On a careful consideration of the matter, it will appear, I think, that this abdication of self-love is not really a possible occurrence in the mind of a sane person, who still regards his own interest as the reasonable ultimate end of his actions. Such a man may, no doubt, resolve that he will devote himself unreservedly to the practice of virtue, without any particular consideration of what appears to him to be his interest: he may perform a series of acts in accordance with this resolution, and these may gradually form in him strong habitual tendencies to acts of a similar kind. But it does not seem that these habits of virtue can ever become so strong as to gain irresistible control over a sane and reasonable will. When the occasion comes on which virtue demands from such a man an extreme sacrifice--the imprudence of which must force itself upon his notice, however little he may be in the habit of weighing his own pleasures and pains--he must always be able to deliberate afresh, and to act (as far as the control of his will extends) without reference to his past actions. It may, however, be said that, though an egoist retaining his belief in rational egoism cannot thus abandon his will to the sway of moral enthusiasm, still, supposing it possible for him to change his conviction and prefer duty to interest,--or supposing we compare him with another man who makes this choice,--we shall find that a gain in happiness on the whole results from this preference. It may be held that the pleasurable emotions attendant upon such virtuous or quasi-virtuous habits as are compatible with adhesion to egoistic principles are so inferior to the raptures that attend the unreserved and passionate surrender of the soul to virtue, that it is really a man’s interest--even with a view to the present life only--to obtain, if he can, the convictions that render this surrender possible; although under certain circumstances it must necessarily lead him to act in a manner which, considered by itself, would be undoubtedly imprudent. This is certainly a tenable proposition, and I am quite disposed to think it true of persons with specially refined moral sensibilities. But--though from the imperfections of the hedonistic calculus the proposition cannot in any case be conclusively disproved--it seems, as I have said, to be opposed to the broad results of experience, so far as the great majority of mankind are concerned. Observation would lead me to suppose that most men are so constituted as to feel far more keenly pleasures (and pains) arising from some other source than the conscience; either from the gratifications of sense, or from the possession of power and fame, or from strong human affections, or from the pursuit of science, art, etc.; so that in many cases perhaps not even early training could have succeeded in giving to the moral feelings the requisite predominance: and certainly where this training has been wanting, it seems highly improbable that a mere change of ethical conviction could develop their moral susceptibilities so far as to make it clearly their earthly interest to resolve on facing all sacrifices for the fulfilment of duty.
