All that has been said in the course of this work, proves clearly that every thing is necessary; that every thing is always in order, relatively to Nature; where all beings do nothing more than follow the laws that are imposed on their respective classes. It is part of her plan, that certain portions of the earth shall bring forth delicious fruits, shall blossom beauteous flowers; whilst others shall only furnish brambles, shall yield nothing but noxious vegetables: she has been willing that some societies should produce wise men, great heroes; that others should only give birth to abject souls, contemptible men, without energy, destitute of virtue. Passions, winds, tempests, hurricanes, volcanoes, wars, plagues, famines, diseases, death, are as necessary to her eternal march as the beneficent heat of the sun, the serenity of the atmosphere, the gentle showers of spring, plentiful years, peace, health, harmony, life: vice and virtue, darkness and light, and science are equally necessary; the one are not benefits, the other are not evils, except for those beings whose happiness they influence by either favouring or deranging their peculiar mode of existence. _The whole cannot be miserable, but it may contain unhappy individuals._ Nature, then, distributes with the same hand that which is called _order_, and that which is called _disorder_; that which is called _pleasure_, and that which is called _pain_: in short, she diffuses by the necessity of her existence, good and evil in the world we inhabit. Let not man, therefore, either arraign her bounty, or tax her with malice; let him not imagine that his feeble cries, his weak supplications, can never arrest her colossal power, always acting after immutable laws; let him submit silently to his condition; and when he suffers, let him not seek a remedy by recurring to chimeras that his own distempered imagination has created; let him draw from the stores of Nature herself, the remedies which she offers for the evil she brings upon him: if she sends him diseases, let him search in her bosom for those salutary productions to which she has given birth, which will cure them: if she gives him errors, she also furnishes him with experience to counteract them; in truth, she supplies him with an antidote suitable to destroy their fatal effects. If she permits man to groan under the pressure of his vices, beneath the load of his follies, she also shews him in virtue, a sure remedy for his infirmities: if the evils that some societies experience are necessary, when they shall have become too incommodious they will be irresistibly obliged to search for those remedies which Nature will always point out to them. If this Nature has rendered existence insupportable, to some unfortunate beings, whom she appears to have selected for her victims, still death, is a door that will surely be opened to them--that will deliver them from their misfortunes, although in their puny, imbecile, wayward judgment, they
