But if the progress of the arts and sciences has added nothing to our real happiness; if it has corrupted our morals, and if that corruption has vitiated our taste, what are we to think of the herd of text-book authors, who have removed those impediments which nature purposely laid in the way to the Temple of the Muses, in order to guard its approach and try the powers of those who might be tempted to seek knowledge? What are we to think of those compilers who have indiscreetly broken open the door of the sciences, and introduced into their sanctuary a populace unworthy to approach it, when it was greatly to be wished that all who should be found incapable of making a considerable progress in the career of learning should have been repulsed at the entrance, and thereby cast upon those arts which are useful to society. A man who will be all his life a bad versifier, or a third-rate geometrician, might have made nevertheless an excellent clothier. Those whom nature intended for her disciples have not needed masters. Bacon, Descartes and Newton, those teachers of mankind, had themselves no teachers. What guide indeed could have taken them so far as their sublime genius directed them? Ordinary masters would only have cramped their intelligence, by confining it within the narrow limits of their own capacity. It was from the obstacles they met with at first, that they learned to exert themselves, and bestirred themselves to traverse the vast field which they covered. If it be proper to allow some men to apply themselves to the study of the arts and sciences, it is only those who feel themselves able to walk alone in their footsteps and to outstrip them. It belongs only to these few to raise monuments to the glory of the human understanding. But if we are desirous that nothing should be above their genius, nothing should be beyond their hopes. This is the only encouragement they require. The soul insensibly adapts itself to the objects on which it is employed, and thus it is that great occasions produce great men. The greatest orator in the world was Consul of Rome, and perhaps the greatest of philosophers Lord Chancellor of England. Can it be conceived that, if the former had only been a professor at some University, and the latter a pensioner of some Academy, their works would not have suffered from their situation. Let not princes disdain to admit into their councils those who are most capable of giving them good advice. Let them renounce the old prejudice, which was invented by the pride of the great, that the art of governing mankind is more difficult than that of instructing them; as if it was easier to induce men to do good voluntarily, than to compel them to it by force. Let the learned of the first rank find an honourable refuge in their courts; let them there enjoy the only recompense worthy of them, that of promoting by their influence the happiness of the peoples they have enlightened by their wisdom. It is
