Society is indeed a contract. It is a partnership in all science; a partnership in all art; a partnership in every virtue, and in all perfection. As the ends of such a partnership cannot be obtained in many generations, it becomes a partnership not only between those who are living, but between those who are living, those who are dead, and those who are to be born.

Unsociable humors are contracted in solitude, which will, in the end, not fail of corrupting the understanding as well as the manners, and of utterly disqualifying a man for the satisfactions and duties of life.
