A motivation behind social contract theory is that in many contexts, it is rational for individuals to act in accordance with their own self-interest at the expense of others. However, we are all better off as individuals if we cooperate. A. True
B. False

True

Explanation:

Thomas Hobbes (1588–1679), John Locke (1632–1704), and Jean-Jacques Rousseau (1712–78) were the classic social-contract theorists that examined why societies established the authority of a state to which people must obey. According to this Western political philosophy, although following our own self-interest at the expense of others is rational, we establish societies in which we oblige to certain rules because cooperation brings benefits that would be unachievable without the help of others.
