In the early stages of every science, the generalizations reached are not qualified enough. The discriminating statements of the truths formulated, rise afterward, by limitation of the undiscriminating statements. As with bodily vision, which at first appreciates only the broadest traits of objects, and so leads to rude classings, which developed vision, impressible by minor differences, has to correct, so with mental vision in relation to general truths, it happens that at first the inductions, wrongly made all-embracing, have to wait for scepticism and critical observation to restrict them, by taking account of unnoticed differences. Hence, we may expect to find the current ethical conclusions too sweeping. Let us note how, in three ways, these dominant beliefs, alike of professed moralists and of people at large, are made erroneous by lack of qualifications. In the first place, the authority of the lower feelings as guides is by no means always inferior to the authority of the higher feelings, but is often superior. Daily occur occasions on which sensations must be obeyed rather than sentiments. Let any one think of sitting all night naked in a snow-storm, or going a week without food, or letting his head be held under water for ten minutes, and he will see that the pleasures and pains directly related to maintenance of life may not be wholly subordinated to the pleasures and pains indirectly related to maintenance of life. Though in many cases guidance by the simple feelings rather than by the complex feelings is injurious, in other cases guidance by the complex feelings rather than by the simple feelings is fatal; and throughout a wide range of cases their relative authorities as guides are indeterminate. Grant that in a man pursued, the protesting feelings accompanying intense and prolonged effort, must, to preserve life, be overruled by the fear of his pursuers; it may yet happen that, persisting till he drops, the resulting exhaustion causes death, though, the pursuit having been abandoned, death would not otherwise have resulted. Grant that a widow left in poverty must deny her appetite that she may give enough food to her children to keep them alive; yet the denial of her appetite pushed too far may leave them not only entirely without food but without guardianship. Grant that, working his brain unceasingly from dawn till dark, the man in pecuniary difficulties must disregard rebellious bodily sensations in obedience to the conscientious desire to liquidate the claims on him; yet he may carry this subjection of simple feelings to complex feelings to the extent of shattering his health, and failing in that end which, with less of this subjection, he might have achieved. Clearly, then, the subordination of lower feelings must be a conditional subordination. The supremacy of higher feelings must be a qualified supremacy.
