“This,” said a philosopher who had heard him with tokens of great impatience, “is the present condition of a wise man. The time is already come when none are wretched but by their own fault. Nothing is more idle than to inquire after happiness which Nature has kindly placed within our reach. The way to be happy is to live according to Nature, in obedience to that universal and unalterable law with which every heart is originally impressed; which is not written on it by precept, but engraven by destiny; not instilled by education, but infused at our nativity. He that lives according to Nature will suffer nothing from the delusions of hope or importunities of desire; he will receive and reject with equability of temper; and act or suffer as the reason of things shall alternately prescribe. Other men may amuse themselves with subtle definitions or intricate ratiocination. Let them learn to be wise by easier means: let them observe the hind of the forest and the linnet of the grove: let them consider the life of animals, whose motions are regulated by instinct; they obey their guide, and are happy. Let us therefore at length cease to dispute, and learn to live: throw away the encumbrance of precepts, which they who utter them with so much pride and pomp do not understand, and carry with us this simple and intelligible maxim: that deviation from Nature is deviation from happiness.” When he had spoken he looked round him with a placid air, and enjoyed the consciousness of his own beneficence. “Sir,” said the Prince with great modesty, “as I, like all the rest of mankind, am desirous of felicity, my closest attention has been fixed upon your discourse: I doubt not the truth of a position which a man so learned has so confidently advanced. Let me only know what it is to live according to Nature.” “When I find young men so humble and so docile,” said the philosopher, “I can deny them no information which my studies have enabled me to afford. To live according to Nature is to act always with due regard to the fitness arising from the relations and qualities of causes and effects; to concur with the great and unchangeable scheme of universal felicity; to co-operate with the general disposition and tendency of the present system of things.” The Prince soon found that this was one of the sages whom he should understand less as he heard him longer. He therefore bowed and was silent; and the philosopher, supposing him satisfied and the rest vanquished, rose up and departed with the air of a man that had co-operated with the present system.
