TWO:DAlembert, 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[6] 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.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.

Great attention is recently being paid to global environmental issues, and it is now conceivable that companies will need to treat used solvents themselves. In consideration of this kind of social issue, we have developed a “membrane separation type solvent dehydration system,” which uses a polyimide membrane with superior dehydration properties developed by Ube Industries, Ltd. in combination with our own distillation and concentration technology that has resulted in solvents being more easily recovered.
THREE:
- 1Under the distillation system, even in case of azeotropic solvent compositions, this system which remove water vapor by the polyimide membrane will easily dehydrate.
- 2In comparison with the distillation system, it significantly saves on use of steam.
- 3Dehydration can be performed through merely supplying evaporated vapor to the membrane module and maintaining the differential pressure between the permeable side and the impermeable side.
- 4Solvent purity of 99.9% or more can be achieved by carrying out dehydration with a polyimide membrane only.
- 5The polyimide membrane has superior heat and solvent resistance. Therefore, the vapor permeation system reduces contamination of the membrane and thus extends its life.
THREE:The following is the kind of reasoning adopted[175] by the thief or the assassin, whose only motives for not breaking the laws are the gallows or the wheel. (I know that the analysis of ones own thoughts is an art only learnt by education, but a thief does not the less act according to certain principles because he is unable to express them). Of what sort, he argues, are these laws that I am bound to observe, that leave so great an interval between myself and the rich man? He denies me the penny I ask of him, and excuses himself by ordering from me a work of which he himself knows nothing. Who has made these laws? Were they not made by rich and powerful men, who have never deigned to visit the wretched hovels of the poor, who have never divided a musty loaf of bread amid the innocent cries of famished children and the tears of a wife? Let us break these bonds, which are fatal to the greater number, and only useful to a few indolent tyrants; let us attack injustice in its source. I will return to my state of natural independence; I will live for some time happy and free on the fruits of my courage and address; and if the day should ever come when I have to suffer and repent for it, the time of suffering will be short, and I shall have one day of misery for many years of liberty and pleasure. As the king of a small band, I will correct the errors of fortune, and see these tyrants pale and tremble before one, whom in their insolent arrogance they rated lower than their[176] horses or their dogs. Then religion hovers before the mind of the criminal, who turns everything to a bad use, and offering him a facile repentance and an almost certain eternity of bliss does much to diminish in his eyes the horror of that last tragedy of all.
The aromatic polyimide membrane is highly permeable to water vapor but less permeable to vapors of organic compounds such as alcohol etc.
THREE:Penalties of infamy ought neither to be too common, nor to fall upon too many persons at a time; not too common, because the real and too frequent effects of matters of opinion weaken the force of opinion itself; not too general, because the disgrace of many persons resolves itself into the disgrace of none of them.It would appear at first sight that there could be[71] little to say about crimes and punishments, so obvious and self-evident seem the relations that exist between them. Many people still believe in an innate sense of justice in mankind, sufficient always to prevent wide aberrations from equity. Is it, they might ask, conceivable that men should ever lose sight of the distinction between the punishment of guilt and the punishment of innocence?that they should ever punish one equally with the other? Yet there is no country in the world which in its past or present history has not involved the relations of a criminal in the punishment inflicted on him; and in savage countries generally it is still common to satisfy justice with vengeance on some blood-relation of a malefactor who escapes from the punishment due to his crime.
- 1 Recovery of the detergent solvent Recovery of the cleaning solvent such as electronic parts industry, precision instrument industry.
- 2Solvent recovery and the refinement Solvent recovery and the refinement such as chemical industry, an industry of medical supplies, food industry, the fermentation industry.
THREE:Men oppose the strongest barriers against open tyranny, but they see not the imperceptible insect, which gnaws them away, and makes for the invading stream an opening that is all the more sure by very reason of its concealment from view.That the scruple to convict diminishes the certainty of punishment, and therefore raises hopes of impunity, is illustrated by the case of two American brothers who, desirous to perpetrate a murder, waited till their victim had left their State, in which capital punishment had been abolished, and had betaken himself to a State which still retained it, before they ventured to execute their criminal intention. That such reluctance to convict is often most injurious to[42] the public is proved by the case of a woman at Chelmsford who some years ago was acquitted, in spite of strong evidence, on a charge of poisoning, and who, before her guilt was finally proved, lived to poison several other persons who would otherwise have escaped her arts.[27]
