Cesare Beccaria

“ 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. ”

“ 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. ”

“ 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. ”
