Most people follow a very simple method in judging of an act. Particular modes of conduct have their traditional labels, many of which are learnt with language itself; and the moral judgment commonly consists simply in labelling the act according to certain obvious characteristics which it presents in common with others belonging to the same group. But a conscientious and intelligent judge proceeds in a different manner. He carefully examines all the details connected with the act, the external and internal conditions under which it was performed, its consequences, its motive; and, since the moral estimate in a large measure depends upon the regard paid to these circumstances, his judgment may differ greatly from that of the man in the street, even though the moral standard which they apply be exactly the same. But to acquire a full insight into all the details which are apt to influence the moral value of an act is in many cases anything but easy, and this naturally increases the disagreement. There is thus in every advanced society a diversity of opinion regarding the moral value of certain modes of conduct which results from circumstances of a purely {10} intellectual character--from the knowledge or ignorance of positive facts,--and involves no discord in principle. Now it has been assumed by the advocates of various ethical theories that all the differences of moral ideas originate in this way, and that there is some ultimate standard which must be recognised as authoritative by everybody who understands it rightly. According to Bentham, the rectitude of utilitarianism has been contested only by those who have not known their own meaning:--"When a man attempts to combat the principle of utility . . . his arguments, if they prove anything, prove not that the principle is wrong, but that, according to the applications he supposes to be made of it, it is misapplied."[9] Mr. Spencer, to whom good conduct is that "which conduces to life in each and all," believes that he has the support of "the true moral consciousness," or "moral consciousness proper," which, whether in harmony or in conflict with the "pro-ethical" sentiment, is vaguely or distinctly recognised as the rightful ruler.[10] Samuel Clarke, the intuitionist, again, is of opinion that if a man endowed with reason denies the eternal and necessary moral differences of things, it is the very same "as if a man that has the use of his sight, should at the same time that he beholds the sun, deny that there is any such thing as light in the world; or as if a man that understands Geometry or Arithmetick, should deny the most obvious and known proportions of lines or numbers."[11] In short, all disagreement as to questions of morals is attributed to ignorance or misunderstanding.
