“As conceived in this book, economics is the science of rational choice in a world─our world─in which resources are limited in relation to human wants. The task of economics, so defined, is to explore the implications of assuming that man is a rational maximizer of his ends in life, his satisfactions─what we shall call his “self-interest.” Rational maximization should not be confused with conscious calculation. Economics is not a thoery about consciousness. Behavior is rational when it conforms to the model of rational choice, whatever the state of mind of the chooser.(…) Nor is perfect rationality assumed; rational-choice thoery allows us to assume that rationality is “bounded” because of human cognitive limitations, although another way to think of those limitations is as costs of absorbing and using information.”

“The first consequence of the principle of bounded rationality is that the intended rationality of an actor requires him to construct a simplified model of the real situation in order to deal with it. He behaves rationally with respect to this model, and such behavior is not even approximately optimal with respect to the real world. To predict his behavior we must understand the way in which this simplified model is constructed, and its construction will certainly be related to his psychological properties as a perceiving, thinking, and learning animal.”

“Mike Flynn is a fine person, and I asked for his resignation. He respectfully gave it. He is a man who there was a certain amount of information given to Vice President Pence, who is with us today. And I was not happy with the way that information was given. He didn't have to do that, because what he did wasn't wrong. What he did in terms of the information he saw. What was wrong was the way that other people, including yourselves in this room, were given that information, because that was classified information that was given illegally. That's the real problem.”

“It is impossible for the behavior of a single, isolated individual to reach a high degree of rationality. The number of alternatives he must explore is so great, the information he would need to evaluate them so vast that even an approximation to objective rationality is hard to conceive. Individual choice takes place in rationality is hard to conceive… Actual behavior falls short in at least three ways, of objective rationality:”

“Broadly stated, the task is to replace the global rationality of economic man with a kind of rational behavior that is compatible with the access to information and the computational capacities that are actually possessed by organisms, including man, in the kinds of environments in which such organisms exist.”

“An individual's self-concept is the core of his personality. It affects every aspect of human behavior: the ability to learn, the capacity to grow and change. A strong, positive self-image is the best possible preparation for success in life.”

“As a "rational" being, he now places his behavior under the control of abstractions. He will no longer tolerate being carried away by sudden impressions, by intuitions.”

Friedrich Nietzsche (1844–1900) German philosopher, poet, composer, cultural critic, and classical philologist

On Truth and Lie in an Extra-Moral Sense (1873)
Context: The venerability, reliability, and utility of truth is something which a person demonstrates for himself from the contrast with the liar, whom no one trusts and everyone excludes. As a "rational" being, he now places his behavior under the control of abstractions. He will no longer tolerate being carried away by sudden impressions, by intuitions.

“The term rationalize refers to any situations in which a person's action is described with reference to some supporting reason or cause. The term “legitimate” refers to one criterion by which rationalizations are selected from the many possible explanations for action. Justifications or rationalizations are selected primarily when they are acceptable explanations in a given social context. This means they fit with the facts as known according to the rules of behavior generally followed.”

Gerald R. Salancik (1943–1996) American organizational theorist
