D’Alembert, Diderot, Helvetius, Buffon, Hume, illustrious names, which no one can hear without emotion! Your immortal works are my continual study, the object of my occupation by day, of my meditation in the silence of night. Full of the truth which you teach, how could I ever have burned incense to worshipped error, or debased myself to lie to posterity? I find myself rewarded beyond my hopes in the signs of esteem I have received from these celebrated persons, my masters. Convey to each of these, I pray you, my most humble thanks, and assure them that I feel for them that profound and true respect which a feeling soul entertains for truth and virtue.

My occupation is to cultivate philosophy in peace, and so to satisfy my three strongest passions, the love, that is, of literary fame, the love of liberty, and pity for the ills of mankind, slaves of so many errors. My conversion to philosophy only dates back five years, and I owe it to my perusal of the ‘Lettres Persanes.’ The second work that completed my mental revolution was that of Helvetius. The latter forced me irresistibly into the way of truth, and aroused my attention for the first time to the blindness and miseries of humanity.

… I lead a tranquil and solitary life, if a select company of friends in which the heart and mind are in continual movement can be called solitude. This is my consolation, and prevents me feeling in my own country as if I were in exile.

My country is quite immersed in prejudices, left in it by its ancient masters. The Milanese have no pardon for those who would have them live in the eighteenth century. In a capital which counts 120,000 inhabitants, you will scarcely find twenty who love to instruct themselves, and who sacrifice to truth and virtue. My friends and I, persuaded that periodical works are among the best means for tempting to some sort of reading minds incapable of more serious application, are publishing in papers, after the manner of the English ‘Spectator,’ a work which in England has contributed so much to increase mental culture and the progress of good sense. The French philosophers have a colony in this America, and we are their disciples because we are the disciples of reason, &c.

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 Beccaria’s 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 L’Esprit’ 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 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.

The influence of the predominant French philosophy appears throughout Beccaria’s treatise. Human justice is based on the idea of public utility, and the object of legislation is to conduct men to the greatest possible happiness or to the least possible misery. The vein of dissatisfaction with life and of disbelief in human virtue is a marked feature of Beccaria’s philosophy. To him life is a desert, in which a few physical pleasures lie scattered here and there;[5] his own country is only a place of exile, save for the presence of a few friends engaged like himself in a war with ignorance. Human ideas of morality and virtue have only been produced in the course of many centuries and after much bloodshed, but slow and difficult as their growth has been, they are ever ready to disappear at the slightest breeze that blows against them.

Beccaria entertains a similar despair of truth. The history of mankind represents a vast sea of errors, in which at rare intervals a few truths only float uppermost; and the durability of great truths is as that of a flash of lightning when compared with the long and dark night which envelops humanity. For this reason he is ready to be the servant of truth, not her martyr; and he recommends in the search for truth, as in the other affairs of life, a little of that ‘philosophical indolence’ which cares not too much about results, and which a writer like Montaigne is best fitted to inspire.[6]

The few select friends who made life at Milan just supportable were Pietro and Alessandro Verri, Frisi, and some others. Pietro Verri was ten years older than Beccaria, and it was at his instance that the latter wrote his first treatise on a subject which then demanded some attention, namely, ‘The Disorders and Remedies of the Coinage.’ This work was published two years before the ‘Crimes and Punishments,’ but though it provoked much discussion at the time, it has long since ceased to have any interest.

Count Pietro Verri was the son of Gabriel, who was distinguished alike for his legal knowledge and high position in Milan. At the house of Pietro, Beccaria and the other friends used to meet for the discussion and study of political and social questions. Alessandro, the younger brother of Pietro, held the office of ‘Protector of Prisoners,’ an office which consisted in visiting the prisons, listening to the grievances of the inmates, and discovering, if possible, reasons for their defence or for mercy. The distressing sights he was witness of in this capacity are said to have had the most marked effect upon him; and there is no doubt that this fact caused the attention of the friends to be so much directed to the state of the penal laws. It is believed to have been at the instigation of the two brothers that Beccaria undertook the work which was destined to make his name so famous.

Why then did Pietro Verri not write it himself? The answer would seem to be, out of deference for the position and opinions of his father. It was some time later that Gabriel defended the use of torture in the Milanese Senate, and Pietro wrote a work on torture which he did not publish in his father’s lifetime. It was probably due also to the father’s position that Alessandro held his office of Protector of the Prisoners, so that there were obvious reasons which prevented either brother from undertaking the work in question.
