Hobbes’s own justification for the existence of governments relies on the assumption that, without a government, our lives in the state of nature would result in a state of war of every man against every man. Many contemporary scholars have tried to explain why universal war is unavoidable in Hobbes’s state of nature by utilizing modern game theory. However, most game-theoretic models that have been presented so far do not accurately capture what Hobbes deems to be the primary cause of (...) conflict in the state of nature – which is uncertainty, rather than people’s egoistic psychology. Any game- theoretic model that does not incorporate uncertainty into the picture is, therefore, I claim, the wrong model. In this paper, I use Bayesian game-theory to show how universal conflict can break-out in the state of nature - even when the majority of the population would strictly prefer to cooperate and seek peace with other people - due to uncertainty about the other person’s type. Along the way, I show that the valuation of one’s own life is one of the central mechanisms that drives Hobbes’s pessimistic conclusion. (shrink)

Thomas Hobbes’s concept of magnanimity, a descendant of Aristotle’s “greatness of soul,” plays a key role in Hobbes’s theory with respect to felicity and the virtue of justice. In his Critique du ‘De Mundo’, Hobbes implies that only genuinely magnanimous people can achieve the greatest felicity in their lives. A life of felicity is a life of pleasure, where the only pleasure that counts is the well grounded glory experienced by those who are magnanimous. Hobbes suggests that felicity involves the (...) successful pursuit of desires, a pursuit at which the magnanimous are particularly adept. Additionally, Hobbes implies that those who possess the virtue of justice must also possess magnanimity; it is the just person’s “Nobleness or Gallantnesse of courage, (rarely found).” Leo Strauss and Dorothea Krook suggest that this cannot be Hobbes’s “final word” on justice, because, they say, Hobbes considers magnanimity a type of pride, which he derogates and cannot consistently associate with virtue. I argue that magnanimity, associated with well-grounded glory, is not a type of pride; only vain glory is. (shrink)

Hobbes held distinctive views about the role of power in organizing and directing human life and posing the central problems of politics. His English vocabulary (unlike his Latin vocabulary) conflates conceptions of force, instrumental capacity, right and entitlement in a single term. It remains controversial how far he changed his conception of human nature over the last four decades of his intellectual life from a more to a less egoistic version, and how far, if he did, any such change modified (...) his recipe for pacifying human collective life. The best way of tracking the development of Hobbes?s political thinking is to trace the ways in which he saw the shifting contributions of power to human life in assisting, enabling or impeding human beings in living and acting as they wish.

According to Hobbes, individuals care about their relative standing in a way that shapes their social interactions. To model this aspect of Hobbesian psychology, this paper supposes that agents have social preferences, that is, preferences about their comparative resource holdings. Introducing uncertainty regarding the social preferences of others unleashes a process of trust-unravelling, ultimately leading to Hobbes’s ‘state of war’. This Trust-unravelling Model incorporates important features of Hobbes’s argument that past models ignore.
