If men did not unite, if they avoided and fled from each other, it would be necessary to ask the reason, and to inquire why they kept apart; but we are all born with relations; a son comes into the world beside his father, and stays there: that is society, and the cause of society.

Context

“Paris, the 9th of the moon of Chahban, 1715. Letter 95 Usbek to Rhedi, at Venice I HAVE never heard public law discussed, without a preliminary careful inquiry into the origin of society, which seems to me absurd. If men did not unite, if they avoided and fled from each other, it would be necessary to ask the reason, and to inquire why they kept apart; but we are all born with relations; a son comes into the world beside his father, and stays there: that is society, and the cause of society. International law is better understood in Europe than in Asia; and yet it must be said that the passions of princes, the patience of the people, and the flattery of authors, have corrupted all its principles.” source
