* Mr. Blair, doctor of divinity, and Mr. Black, doctor in chemistry, met at the coffee house in Edinburg: a new theological pamphlet written by doctor Priestly was thrown upon the table, "Really," said Dr. Blair, "this man had better confine himself to chemistry, for he is absolutely ignorant in theology:"--"I beg your pardon," answered Dr. Black, "he is in the right, he is a minister of the gospel, he ought to adhere to his profession, for in truth he knows nothing of chemistry."
You say, p. 15, "What is manifestly contrary to natural reason cannot be received by it;"--and p. 62, "With respect to intellect, men and brute animals are born in the same state, having the same external senses, which are the only inlets to all ideas, and consequently the source of all the knowledge and of all the mental habits they ever acquire."
Now if you admit, with Locke, and with us infidels, that every one has the right of rejecting whatever is contrary to his natural reason, and that all our ideas and all our knowledge are acquired only by the inlets of our external senses; What becomes of the system of revelation, and of that order of things in times past, which is so contradictory to that of the time present? unless we consider it as a dream of the human brain during the state of superstitious ignorance.
With these two single phrases, I could overturn the whole edifice of your faith. Dread not, however, sir, in me such overflowing zeal. For the same reason that I have not the frenzy of martyrdom, I have not that of making proselytes. It becomes those ardent, or rather acrimonious tempers, who mistake the violence of their sentiments for the enthusiasm of truth; the ambition of noise and rumor, for the love of glory; and for the love of their neighbor, the detestation of his opinions, and the secret desire of dominion.
As for me, who have not received from nature the turbulent qualities of an apostle, and never sustained in Europe the character of a dissenter, I am come to America neither to agitate the conscience of men, nor to form a sect, nor to establish a colony, in which, under the pretext of religion, I might erect a little empire to myself. I have never been seen evangelizing my ideas, either in temples or in public meetings. I have never likewise practiced that quackery of beneficence, by which a certain divine, imposing a tax upon the generosity of the public, procures for himself the honors of a more numerous audience, and the merit of distributing at his pleasure a bounty which costs him nothing, and for which he receives grateful thanks dexterously stolen from the original donors.
Either in the capacity of a stranger, or in that of a citizen, a sincere friend to peace, I carry into society neither the spirit of dissension, nor the desire of commotion; and because I respect in every one what I wish him to respect in me, the name of liberty is in my mind nothing else but the synonyma of justice.
As a man, whether from moderation or indolence, a spectator of the world rather than an actor in it, I am every day less tempted to take on me the management of the minds or bodies of men: it is sufficient for an individual to govern his own passions and caprices.
If by one of these caprices, I am induced to think it may be useful, sometimes, to publish my reflections, I do it without obstinacy or pretension to that implicit faith, the ridicule of which you desire to impart to me, p. 123. My whole book of the Ruins which you treat so ungratefully, since you thought it amusing, p. 122, evidently bears this character. By means of the contrasted opinions I have scattered through it, it breathes that spirit of doubt and uncertainty which appears to me the best suited to the weakness of the human mind, and the most adapted to its improvement, inasmuch as it always leaves a door open to new truths; while the spirit of dogmatism and immovable belief, limiting our progress to a first received opinion, binds us at hazard, and without resource, to the yoke of error or falsehood, and occasions the most serious mischiefs to society; since by combining with the passions, it engenders fanaticism, which, sometimes misled and sometimes misleading, though always intolerant and despotic, attacks whatever is not of its own nature; drawing upon itself persecution when it is weak, and practising persecution when it is powerful; establishing a religion of terror, which annihilates the faculties, and vitiates the conscience: so that, whether under a political or a religious aspect, the spirit of doubt is friendly to all ideas of liberty, truth, or genius, while a spirit of confidence is connected with the ideas of tyranny, servility, and ignorance.
If, as is the fact, our own experience and that of others daily teaches us that what at one time appeared true, afterwards appeared demonstrably false, how can we connect with our judgments that blind and presumptuous confidence which pursues those of others with so much hatred?
No doubt it is reasonable, and even honest, to act according to our present feelings and conviction: but if these feelings and their causes do vary by the very nature of things, how dare we impose upon ourselves or others an invariable conviction? How, above all, dare we require this conviction in cases where there is really no sensation, as happens in purely speculative questions, in which no palpable fact can be presented?
Therefore, when opening the book of nature, (a more authentic one and more easy to be read than leaves of paper blackened over with Greek or Hebrew,) and when I reflected that the slightest change in the material world has not been in times past, nor is at present effected by the difference of so many religions and sects which have appeared and still exist on the globe, and that the course of the seasons, the path of the sun, the return of rain and drought, are the same for the inhabitants of each country, whether Christians, Mussulmans, Idolaters, Catholics, Protestants, etc., I am induced to believe that the universe is governed by laws of wisdom and justice, very different from those which human ignorance and intolerance would enact.
And as in living with men of very opposite religious persuasions, I have had occasion to remark that their manners were, nevertheless, very analogous; that is to say, among the different Christian sects, among the Mahometans, and even among those people who were of no sect, I have found men who practise all the virtues, public and private, and that too without affectation; while others, who were incessantly declaiming of God and religion, abandoned themselves to every vicious habit which their belief condemned, I thereby became convinced that Ethics, the doctrines of morality, are the only essential, as they are only demonstrable, part of religion. And as, by your own avowal, the only end of religion is to render men better, in order to add to their happiness, p. 62, I have concluded that there are but two great systems of religion in the world, that of good sense and beneficence, and that of malice and hypocrisy.
In closing this letter, I find myself embarrassed by the nature of the sentiment which I ought to express to you, for in declaring as you have done, p. 123, that you do not care for the contempt of such as me* (ignorant as you were of my opinion), you tell me plainly that you do not care for their esteem. I leave, therefore, to your discernment and taste to determine the sentiment most congenial to my situation and your desert.
