if he becomes a pirate, it is not from malice, or a disposition to do evil for its own sake, but only to gratify himself. If he has any regard at all to the evil he may do, it is only to gratify himself that he regards it. Whether, therefore, he preach or pray, or rob and plunder upon the high seas, he does it only for one end, that is, for precisely the same ultimate reason; and of course his sinfulness is complete, in the sense that it can be varied only by varying light. This I know is contrary to common opinion, but it is the truth, and must be known; and it is of the highest importance that these fundamental truths of morality and of immorality should be held up to the minds of all.

Should the sinner abstain from any course of vice because it is wicked, it cannot be because he is benevolent, for this would contradict the supposition that he is selfish, or that he is a sinner. If, in consideration that an act or course is wicked, he abstains from it, it must be for a selfish reason. It may be in obedience to phrenological conscientiousness, or it may be from fear of hell, or of disgrace, or from remorse; at all events, it cannot but be for some selfish reason.
