say, truth can never be worthy of ridicule, but still it may be ridiculed. Just ridicule is a sufficient test of truth; but after all we should be driven to an inquiry, upon the principles of reasoning, whether the ridicule were just or not. Boldness, which is not incompatible with decency and candour, I do hold to be an absolute requisite in all speech and argument, where truth is the object of inquiry. Therefore when I am asked, whether there is a God or no God, I do not mince the matter, but I boldly answer there is none, and give my reason for my disbelief; for I adopt my friend's answer by the publication of it.

That mischief may ensue to society by such freedom of discussion is also another argument for me to consider; I do not say to combat, for though I were convinced or could not resist the argument that mischief would ensue to society by such a discussion, yet I should think myself intitled to enter into it. I have a right to truth, and to publish truth, let society suffer or not suffer by it. That society which suffers by truth should be otherwise constituted; and as I cannot well think that truth will hurt any society rightly constituted, so I should rather be inclined to doubt the force of the argument in case atheism being found to be truth should apparently be proved prejudicial to such a society.

I come unprejudiced to the question, and when I have promised you an answer to your future Letters in support of revelation, I have neither anticipated your argument nor prejudged the cause. I hold myself open to be convinced, and if I am convinced I shall say so, which is equally answering as if I denied the force of your observations. In that sense only I promise an answer. If I believe I shall say, I do; but I shall not believe and tremble, confident as I am, that if I act an honest part in life, whether there be a Deity and a future existence or not, whatever reason I may have to rejoice in case such ideas he realised, I can upon such an issue have none to tremble. I look upon myself to have more reason to be temporally afraid than eternally so. Dr. Priestley or any other Doctor can put his name boldly to a book in favour of Theism, loudly call the supporters of a contrary doctrine to the argument, and if no answer is produced, assert their own reasoning to be unanswerable. In that sense their sort of reasoning has been frequently unanswerable. Here however is an instance of a poor unknown individual, making experience of the candour of the ecclesiastics and the equity of the laws of England, for he ventures to subscribe his publication with his name as well as Dr. Priestley does his Letters, to which this publication is an answer. Perhaps he may have cause to repent of his hardiness, but if he has, he is equally resolved to glory in his martyrdom, as to suffer it. Whatever advantage religion has had in the enumeration of it's martyrs, the cause of atheism may boast the same. As to the instances of the professors of any particular form of religion, or modification of that form, such as Christians or sects of Christians, suffering martyrdom for their belief, I shall no more allow them to be martyrs for theism than Pagans similarly suffering for their belief, shall I call martyrs for atheism. Theism very likely has had it's martyrs. I can instance one I think in Socrates, and I shall mention Vanini as a martyr for atheism. The conduct of those two great men in their last moments may be worth attending to. The variety of other poor heretical wretches, who have been immolated at the shrine of absurdity for all the possible errors of human credence, let them have their legendary fame. I put them out of the scale in this important inquiry.

Not that I really think the argument to be much advanced by naming the great supporters of one opinion or of another. In mathematics, mechanics, natural philosophy, in literature, taste, and politics the sentiments of great men of great genius are certainly of weight. There are some subjects capable of demonstration, many indeed which the ingenuity of one man can go farther to illustrate than that of another. The force of high authority is greater in the three former sciences than in the latter. Theism and Atheism I hold to be neither of them strictly demonstrable. You, Dr. Priestley, agree with me in that. Still I hold the question capable of being illustrated by argument, and I should hold the authority of great men's names to be of more weight in this subject, were I not necessarily forced to consider that all education is strongly calculated to support the idea of a Deity; by this education prejudice is introduced, and prejudice is nothing else than a corruption of the understanding. Certain principles, call them, if you please, data, must be agreed upon before any reasoning can take place. Disputants must at least agree in the ideas which they annex to the language they use. But when prejudice has made a stand, argumentation is set at so wide a distance, through a want of fixt data to proceed upon, that attention is in vain applied to the dispute. Besides, the nature of the subject upon which this prejudice takes place, is such, that the finest genius is nearly equally liable to an undue bias with the most vulgar. To question with boldness and indifference, whether an individual, all-forming, all-seeing and all-governing Being exists, to whom, if he exists, we may possibly be responsible for our actions, whose intelligence and power must be infinitely superior to our own, requires a great conquest of former habitude, a firmness of nerves, as well as of understanding; it will therefore be no great wonder, if such men as Locke and Newton can be named among the believers in a Deity. They were christians as well as theists, so that their authority goes as far in one respect as in the other. But if the opinions of men of great genius are to have weight, what is to be said of modern men of genius? You, Sir, are of opinion that the world is getting wiser as well as better. There is all the reason in the world it should get wiser at least, since wisdom is only a collection of experience, and there must be more experience as the world is older. Modern Philosophers are nearly all atheists. I take the term atheist here in the popular sense. Hume, Helvetius, Diderot, D'Alembert. Can they not weigh against Locke and Newton, and even more than Locke and Newton, since their store of knowledge and learning was at hand to be added to their own, and among them are those who singly possessed equal science in mathematics as in metaphysics? It is not impossible, perhaps not improbable, from his course of learning and inquiries, that if Dr. Priestley had not from his first initiation into science been dedicated for what is called the immediate service of God, he himself might have been one of the greatest disprovers of his pretended divinity.

In England you think, Sir, that atheism is not prevalent among men of free reasoning, though you acknowledge it to be much so in other countries. It is not the first time it has been observed that the greater the superstition of the common people the less is that of men of letters. In the heart of the Papal territories perhaps is the greatest number of atheists, and in the reformed countries the greatest number of deists. Yet it is a common observation, especially by divines, that deism leads to atheism, and I believe the observation is well founded. I hardly need explain here, that by deism in this sense is meant a belief in the existence of a Deity from natural and philosophical principles, and a disbelief in all immediate revelation by the Deity of his own existence. Such is the force of habit, that it is by degrees only, that even men of sense and firmness shake off one prejudice after another. They begin by getting rid of the absurdities of all popular religions. This leaves them simple deists, but the force of reasoning next carries them a step farther, and whoever trusts to this reasoning, devoid of all fear and prejudice, is very likely to end at last in being an atheist. Nor do I
