Here, however, a subtle question arises. For the assumption on which this treatise proceeds is that there are several ultimate ends of action, which all claim to be rational ends, such as every man ought to adopt. Hence, if Wisdom implies right judgment as to ends, it is clear that a person who regards some one end as the sole right or rational ultimate end will not consider a man wise who adopts any other ultimate end. Can we say then that in the common use of the word Wisdom any one ultimate end is distinctly implied to the exclusion of others? It may be suggested, perhaps, that in the moral view of Common Sense which we are now trying to make clear, since Wisdom itself is prescribed or commended as a quality of conduct intuitively discerned to be right or good, the ultimate end which the wise man prefers must be just this attainment of rightness or goodness in conduct generally; rather than pleasure for himself or others, or any other ulterior end. I think, however, that in the case of this notion it is impossible to carry out that analysis of ordinary practical reasoning into several distinct methods, each admitting and needing separate development, upon which the plan of this treatise is founded. For, as we saw, it is characteristic of Common Sense to assume coincidence or harmony among these different competing methods. And hence, while as regards most particular virtues and duties, the exercise of moral judgment in ordinary men is _prima facie_ independent of hedonistic calculations, and occasionally in apparent conflict with their results,--so that the reconciliation of the different procedures presents itself as a problem to be solved--in the comprehensive notion of Wisdom the antagonism is latent. Common Sense seems to mean by a Wise man, a man who attains at once all the different rational ends; who by conduct in perfect conformity with the true moral code attains the greatest happiness possible both for himself and for mankind (or that portion of mankind to which his efforts are necessarily restricted). But if we find this harmony unattainable,--if, for example, Rational Egoism seems to lead to conduct opposed to the true interests of mankind in general, and we ask whether we are to call Wise the man who seeks, or him who sacrifices, his private interests,--Common Sense gives no clear reply.
