The principles asserted in these pages must be more generally admitted as the basis for discussion of details, before a consistent application of them to all the various departments of government and morals can be attempted with any prospect of advantage. The few observations I propose to make on questions of detail, are designed to illustrate the principles, rather than to follow them out to their consequences. I offer, not so much applications, as specimens of application; which may serve to bring into greater clearness the meaning and limits of the two maxims which together form the entire doctrine of this Essay, and to assist the judgment in holding the balance between them, in the cases where it appears doubtful which of them is applicable to the case. The maxims are, first, that the individual is not accountable to society for his actions, in so far as these concern the interests of no person but himself. Advice, instruction, persuasion, and avoidance by other people if thought necessary by them for their own good, are the only measures by which society can justifiably express its dislike or disapprobation of his conduct. Secondly, that for such actions as are prejudicial to the interests of others, the individual is accountable and may be subjected either to social or to legal punishments, if society is of opinion that the one or the other is requisite for its protection. In the first place, it must by no means be supposed, because damage, or probability of damage, to the interests of others, can alone justify the interference of society, that therefore it always does justify such interference. In many cases, an individual, in pursuing a legitimate object, necessarily and therefore legitimately causes pain or loss to others, or intercepts a good which they had a reasonable hope of obtaining. Such oppositions of interest between individuals often arise from bad social institutions, but are unavoidable while those institutions last; and some would be unavoidable under any institutions. Whoever succeeds in an overcrowded profession, or in a competitive examination; whoever is preferred to another in any contest for an object which both desire, reaps benefit from the loss of others, from their wasted exertion and their disappointment. But it is, by common admission, better for the general interest of mankind, that persons should pursue their objects undeterred by this sort of consequences. In other words, society admits no rights, either legal or moral, in the disappointed competitors, to immunity from this kind of suffering; and feels called on to interfere, only when means of success have been employed which it is contrary to the general interest to permit--namely, fraud or treachery, and force.
