Intuitionalism carried out to logical extremes is represented by such men as Tclstoy, and, in general, those who genuinely and persistently act according to the dictates of their conscience, "who hold, and so far as they can, act upon the principle that we must never resist force by force, never arrest a thief, must literally give to him that asketh, up to one's last penny, and so on."
Empiricism. To explain the grounds of the Empirical position is to exhibit the arguments in refutation of Intuitionalism. The most obvious and frequent line of attack that empirical moralists make upon Intuitionalism is to examine and compare the various "intuitions" of right conduct which have been held by men in different ages and places.
The traditional method of combating intuitionalism from the time of John Locke to that of Herbert Spencer has been to present the reader with a list of cruel and abominable savage customs, ridiculous superstitions, acts of religious fanaticism and intolerance, which have all alike seemed self-evidently good and right to the peoples or individuals who have practised them. There is hardly a vice or a crime (according to our own moral standard) which has not at some time or other in some circumstances been looked upon as a moral and religious duty. Stealing was accounted virtuous for the young Spartan, and among the Indian caste of Thugs. In the ancient world, piracy, that is, robbery and murder, was a respectable profession. To the mediæval Christian, religious persecution was the highest of duties, and so on.[1]
[Footnote 1: Rashdall: loc. cit., p. 59.]
The Empiricist asks: If all these intuitions are absolute; if men at various times and at various places, indeed, if, as is the case, men of different social classes and situations at the present time, differ so profoundly in their "intuitions" of the just, the noble, and the base, which of the conflicting intuitions, all equally absolute, is the absolute? The Intuitionalist continually appeals to the universal intuition and assent of Mankind. But there is scarcely a single moral law for which universal assent in even a single generation can be found. One has but to survey the heterogeneous collection of customs and prohibitions collected in such a work as Frazer's Golden Bough, to see how little unanimity there is in the moral intuitions of mankind.
The Empiricist finds the origin of these divergent moral convictions in the divergent environments to which individuals in different places, times, and social situations are exposed. The intensity and apparent irrefutability of these convictions, which the Intuitionalist ascribes to their innateness, the Empiricist ascribes to their early acquisition, and the deep emotional hold which early acquired habits have over the individual. Those moral beliefs which we hold with the utmost conviction and intensity are, instead of being thereby guaranteed as most reasonable and genuinely moral, thereby rendered, says the Empiricist, the more suspect. They are evidences of the effectiveness of our early education, or of our high degree of sensitiveness to our fellows. Conscience is thus reduced to habitual emotional reactions produced by the contact of a given individual temperament with a given environment.
Thus acts come by the individual to be recognized as right or wrong, according to the tradition to which he has been educated and the contacts with other people to which he is continually exposed. The Empiricist does not deny that there are intuitions, or apparent intuitions. He denies their ultimacy, their unquestionable validity.
When ... we find ourselves entertaining an opinion about the basis of which there is a quality of feeling which tells us that to inquire into it would be absurd, obviously unnecessary, unprofitable, undesirable, bad form, or wicked, we may know that that opinion is a non-rational one, and probably, therefore, founded upon inadequate evidence.[1]
[Footnote 1: Trotter: Instincts of the Herd, p. 44.]
These so powerful convictions are the immediate promptings of instincts, or of the habits into which they have been modified. The humane Christian, had he been brought up in the Eskimo tradition, would with the most tender solicitude slaughter his aged parents, just as the humane Christian in the Middle Ages thought it his duty to slay heretics. There is no limit to the excesses to which men have gone on the dictates of conscience. To put actions on the basis of conscience is to put them beyond the control of reflection or the check of inquiry. It is to reduce conduct to caprice; to exalt impulse into a moral command. And the results of accepting blind intuitions as rational knowledge have been in many cases catastrophic.
