B: What is natural law?

A: The instinct which makes us feel justice.

B: What do you call just and unjust?

A: What appears such to the entire universe.

B: The universe is composed of many heads. It is said that in Lacedæmon were applauded thefts for which people in Athens were condemned to the mines.

A: Abuse of words, logomachy, equivocation; theft could not be committed at Sparta, when everything was common property. What you call "theft" was the punishment for avarice.

B: It was forbidden to marry one's sister in Rome. It was allowed among the Egyptians, the Athenians and even among the Jews, to marry one's sister on the father's side. It is but with regret that I cite that wretched little Jewish people, who should assuredly not serve as a rule for anyone, and who (putting religion aside) was never anything but a race of ignorant and fanatic brigands. But still, according to their books, the young Thamar, before being ravished by her brother Amnon, says to him:—"Nay, my brother, do not thou this folly, but speak unto the king; for he will not withhold me from thee." (2 Samuel xiii. 12, 13.)

A: Conventional law all that, arbitrary customs, fashions that pass: the essential remains always. Show me a country where it was honourable to rob me of the fruit of my toil, to break one's promise, to lie in order to hurt, to calumniate, to assassinate, to poison, to be ungrateful towards a benefactor, to beat one's father and one's mother when they offer you food.

B: Have you forgotten that Jean-Jacques, one of the fathers of the modern Church, has said that "the first man who dared enclose and cultivate a piece of land" was the enemy "of the human race," that he should have been exterminated, and that "the fruits of the earth are for all, and that the land belongs to none"? Have we not already examined together this lovely proposition which is so useful to society (Discourse on Inequality, second part)?

A: Who is this Jean-Jacques? he is certainly not either John the Baptist, nor John the Evangelist, nor James the Greater, nor James the Less[19]; it must be some Hunnish wit who wrote that abominable impertinence or some poor joker bufo magro who wanted to laugh at what the entire world regards as most serious. For instead of going to spoil the land of a wise and industrious neighbour, he had only to imitate him; and every father of a family having followed this example, behold soon a very pretty village formed. The author of this passage seems to me a very unsociable animal.
