TWO:Laws are the conditions under which men, leading independent and isolated lives, joined together in society, when tired of living in a perpetual state of war, and of enjoying a liberty which the uncertainty of its tenure rendered useless. Of this liberty they voluntarily sacrificed a part, in order to enjoy the remainder in security and quiet. The sum-total of all these portions of liberty, sacrificed for the good of each individually, constitutes the sovereignty of a nation, and the sovereign is the lawful trustee and administrator of these portions. But, besides forming this trust-fund, or deposit, it was necessary to protect it from the encroachments of individuals, whose aim it ever is not only to recover from the fund their own deposit, but to avail themselves of that contributed by others. Sensible motives, were therefore wanted to divert the despotic will of the individual from re-plunging into their primitive chaos the laws of society.[123] Such motives were found in punishments, established against transgressors of the laws; and I call them sensible motives, because experience has shown that the majority of men adopt no fixed rules of conduct, nor avoid that universal principle of dissolution, observable alike in the moral as in the physical world, save by reason of motives which directly strike the senses and constantly present themselves to the mind, counterbalancing the strong impressions of private passions, opposed as they are to the general welfare; not eloquence, nor declamations, nor the most sublime truths have ever sufficed to curb the passions for any length of time, when excited by the lively force of present objects.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.

A hydrocyclone (liquid cyclone) injects treatment solution into stationary equipment to perform separation, classification, and concentration, and is an innovative separator with a very simple structure and no drive unit.

Structure of a hydrocyclone (liquid cyclone)

A suspension containing fine particles of several micrometers or more is supplied to a cylindrical container circumferentially at high speed. And as a result it starts to rotate and a centrifugal force is generated. At this time a gravitational acceleration of several tens of thousands of G is generated in the circumferential direction, and thus leading to fast sedimentation and concentration of the fine particles. The separated concentration can be freely selected by changing the supply rate (supply pressure and flow rate) and the flow ratio of the outlet. Our hydrocyclone (liquid cyclone) was designed and manufactured to classify and concentrate fine particles, and so has a small element.

THREE:The following letter by Beccaria to the Abb Morellet in acknowledgment of the latters translation of his treatise is perhaps the best introduction to the life and character of the author. The letter in question has been quoted by Villemain in proof of the debt owed by the Italian literature of the last century to that of France, but from the allusions therein contained to Hume and the Spectator it is evident that something also was due to our own. Beccaria had spent eight years of his youth in the college of the Jesuits at Parma, with what sense of gratitude this letter will show. The following is a translation of the greater part of it:A man accused of a crime, imprisoned and acquitted, ought to bear no mark of disgrace. How many Romans, accused of the gravest crimes and then found innocent, were reverenced by the people and honoured with magisterial positions! For what reason, then, is the lot of a man innocently accused so different in our own times? Because, in the criminal system now in vogue, the idea of force and might is stronger in mens minds than the idea of justice; because accused and convicted are thrown in confusion into the same dungeon; because imprisonment is rather a mans punishment than his mere custody; and because the two forces which should be united are separated from[134] one another, namely, the internal force, which protects the laws, and the external force, which defends the throne and the nation. Were they united, the former, through the common sanction of the laws, would possess in addition a judicial capacity, although independent of that possessed by the supreme judicial power; and the glory that accompanies the pomp and ceremony of a military body would remove the infamy, which, like all popular sentiments, is more attached to the manner than the thing, as is proved by the fact that military prisons are not regarded in public estimation as so disgraceful as civil ones. There still remain among our people, in their customs and in their laws (always a hundred years, in point of merit, in arrear of the actual enlightenment of a nation), there still remain, I say, the savage impressions and fierce ideas of our ancestors of the North.

THREE:Laws should only be considered as a means of conducting mankind to the greatest happiness. The more speedily and the more nearly in connection with the crime committed punishment shall follow, the more just and useful it will be. I say more just, because a criminal is thereby spared those useless and fierce torments of suspense which are all the greater in a person of vigorous imagination and fully conscious of his own weakness; more just also, because the privation of liberty, in itself a punishment, can only precede the sentence by the shortest possible interval compatible with the requirements of necessity. Imprisonment, therefore, is simply the safe custody of a citizen pending the verdict of his guilt; and this custody, being essentially disagreeable, ought to be as brief and easy as possible. The shortness of the time should be measured both by the necessary length of the preparations for the trial and by the seniority of claim to a judgment. The strictness of confinement should be no more than is necessary either for the prevention of escape or for guarding against the concealment of the proof of crimes. The trial itself should be finished in the shortest time possible. What contrast[186] more cruel than that between a judges ease and a defendants anguish? between the comforts and pleasures of an unfeeling magistrate on the one hand, and the tears and wretchedness of a prisoner on the other? In general, the weight of a punishment and the consequence of a crime should be as efficacious as possible for the restraint of other men and as little hard as possible for the individual who is punished; for one cannot call that a proper form of society, where it is not an infallible principle, that its members intended, in constituting it, to subject themselves to as few evils as possible.
