Thus, the two writers to whom Beccaria owed most were Montesquieu and Helvetius. The Lettres Persanes of the former, which satirised so many things then in custom, contained but little about penal laws; but the idea is there started for the first time that crimes depend but little on the mildness or severity of the punishments attached to them. The imagination, says the writer, bends of itself to the customs of the country; and eight days of prison or a slight fine have as much terror for a European brought up in a country of mild manners as the loss of an arm would have for an Asiatic.[4] The Esprit des Lois, by the same author, probably contributed more to the formation of Beccarias thoughts than the Lettres Persanes, for it is impossible to read the twelfth book of that work without being struck by the resemblance of ideas. The De LEsprit of Helvetius was condemned by the Sorbonne as a combination of all the various kinds of poison scattered through modern books. Yet it was one of the most influential books of the time. We find Hume recommending it to Adam Smith for its agreeable composition father than for its philosophy; and a writer who had much in common with Beccaria drew[8] from it the same inspiration that he did. That writer was Bentham, who tells us that when he was about twenty, and on a visit to his father and stepmother in the country, he would often walk behind them reading a book, and that his favourite author was Helvetius. There are some crimes which, are at the same time frequent in society and yet difficult to prove, as adultery, pederasty, infanticide.
ONE:The opinion that each citizen should have liberty to do whatsoever is not contrary to the laws, without fear of any other inconvenience than such as may arise from the action itselfthis is the political dogma[203] that should be believed by the people and promulgated by the chief magistrates, a dogma as sacred as that of the incorrupt guardianship of the laws, without which there can be no legitimate society; a just compensation to mankind for their sacrifice of that entire liberty of action which belongs to every sensitive being, and is only limited by the extent of its force. This it is that forms liberal and vigorous souls, and enlightened minds; that makes men virtuous with that virtue which can resist fear, and not with that flexible kind of prudence which is only worthy of a man who can put up with a precarious and uncertain existence.
There is also a fourth consequence of the above principles: that the right to interpret penal laws cannot possibly rest with the criminal judges, for the[126] very reason that they are not legislators. The judges have not received the laws from our ancestors as a family tradition, as a legacy that only left to posterity the duty of obeying them, but they receive them from living society, or from the sovereign that represents it and is the lawful trustee of the actual result of mens collective wills; they receive them, not as obligations arising from an ancient oath[65] (null, because it bound wills not then in existence, and iniquitous, because it reduced men from a state of society to that of a flock), but as the result of the tacit or expressed oath made to the sovereign by the united wills of living subjects, as chains necessary for curbing and regulating the disorders caused by private interests. This is the natural and real source of the authority of the laws.To examine and distinguish all the different sorts[120] of crimes and the manner of punishing them would now be our natural task, were it not that their nature, which varies with the different circumstances of times and places, would compel us to enter upon too vast and wearisome a mass of detail. But it will suffice to indicate the most general principles and the most pernicious and common errors, in order to undeceive no less those who, from a mistaken love of liberty, would introduce anarchy, than those who would be glad to reduce their fellow-men to the uniform regularity of a convent.Is it possible, then, so beforehand to apportion punishments to crimes that when a crime is committed it shall be but necessary to refer to a code and at once detect its appropriate punishment? Or must the law be general in its language, and leave a wide margin to the discretion of the judge? Beccaria would have the judicial function confined solely to the ascertainment of the fact of a crime, its punishment preordained by the law. On the other hand it is said, that it is impossible to anticipate every case that may arise; that no two cases are ever alike; that it is better to leave the nice adjustment of penalties to the wisdom and impartiality of a judge, and only limit his discretion by rules of a most expansive description.
