TWO: Wise governments suffer not political idleness in the midst of work and industry. I mean by political idleness that existence which contributes nothing to society either by its work or by its wealth; which gains without ever losing; which, stupidly admired and reverenced by the vulgar, is regarded by the wise man with disdain, and with pity for the beings who are its victims; which, being destitute of that stimulus of an active life, the necessity of preserving or increasing[222] the store of worldly goods, leaves to the passions of opinion, not the least strong ones, all their energy. This kind of idleness has been confused by austere declaimers with that of riches, gathered by industry; but it is not for the severe and narrow virtue of some censors, but for the laws, to define what is punishable idleness. He is not guilty of political idleness, who enjoys the fruits of the virtues or vices of his ancestors and sells in exchange for his pleasures bread and existence to the industrious poor, who carry on peacefully the silent war of industry against wealth, instead of by force a war uncertain and sanguinary. The latter kind of idleness is necessary and useful, in proportion as society becomes wider and its government more strict.CHAPTER XVI. CAPITAL PUNISHMENT.

Hydrocyclone (liquid cyclone)02

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:
  • Equipment costs can be reduced.
  • Operating costs can be reduced.
  • Maintenance costs can be reduced.
  • Any change in raw material and product can be easily addressed.
  • Large amounts can be treated in a small area.
  • Separation and cleaning are easy because of the simple structure.
  • Simplified control
  • This equipment can be operated in synchronization with external devices.
  • Alarm and interlock mechanism.
THREE:In order that a punishment may be just, it must contain only such degrees of intensity as suffice to deter men from crimes. But as there is no one who on reflection would choose the total and perpetual loss of his liberty, however great the advantages offered him by a crime, the intensity of the punishment of servitude for life, substituted for capital punishment, has that in it which is sufficient to daunt the most determined courage. I will add that it is even more deterrent than death. Very many men face death calmly and firmly, some from fanaticism, some from vanity, which almost always attends a man to the tomb; others from a last desperate attempt either no longer to live or to escape from their misery; but neither fanaticism nor vanity have any place among fetters and chains, under the stick, under the yoke, in a cage of iron; the wretch thus punished is so far from terminating his miseries that with his punishment he only begins them. Smuggling is a real crime against the sovereign and the nation; but its punishment should not be one of disgrace, because its commission incurs no disgrace in public opinion.
