I fully admit that the mischief which a person does to himself may seriously affect, both through their sympathies and their interests, those nearly connected with him and, in a minor degree, society at large. When, by conduct of this sort, a person is led to violate a distinct and assignable obligation to any other person or persons, the case is taken out of the self-regarding class, and becomes amenable to moral disapprobation in the proper sense of the term. If, for example, a man, through intemperance or extravagance, becomes unable to pay his debts, or, having undertaken the moral responsibility of a family, becomes from the same cause incapable of supporting or educating them, he is deservedly reprobated, and might be justly punished; but it is for the breach of duty to his family or creditors, not for the extravagance. If the resources which ought to have been devoted to them, had been diverted from them for the most prudent investment, the moral culpability would have been the same. George Barnwell murdered his uncle to get money for his mistress, but if he had done it to set himself up in business, he would equally have been hanged.
Again, in the frequent case of a man who causes grief to his family by addiction to bad habits, he deserves reproach for his unkindness or ingratitude; but so he may for cultivating habits not in themselves vicious, if they are painful to those with whom he passes his life, who from personal ties are dependent on him for their comfort. Whoever fails in the consideration generally due to the interests and feelings of others, not being compelled by some more imperative duty, or justified by allowable self-preference, is a subject of moral disapprobation for that failure, but not for the cause of it, nor for the errors, merely personal to himself, which may have remotely led to it. In like manner, when a person disables himself, by conduct purely self-regarding, from the performance of some definite duty incumbent on him to the public, he is guilty of a social offence.
No person ought to be punished simply for being drunk; but a soldier or a policeman should be punished for being drunk on duty. Whenever, in short, there is a definite damage, or a definite risk of damage, either to an individual or to the public, the case is taken out of the province of liberty, and placed in that of morality or law.
But with regard to the merely contingent, or, as it may be called, constructive injury which a person causes to society, by conduct which neither violates any specific duty to the public, nor occasions perceptible hurt to any assignable individual except himself; the inconvenience is one which society can afford to bear, for the sake of the greater good of human freedom. If grown persons are to be punished for not taking proper care of themselves, I would rather it were for their own sake, than under pretence of preventing them from impairing their capacity or rendering to society benefits which society does not pretend it has a right to exact. But I cannot consent to argue the point as if society had no means of bringing its weaker members up to its ordinary standard of rational conduct, except waiting till they do something irrational, and then punishing them, legally or morally, for it. Society has had absolute power over them during all the early portion of their existence: it has had the whole period of childhood and nonage in which to try whether it could make them capable of rational conduct in life. The existing generation is master both of the training and the entire circumstances of the generation to come; it cannot indeed make them perfectly wise and good, because it is itself so lamentably deficient in goodness and wisdom; and its best efforts are not always, in individual cases, its most successful ones; but it is perfectly well able to make the rising generation, as a whole, as good as, and a little better than, itself. If society lets any considerable number of its members grow up mere children, incapable of being acted on by rational consideration of distant motives, society has itself to blame for the consequences. Armed not only with all the powers of education, but with the ascendency which the authority of a received opinion always exercises over the minds who are least fitted to judge for themselves;and aided by the natural penalties which cannot be prevented from falling on those who incur the distaste or the contempt of those who know them; let not society pretend that it needs, besides all this, the power to issue commands and enforce obedience in the personal concerns of individuals, in which, on all principles of justice and policy, the decision ought to rest with those who are to abide the consequences.
