THREE: Our laws prohibit suggestive (leading) questions in a lawsuit: those, that is (according to the doctors of law), which, instead of applying, as they should do,[145] to the genus in the circumstances of a crime, refer to the species; those, in other words, which from their immediate connection with a crime suggest to the accused a direct answer. Questions, according to the criminal lawyers, ought, so to speak, to envelop the main fact spirally and never to attack it in a direct line. The reasons for this method are, either that an answer may not be suggested to the accused which may place him face to face with the charge against him, or perhaps because it seems unnatural for him directly to criminate himself. But, whichever of these reasons it may be, the contradiction is remarkable between the existence of such a custom and the legal authorisation of torture; for what interrogatory can be more suggestive than pain? The former reason applies to the question of torture, because pain will suggest to a strong man obstinate silence, in order that he may exchange the greater penalty for the lesser, whilst it will suggest to a weak man confession, in order that he may escape from present torment, which has more influence over him than pain which is to come. The other reason evidently applies too, for if a special question leads a man to confess against natural right, the agonies of torture will more easily do the same. But men are more governed by the difference of names than by that of things.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.
