The happy man is he who knows how to enjoy the benefits bestowed upon him by nature: in other words, he who thinks for himself; who is thankful for the good he possesses; who does not envy the welfare of others, nor sigh after imaginary benefits always beyond his grasp.
The unhappy man is he who is incapacitated to enjoy the benefits of nature; that is, he who suffers others to think for him; who neglects the absolute good he possesses, in a fruitless search after ideal benefits; who vainly sighs after that which ever eludes his pursuit.
It necessarily results, that man in his enquiry ought always to contemplate experience, and natural philosophy: These are what he should consult in his religion,—in his morals,—in his legislation,—in his political government,—in the arts,—in the sciences,—in his pleasures,—above all, in his misfortunes. Experience teaches that Nature acts by simple, regular, and invariable laws. It is by his senses, man is bound to this universal Nature; it is by his perception he must penetrate her secrets; it is from his senses he must draw experience of her laws. Therefore, whenever he neglects to acquire experience or quits its path, he stumbles into an abyss; his imagination leads him astray.
All the errors of man are physical: he never deceives himself but when he neglects to return back to nature, to consult her laws, to call practical knowledge to his aid. It is for want of practical knowledge he forms such imperfect ideas of matter, of its properties, of its combinations, of its power, of its mode of action, and of the energies which spring from its essence. Wanting this experience, the whole universe, to him, is but one vast scene of error. The most ordinary results appear to him the most astonishing phenomena; he wonders at every thing, understands nothing, and yields the guidance of his actions to those interested in betraying his interests. He is ignorant of Nature, and he has mistaken her laws; he has not contemplated the necessary routine which she has marked out for every thing she holds. Mistaken the laws of Nature, did I say? He has mistaken himself: the consequence is, that all his systems, all his conjectures, all his reasonings, from which he has banished experience, are nothing more than a tissue of errors, a long chain of inconsistencies.
Error is always prejudicial to man: it is by deceiving himself, the human race is plunged into misery. He neglected Nature; he did not comprehend her laws; he formed gods of the most preposterous and ridiculous kinds: these became the sole objects of his hope, and the creatures of his fear: he was unhappy, he trembled under these visionary deities; under the supposed influence of visionary beings created by himself; under the terror inspired by blocks of stone; by logs of wood; by flying fish; or the frowns of men, mortal as himself, whom his disturbed fancy had elevated above that Nature of which alone he is capable of forming any idea. His very posterity laughs at his folly, because experience has convinced them of the absurdity of his groundless fears—of his misplaced worship. Thus has passed away the ancient mythology, with all the trifling and nonsensical attributes attached to it by ignorance.
Not understanding that Nature, equal in her distributions, entirely destitute of malice, follows only necessary and immutable laws, when she either produces beings or destroys them, when she causes those to suffer, whose construction creates sensibility; when she scatters among them good and evil; when she subjects them to incessant change—he did not perceive it was in the breast of Nature herself, that it was in her exuberance he ought to seek to satisfy his deficiencies; for remedies against his pains; for the means of rendering himself happy: he expected to derive these benefits from fantastic beings, whom he supposed to be above Nature; whom he mistakingly imagined to be the authors of his pleasures, and the cause of his misfortunes. From hence it appears that to his ignorance of Nature, man owes the creation of those illusive powers; under which he has so long trembled with fear; that superstitious worship, which has been the source of all his misery, and the evils entailed upon posterity.
For want of clearly comprehending his own peculiar nature, his proper course, his wants, and his rights, man has fallen in society, from FREEDOM into SLAVERY. He had forgotten the purpose of his existence, or else he believed himself obliged to suppress the natural desires of his heart, to sacrifice his welfare to the caprice of chiefs, either elected by himself, or submitted to without examination. He was ignorant of the true policy of association—of the object of government; he disdained to listen to the voice of Nature, which loudly proclaimed the price of all submission to be protection and happiness: the end of all government is the benefit of the governed, not the exclusive advantage of the governors. He gave himself up without enquiry to men like himself, whom his prejudices induced him to contemplate as beings of a superior order, as Gods upon earth, they profited by his ignorance, took advantage of his prejudices, corrupted him, rendered him vicious, enslaved him, and made him miserable. Thus man, intended by Nature for the full enjoyment of liberty, to patiently search out her laws, to investigate her secrets, to cling to his experience; has, from a neglect of her salutary admonitions, from an inexcusable ignorance of his own peculiar essence, fallen into servility: has been wickedly governed.
Having mistaken himself, he has remained ignorant of the indispensable affinity that subsists between him, and the beings of his own species: having mistaken his duty to himself, it consequently follows, he has mistaken his duty to others. He made a calculation in error of what his happiness required; he did not perceive, what he owed to himself, the excesses he ought to avoid, the desires he ought to resist, the impulses he ought to follow, in order to consolidate his felicity, to promote his comfort, and to further his advantage. In short, he was ignorant of his true interests; hence his irregularities, his excesses, his shameful extravagance, with that long train of vices, to which he has abandoned himself, at the expense of his preservation, at the hazard of his permanent prosperity.
It is, therefore, ignorance of himself that has hindered man from enlightening his morals. The corrupt authorities to which he had submitted, felt an interest in obstructing the practice of his duties, even when he knew them. Time, with the influence of ignorance, aided by his corruption, gave them a strength not to be resisted by his enfeebled voice. His duties continued unperformed, and he fell into contempt both with himself and with others.
The ignorance of Man has endured so long, he has taken such slow, such irresolute steps to ameliorate his condition, only because he has neglected to study Nature, to scrutinize her laws, to search out her expedients, to discover her properties, that his sluggishness finds its account, in permitting himself to be guided by example, rather than to follow experience, which demands activity; to be led by routine, rather than by his reason, which enjoins reflection; to take that for truth upon the authority of others, which would require a diligent and patient investigation. From hence may be traced the hatred man betrays for every thing that deviates from those rules to which he has been accustomed; hence his stupid, his scrupulous respect for antiquity, for the most silly, the most absurd and ridiculous institutions of his fathers: hence those fears that seize him, when the most beneficial changes are proposed to him, or the most likely attempts are made to better his condition. He dreads to examine, because he has been taught to hold it irreverent of something immediately connected with his welfare; his credulity suffers him to believe the interested advice, and spurns at those who wish to show him the danger of the road he is travelling.
