To these intuitionists, and to the popular mind very often, the approval or disapproval of conscience is immediate, intuitive, and unerring. Its authority is absolute and not to be questioned. We have this faculty within us that tells us as surely what is right and what wrong as our color-sense tells us what is red and what green. Some people may, to be sure, be color-blind, or have defective consciences; but the great mass of unsophisticated people possess this innate guide and commandment, a quite sufficient warrant for all our distinctions of good and evil. Honest men do not really differ in their moral judgments. They may misunderstand one another's concepts and engage in verbal disputes; but at bottom their moral sense approves and disapproves the same acts. Our moral differences come mainly from the deluding effects of passion and the sophisticated ingenuities of the intellect. We should "return to nature," go by ourselves alone, and listen to the inner voice. If we sincerely listen and obey we shall always do right. [Footnote: "But truth and right, founded in the eternal and, is what every man can judge of, when laid before him. 'T is necessarily one and the same to every man's understanding, just as light is the same, to every man's eyes." (S. Clarke, Discourse upon Natural Religion, 1706.)] We cannot but recognize a certain amount of practical truth in this picture. But it is over-simplified, and it is fundamentally unsatisfactory to the intellect. We shall now pass in review its most obvious inadequacies. Do the deliverances of different people's consciences agree?
