The distinction between the loss of consideration which a person may rightly incur by defect of prudence or of personal dignity, and the reprobation which is due to him for an offence against the rights of others, is not a merely nominal distinction. It makes a vast difference both in our feelings and in our conduct towards him, whether he displeases us in things in which we think we have a right to control him, or in things in which we know that we have not. If he displeases us, we may express our distaste, and we may stand aloof from a person as well as from a thing that displeases us; but we shall not therefore feel called on to make his life uncomfortable. We shall reflect that he already bears, or will bear, the whole penalty of his error; if he spoils his life by mismanagement, we shall not, for that reason, desire to spoil it still further: instead of wishing to punish him, we shall rather endeavour to alleviate his punishment, by showing him how he may avoid or cure the evils his conduct tends to bring upon him. He may be to us an object of pity, perhaps of dislike, but not of anger or resentment; we shall not treat him like an enemy of society: the worst we shall think ourselves justified in doing is leaving him to himself, if we do not interfere benevolently by showing interest or concern for him. It is far otherwise if he has infringed the rules necessary for the protection of his fellow-creatures, individually or collectively. The evil consequences of his acts do not then fall on himself, but on others; and society, as the protector of all its members, must retaliate on him; must inflict pain on him for the express purpose of punishment, and must take care that it be sufficiently severe. In the one case, he is an offender at our bar, and we are called on not only to sit in judgment on him, but, in one shape or another, to execute our own sentence: in the other case, it is not our part to inflict any suffering on him, except what may incidentally follow from our using the same liberty in the regulation of our own affairs, which we allow to him in his.
The distinction here pointed out between the part of a person's life which concerns only himself, and that which concerns others, many persons will refuse to admit. How (it may be asked) can any part of the conduct of a member of society be a matter of indifference to the other members? No person is an entirely isolated being; it is impossible for a person to do anything seriously or permanently hurtful to himself, without mischief reaching at least to his near connections, and often far beyond them. If he injures his property, he does harm to those who directly or indirectly derived support from it, and usually diminishes, by a greater or less amount, the general resources of the community. If he deteriorates his bodily or mental faculties, he not only brings evil upon all who depended on him for any portion of their happiness, but disqualifies himself for rendering the services which he owes to his fellow-creatures generally; perhaps becomes a burthen on their affection or benevolence; and if such conduct were very frequent, hardly any offence that is committed would detract more from the general sum of good. Finally, if by his vices or follies a person does no direct harm to others, he is nevertheless (it may be said) injurious by his example; and ought to be compelled to control himself, for the sake of those whom the sight or knowledge of his conduct might corrupt or mislead.
