There lived at Babylon, in the reign of King Moabdar, a young man named Zadig, of a good natural disposition, strengthened and improved by education. Though rich and young, he had learned to moderate his passions; he had nothing stiff or affected in his behavior, he did not pretend to examine every action by the strict rules of reason, but was always ready to make proper allowances for the weakness of mankind. It was matter of surprise that, notwithstanding his sprightly wit, he never exposed by his raillery those vague, incoherent, and noisy discourses, those rash censures, ignorant decisions, coarse jests, and all that empty jingle of words which at Babylon went by the name of conversation. He had learned, in the first book of Zoroaster, that self love is a football swelled with wind, from which, when pierced, the most terrible tempests issue forth. Above all, Zadig never boasted of his conquests among the women, nor affected to entertain a contemptible opinion of the fair sex. He was generous, and was never afraid of obliging the ungrateful; remembering the grand precept of Zoroaster, "When thou eatest, give to the dogs, should they even bite thee." He was as wise as it is possible for man to be, for he sought to live with the wise. Instructed in the sciences of the ancient Chaldeans, he understood the principles of natural philosophy, such as they were then supposed to be; and knew as much of metaphysics as hath ever been known in any age, that is, little or nothing at all. He was firmly persuaded, notwithstanding the new philosophy of the times, that the year consisted of three hundred and sixty-five days and six hours, and that the sun was in the center of the world. But when the principal magi told him, with a haughty and contemptuous air, that his sentiments were of a dangerous tendency, and that it was to be an enemy to the state to believe that the sun revolved round its own axis, and that the year had twelve months, he held his tongue with great modesty and meekness. Possessed as he was of great riches, and consequently of many friends, blessed with a good constitution, a handsome figure, a mind just and moderate, and a heart noble and sincere, he fondly imagined that he might easily be happy. He was going to be married to Semira, who, in point of beauty, birth, and fortune, was the first match in Babylon. He had a real and virtuous affection for this lady, and she loved him with the most passionate fondness.
