"You're a bitter man," said Candide. "That's because I've lived," said Martin.

Being of opinion that the doctrine and history of so extraordinary a sect as the Quakers were very well deserving the curiosity of every thinking man, I resolved to make myself acquainted with them, and for that purpose made a visit to one of the most eminent of that sect in England, who, after having been in trade for thirty years, had the wisdom to prescribe limits to his fortune, and to his desires, and withdrew to a small but pleasant retirement in the country, not many miles from London. Here it was that I made him my visit. His house was small, but neatly built, and with no other ornaments but those of decency and convenience.

He advanced toward me without moving his hat, or making the least inclination of his body; but there appeared more real politeness in the open, humane air of his countenance, than in drawing one leg behind the other, and carrying that in the hand which is made to be worn on the head. "Friend," said he, "I perceive thou art a stranger, if I can do thee any service thou hast only to let me know it." "Sir," I replied, bowing my body, and sliding one leg toward him, as is the custom with us, "I flatter myself that my curiosity, which you will allow to be just, will not give you any offence, and that you will do me the honor to inform me of the particulars of your religion." "The people of thy country," answered the Quaker, "are too full of their bows and their compliments; but I never yet met with one of them who had so much curiosity as thyself. Come in and let us dine first together."

I opened with that which good Catholics have more than once made to Huguenots. "My dear sir," said I, "were you ever baptized?" "No, friend," replied the Quaker, "nor any of my brethren." "Zounds!" said I to him, "you are not Christians then!" "Friend," replied the old man, in a soft tone of voice, "do not swear; we are Christians, but we do not think that sprinkling a few drops of water on a child's head makes him a Christian." "My God!" exclaimed I, shocked at his impiety, "have you then forgotten that Christ was baptized by St. John?" "Friend," replied the mild Quaker, "once again, do not swear. Christ was baptized by John, but He Himself never baptized any one; now we profess ourselves disciples of Christ, and not of John." "Mercy on us," cried I, "what a fine subject you would be for the holy inquisitor! In the name of God, my good old man, let me baptize you."

O Truth! pure and sacred virgin, when wilt thou be worthily revered? O Goddess who instructs us, why didst thou put thy palace in a well? When will our learned writers, alike free from bitterness and from flattery, faithfully teach us life?
