“The theory of rational action may therefore fail, because it is unable to produce unique prescriptions and predictions. It may also fail if the agents’ behavior does not conform to predictions, whether these are unique or not; that is, if the agents are irrational. There are multiple sources of irrationality, hot or cold.”

“Data is discrimination between physical states of things (black, white, etc.) that may convey or not convey information to an agent. Whether it does so or not depends on the agent's prior stock of knowledge.”

“The tendency to be rational is the consistent and hence predictable element in human behavior.”

“There may be occasions when it is best to behave irrationally, but whether there are should be decided rationally.”

“Skepticism is the agent of reason against organized irrationalism--and is therefore one of the keys to human social and civic decency.”

“Promises are the uniquely human way of ordering the future, making it predictable and reliable to the extent that this is humanly possible.”

“The devil’s agents may be of flesh and blood, may they not?”

“One area which shows how unknowingly predictable we are, is the way we decorate our houses. We all feel we make unique and distinct choices, yet we all conform to a cultural standard.”

“Political theorists often fail to appreciate that arguments about how politics ought to be organized typically depend on relational claims involving agents, actions, legitimacy, and ends.”

“In stochastic processes the future is not uniquely determined, but we have at least probability relations enabling us to make predictions.”
