On Liberty

crime, they are not bound to look on inactive until the crime is committed, but may interfere to prevent it. If poisons were never bought or used for any purpose except the commission of murder, it would be right to prohibit their manufacture and sale. They may, however, be wanted not only for innocent but for useful purposes, and restrictions cannot be imposed in the one case without operating in the other. Again, it is a proper office of public authority to guard against accidents. If either a public officer or any one else saw a person attempting to cross a bridge which had been ascertained to be unsafe, and there were no time to warn him of his danger, they might seize him and turn him back, without any real infringement of his liberty; for liberty consists in doing what one desires, and he does not desire to fall into the river. Nevertheless, when there is not a certainty, but only a danger of mischief, no one but the person himself can judge of the sufficiency of the motive which may prompt him to incur the risk: in this case, therefore (unless he is a child, or delirious, or in some state of excitement or absorption incompatible with the full use of the reflecting faculty), he ought, I conceive, to be only warned of the danger; not forcibly prevented from[Pg 183] exposing himself to it. Similar considerations, applied to such a question as the sale of poisons, may enable us to decide which among the possible modes of regulation are or are not contrary to principle. Such a precaution, for example, as that of labelling the drug with some word expressive of its dangerous character, may be enforced without violation of liberty: the buyer cannot wish not to know that the thing he possesses has poisonous qualities. But to require in all cases the certificate of a medical practitioner, would make it sometimes impossible, always expensive, to obtain the article for legitimate uses. The only mode apparent to me, in which difficulties may be thrown in the way of crime committed through this means, without any infringement, worth taking into account, upon the liberty of those who desire the poisonous substance for other purposes, consists in providing what, in the apt language of Bentham, is called "preappointed evidence." This provision is familiar to every one in the case of contracts. It is usual and right that the law, when a contract is entered into, should require as the condition of its enforcing performance, that certain formalities should be observed, such as signatures, attestation of witnesses, and the like, in order that in case of subsequent dispute, there may be[Pg 184] evidence to prove that the contract was really entered into, and that there was nothing in the circumstances to render it legally invalid: the effect being, to throw great obstacles in the way of fictitious contracts, or contracts made in circumstances which, if known, would destroy their validity. Precautions of a similar nature might be enforced in the sale of articles adapted to be instruments of crime. The seller, for example, might be required to enter into a register the exact time of the transaction, the name and address of the buyer, the precise quality and quantity sold; to ask the purpose for which it was wanted, and record the answer he received. When there was no medical prescription, the presence of some third person might be required, to bring home the fact to the purchaser, in case there should afterwards be reason to believe that the article had been applied to criminal purposes. Such regulations would in general be no material impediment to obtaining the article, but a very considerable one to making an improper use of it without detection. The right inherent in society, to ward off crimes against itself by antecedent precautions, suggests the obvious limitations to the maxim, that purely self-regarding misconduct cannot properly be[Pg 185] meddled with in the way of prevention or punishment. Drunkenness, for example, in ordinary cases, is not a fit subject for legislative interference; but I should deem it perfectly legitimate that a person, who had once been convicted of any act of violence to others under the influence of drink, should be placed under a special legal restriction, personal to himself; that if he were afterwards found drunk, he should be liable to a penalty, and that if when in that state he committed another offence, the punishment to which he would be liable for that other offence should be increased in severity. The making himself drunk, in a person whom drunkenness excites to do harm to others, is a crime against others. So, again, idleness, except in a person receiving support from the public, or except when it constitutes a breach of contract, cannot without tyranny be made a subject of legal punishment; but if either from idleness or from any other avoidable cause, a man fails to perform his legal duties to others, as for instance to support his children, it is no tyranny to force him to fulfil that obligation, by compulsory labour, if no other means are available. Again, there are many acts which, being directly injurious only to the agents themselves, ought not to be legally interdicted, but which, if done[Pg 186] publicly, are a violation of good manners and coming thus within the category of offences against others may rightfully be prohibited. Of this kind are offences against decency; on which it is unnecessary to dwell, the rather as they are only connected indirectly with our subject, the objection to publicity being equally strong in the case of many actions not in themselves condemnable, nor supposed to be so. There is another question to which an answer must be found, consistent with the principles which have been laid down. In cases of personal conduct supposed to be blamable, but which respect for liberty precludes society from preventing or punishing, because the evil directly resulting falls wholly on the agent; what the agent is free to do, ought other persons to be equally free to counsel or instigate? This question is not free from difficulty. The case of a person who solicits another to do an act, is not strictly a case of self-regarding conduct. To give advice or offer inducements to any one, is a social act, and may therefore, like actions in general which affect others, be supposed amenable to social control. But a little reflection corrects the first impression, by showing that if the case is not strictly within the definition of individual liberty, yet the reasons[Pg 187] on which the principle of individual liberty is grounded, are applicable to it. If people must be allowed, in whatever concerns only themselves, to act as seems best to themselves at their own peril, they must equally be free to consult with one another about what is fit to be so done; to exchange opinions, and give and receive suggestions. Whatever it is permitted to do, it must be permitted to advise to do. The question is doubtful, only when the instigator derives a personal benefit from his advice; when he makes it his occupation, for subsistence or pecuniary gain, to promote what society and the state consider to be an evil. Then, indeed, a new element of complication is introduced; namely, the existence of classes of persons with an interest opposed to what is considered as the public weal, and whose mode of living is grounded on the counteraction of it. Ought this to be interfered with, or not? Fornication, for example, must be tolerated, and so must gambling; but should a person be free to be a pimp, or to keep a gambling-house? The case is one of those which lie on the exact boundary line between two principles, and it is not at once apparent to which of the two it properly belongs. There are arguments on both sides. On the side of toleration it may be said, that the fact[Pg 188] of following anything as an occupation, and living or profiting by the practice of it, cannot make that criminal which would otherwise be admissible; that the act should either be consistently permitted or consistently prohibited; that if the principles which we have hitherto defended are true, society has no business, as society, to decide anything to be wrong which concerns only the individual; that it cannot go beyond dissuasion, and that one person should be as free to persuade, as another to dissuade. In opposition to this it may be contended, that although the public, or the State, are not warranted in authoritatively deciding, for purposes of repression or punishment, that such or such conduct affecting only the interests of the individual is good or bad, they are fully justified in assuming, if they regard it as bad, that its being so or not is at least a disputable question: That, this being supposed, they cannot be acting wrongly in endeavouring to exclude the influence of solicitations which are not disinterested, of instigators who cannot possibly be impartial—who have a direct personal interest on one side, and that side the one which the State believes to be wrong, and who confessedly promote it for personal objects only. There can surely, it may be urged, be nothing lost, no sacrifice of good, by[Pg 189] so ordering matters that persons shall make their election, either wisely or foolishly, on their own prompting, as free as possible from the arts of persons who stimulate their inclinations for interested purposes of their own. Thus (it may be said) though the statutes respecting unlawful games are utterly indefensible—though all persons should be free to gamble in their own or each other's houses, or in any place of meeting established by their own subscriptions, and open only to the members and their visitors—yet public gambling-houses should not be permitted. It is true that the prohibition is never effectual, and that whatever amount of tyrannical power is given to the police, gambling-houses can always be maintained under other pretences; but they may be compelled to conduct their operations with a certain degree of secrecy and mystery, so that nobody knows anything about them but those who seek them; and more than this, society ought not to aim at. There is considerable force in these arguments; I will not venture to decide whether they are sufficient to justify the moral anomaly of punishing the accessary, when the principal is (and must be) allowed to go free; or fining or imprisoning the procurer, but not the fornicator, the gambling-house keeper, but not the gambler.[Pg 190] Still less ought the common operations of buying and selling to be interfered with on analogous grounds. Almost every article which is bought and sold may be used in excess, and the sellers have a pecuniary interest in encouraging that excess; but no argument can be founded on this, in favour, for instance, of the Maine Law; because the class of dealers in strong drinks, though interested in their abuse, are indispensably required for the sake of their legitimate use. The interest, however, of these dealers in promoting intemperance is a real evil, and justifies the State in imposing restrictions and requiring guarantees, which but for that justification would be infringements of legitimate liberty. A further question is, whether the State, while it permits, should nevertheless indirectly discourage conduct which it deems contrary to the best interests of the agent; whether, for example, it should take measures to render the means of drunkenness more costly, or add to the difficulty of procuring them, by limiting the number of the places of sale. On this as on most other practical questions, many distinctions require to be made. To tax stimulants for the sole purpose of making them more difficult to be obtained, is a measure differing only in degree from their entire [Pg 191]prohibition; and would be justifiable only if
