"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 by this means only that we are likely to see what virtue, science and authority can do, when animated by the noblest emulation, and working unanimously for the happiness of mankind."
