The more immediately, after the commission of a crime, a punishment is inflicted, the more just and useful it will be. It will be more just, because it spares the criminal the cruel and superfluous torment of uncertainty, which increases in proportion to the strength of his imagination and the sense of his weakness; and because the privation of liberty, being a punishment, ought to be inflicted before condemnation, but for as short a time as possible. Imprisonments, I say, being only the means of securing the person of the accused, until he be tried, condemned or acquitted, ought not only to be of short duration, but attended with as little severity as possible. The time should be determined by the necessary preparation for the trial, and the right of priority in the oldest prisoners. The confinement ought not to be closer than is requisite to prevent his flight, or his concealing the proofs of the crime; and the trial should be conducted with all possible expedition. Can there be a more cruel contrast than that between the indolence of a judge, and the painful anxiety of the accused; the comforts and pleasures of an insensible magistrate, and the filth and misery of the prisoner? In general, as I have before observed, The degree of the punishment, and the consequences of a crime, ought to be so contrived, as to have the greatest possible effect on others, with the least possible pain to the delinquent. If there be any society in which this is not a fundamental principle, it is an unlawful society; for mankind, by their union, originally intended to subject themselves to the least evils possible.

An immediate punishment is more useful; because the smaller the interval of time between the punishment and the crime, the stronger and more lasting will be the association of the two ideas of Crime and Punishment: so that they may be considered, one as the cause, and the other as the unavoidable and necessary effect. It is demonstrated, that the association of ideas is the cement which unites the fabric of the human intellect; without which, pleasure and pain would be simple and ineffectual sensations. The vulgar, that is, all men who have no general ideas or universal principles, act in consequence of the most immediate and familiar associations; but the more remote and complex only present themselves to the minds of those who are passionately attached to a single object, or to those of greater understanding, who have acquired an habit of rapidly comparing together a number of objects, and of forming a conclusion; and the result, that is, the action, in consequence, by these means, becomes less dangerous and uncertain.

It is, then, of the greatest importance, that the punishment should succeed the crime, as immediately as possible, if we intend, that, in the rude minds of the multitude, the seducing picture of the advantage arising from the crime, should instantly awake the attendant idea of punishment. Delaying the punishment serves only to separate these two ideas; and thus affects the minds of the spectators rather as being a terrible sight than the necessary consequence of a crime; the horror of which should contribute to heighten the idea of the punishment.

There is another excellent method of strengthening this important connection between the ideas of crime and punishment; that is, to make the punishment as analagous as possible to the nature of the crime; in order that the punishment may lead the mind to consider the crime in a different point of view, from that in which it was placed by the flattering idea of promised advantages.

Crimes of less importance are commonly punished, either in the obscurity of a prison, or the criminal is transported, to give, by his slavery, an example to societies which he never offended; an example absolutely useless, because distant from the place where the crime was committed. Men do not, in general, commit great crimes deliberately, but rather in a sudden gust of passion; and they commonly look on the punishment due to a great crime as remote and improbable. The public punishment, therefore, of small crimes will make a greater impression, and, by deterring men from the smaller, will effectually prevent the greater.
