Synopsis
A concise account of natural law deriving human and civic duties from sociability, arguing that morality and political obligation rest on reason and our need to live together.
Core passage idea
Paraphrase · Public domainBecause humans are weak and need one another, natural law commands us to cultivate sociability, and from this single duty the whole framework of moral and political obligation can be deduced.
It grounds rights and duties not in revelation or divine command alone but in the rational requirements of social life, a key move toward secular natural-law theory.
To avoid a bubble
Pair with Hobbes, Leviathan.
Reading note
Read it as a textbook of duties rather than a polemic; track how each obligation is justified by sociability and self-preservation.
