John Harsanyi

“Rational behavior is behavior consistent with some well-defined objectives.”

“A game with incomplete information is a game where some players do not know the utility functions of some other players.”

“Utilitarianism is a moral philosophy which says that the right action is the one that maximizes aggregate utility.”

“The solution concept I proposed for games with incomplete information is now called Bayesian Nash equilibrium.”

“The main intellectual stimulus for my work on game theory came from my fascination with the logical and mathematical elegance of the von Neumann-Morgenstern theory.”

“Apart from moral considerations, dishonesty is a stupid policy.”

“People's behavior can be described as if they were maximizing their expected utility.”

“In a game of incomplete information, each player has a 'type,' which represents his private information.”

“Bayesian decision theory is a theory of rational behavior under uncertainty.”

“A society's moral code should be chosen from a position of impartiality.”
