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.
