Its fundamental proposition is not an axiom but a problem to be solved;

It is expressed in terms possessing no fixed acceptation;

It would require omniscience to carry it into practice;

And, moreover, it takes imperfection for its basis.

The existence of society argues a certain fitness and desire of mankind for it; without this, it would not exist, as eating and drinking, and the nourishment and protection of offspring would not take place if there were no corresponding desires, but merely an abstract opinion in favor of the worth of the two. In the method of nature, there is always some prompter, called a desire, answering to each of the actions which it is requisite for us to perform. It is probable, therefore, that we shall find an instrumentality of this sort prompting us to morality. In objection to the theory of a moral sense, the want of uniformity in judgment as to what is right is often advanced. But none deny the importance of appetite, though all know that it is by no means an infallible guide in the choice of kind or quantity of food. The same may be said of parental affection. The foundation of the claim of any man that he has as great a right to happiness as any other can be found in the last analysis in feeling only; he feels that it is so.

None but those committed to a preconceived theory can fail to recognize the workings of such a faculty as the moral sense. It is clear that the perceptions of propriety or impropriety of conduct do not originate with the intellect but with the emotional faculties. The intellect, uninfluenced by desire, would show both miser and spendthrift that their habits were unwise; whereas the intellect, influenced by desire, makes each think the other a fool, but does not enable him to see his own foolishness.

This is a universal law: Every feeling is accompanied by a sense of the rightness of those actions which give it gratification. From an impulse to behave in a way we call equitable arises a perception that it is proper, and a conviction that it is good. There is, however, a perpetual conflict amongst feelings, from which results an incongruity of beliefs.

It has been said that codes derived from the moral sense have no stability since this sense ratifies one principle at one time and place, another at another. The same objection applies, however, to every other system of morals, and happily there is an answer to the objection. The error criticised is one of application, not of doctrine. The decisions of the Geometric Sense are conflicting; yet there are certain axioms upon which all agree; and in the same manner there are moral axioms to be found, upon which all must agree. Disagreement is to be looked for among imperfect characters. But nature's laws know no exception: Obey or suffer are the alternatives. A progress from entire unconsciousness of these laws to the conviction that law is universal and inevitable, constancy an essential attribute of divine rule, is the substance of the progress of man. The end of these unbending utterances is universal good; we have no alternative but to assume the law of constancy to be the best possible one. As with the physical, so with the ethical; all religions teach the inevitableness of punishment and reward, with which deeds are necessarily and indissolubly connected. It is of infinite importance to recognize and follow the laws of society. To the objection that one cannot always be guided by abstract principles, that there are exceptions where prudence must act, it may be replied that there are no exceptions to the laws of nature; that even if, in a particular instance, partial good may result, a far greater general evil is entailed by the opening of the way to future disobediences, and that we cannot, moreover, be sure that an exceptional disobedience will bring the anticipated benefits. Moral as well as physical evil is the result of a want of congruity between the faculties and their sphere of action. With regard to the results of varying conditions upon man, we have three alternative theories from which to choose: either man remains entirely unaltered by his surroundings, or he grows more unfitted for them, or else he grows more fitted for them. The first two suppositions being absurd, we are obliged to admit the remaining one. And since all evil results from non-adaptation, and non-adaptation is being continually diminished, it follows that evil must be continually diminishing. The evil in society shows that man is not yet completely adapted to a state which requires that each individual shall have such desires only as may be fully satisfied without trenching upon the ability of other individuals to obtain a like satisfaction. The primitive condition of man required that he should sacrifice the welfare of other beings to his own; the old attribute still clings to him in some measure; the belief in human perfectibility amounts to the belief that man will eventually become completely suited to his mode of life. Progress is not an accident but a necessity; and if, instead of proposing it as a rule of human conduct, Bentham had simply assumed the "greatest happiness" to be the creative purpose, his position would have been tenable enough. It is one thing, however, to hold that greatest happiness is the creative purpose, and quite a different thing to hold that greatest happiness should be the immediate aim of mankind. Truth has two sides, a divine and a human; or, it is for man to ascertain the conditions which lead to the greatest happiness, and to live in conformity with these.

The men who are to realize this greatest sum of happiness must be such as can obtain complete happiness without diminishing the activity and happiness of others. The first great condition of the attainment of the end is, therefore, justice, and, as a supplement to this, negative and positive beneficence,—abstinence from diminishing the spheres of activity of others, and further, a positive increase of their pleasure. For man is sympathetic, and the sympathetic pleasures increase the sum total of happiness.

The exercise[38] of all the faculties in which happiness consists is not only man's right but also his duty. For the fact of pain, of punishment, proves that God intends and wills such exercise. But the exercise of all the faculties is freedom; all men have, therefore, a right to freedom of action. This principle, however, implies a limitation of man by men, whereby we arrive at the general proposition that every man may claim the fullest liberty to exercise his feelings compatible with the possession of a like liberty in every other man. In the progress of mankind, or adaptation, the conduct which hurts necessary feelings in others must inevitably undergo restraint and consequent limitation; conduct which hurts only their incidental feelings, as those of caste or prejudice, will not inevitably be restrained, but if it springs from necessary feelings, will, on the contrary, be continued at the expense of these incidental feelings and to their final suppression. Morality is not, therefore, to be interpreted as a refraining from the infliction of any pain whatever, for some sentiment must be wounded; and by much wounding it is gradually weakened. When men mutually behave in a way that offends some essential element in the nature of each, and all in turn have to bear the consequent suffering, there will arise a tendency to curb the desire that makes them so behave.
