“For action to be rational, the beliefs on which it is based must themselves be well founded. In turn, this requirement is divided into two parts. On the one hand, the beliefs must be unbiased with respect to the information the agent possesses; on the other hand, he must gather an optimal amount of information.”

“[Task uncertainty is] the difference between the amount of information required to perform the task and the amount of information already possessed by the organisation.”

Jay R. Galbraith (1939–2014) American business theorist

“Having gestured at the concept of rationality, I ought to stress that I intend nothing very grand or precise by that much abused term. When I speak of agents as having rational beliefs, I mean only that their beliefs (what they hold to be true) should be suitable beliefs for them to hold true in the circumstances in which they find themselves. A rational belief will thus be one that an agent has attained by some accredited process of reasoning.”

Quentin Skinner (1940) British historian

“A man must be himself convinced if he is to convince others. The prophet must be his own disciple, or he will make none. Enthusiasm is contagious: belief creates belief.”

George Henry Lewes (1817–1878) British philosopher

The Principles of Success in Literature (1865)
Context: A man must be himself convinced if he is to convince others. The prophet must be his own disciple, or he will make none. Enthusiasm is contagious: belief creates belief. There is no influence issuing from unbelief or from languid acquiescence. This is peculiarly noticeable in Art, because Art depends on sympathy for its influence, and unless the artist has felt the emotions he depicts we remain unmoved: in proportion to the depth of his feeling is our sympathetic response; in proportion to the shallowness or falsehood of his presentation is our coldness or indifference.

“[ Lawyers are clear. On the one hand, they are important and deserve] special consideration [because they] are always found at the right hand of the administrator whose actions must be legally defensible. A lawyer, therefore, sits close to the seat of administrative authority… Policy may have to yield to constitutionality, and the lawyers prescribe. On the other hand, it must be said that the training of the lawyer, based on precedent, and looking backward rather than forward for guidance, is not a training which is suited to make an ideal administrator.”

“The king said that mankind must not work for themselves. The priest said that mankind must not think for themselves. One forged chains for the hands, the other for the soul.”

Robert G. Ingersoll (1833–1899) Union United States Army officer

The Liberty of Man, Woman and Child (1877)
Context: Nothing has been left undone by the enemies of freedom. Every art and artifice, every cruelty and outrage has been practiced and perpetrated to destroy the rights of man. In this great struggle every crime has been rewarded and every virtue has been punished. Reading, writing, thinking and investigating have all been crimes.
Every science has been an outcast.
All the altars and all the thrones united to arrest the forward march of the human race. The king said that mankind must not work for themselves. The priest said that mankind must not think for themselves. One forged chains for the hands, the other for the soul.

“On the other hand, you can chose to be an insider, to play the game… if you chose to be an insider you'll be given information that outsiders don't have, you'll be given… an opportunity… to make some… small tiny changes within the inside, but the one rule that you must respect, is that insiders do not tell outsiders the truth, and they do not turn against other insiders…”

“Information wants to be free. (Excerpted from: "On the one hand information wants to be expensive, because it's so valuable. The right information in the right place just changes your life. On the other hand, information wants to be free, because the cost of getting it out is getting lower and lower all the time. So you have these two fighting against each other."”

Stewart Brand (1938) American writer

Whole Earth Review, May 1985, p. 49.

“This is your country as well as anybody else's country. This country is founded upon the principle of equality. He that is meritorious and virtuous, intellectual and well informed, must stand highest, without regard to color.”

“A group may have more group information or less group information than its members. A group of non-social animals, temporarily assembled, contains very little group information, even though its members may possess much information as individuals. This is because very little that one member does is noticed by the others and is acted on by them in a way that goes further in the group. On the other hand, the human organism contains vastly more information, in all probability, than does any one of its cells. There is thus no necessary relation in either direction between the amount of racial or tribal or community information and the amount of information available to the individual.”

“No man holding a strong belief on one side of a question, or even wishing to hold a belief on one side, can investigate it with such fairness and completeness as if he were really in doubt and unbiased; so that the existence of a belief not founded on fair inquiry unfits a man for the performance of this necessary duty.”

William Kingdon Clifford (1845–1879) English mathematician and philosopher

The Ethics of Belief (1877), The Duty of Inquiry
Context: No man holding a strong belief on one side of a question, or even wishing to hold a belief on one side, can investigate it with such fairness and completeness as if he were really in doubt and unbiased; so that the existence of a belief not founded on fair inquiry unfits a man for the performance of this necessary duty.
Nor is it that truly a belief at all which has not some influence upon the actions of him who holds it. He who truly believes that which prompts him to an action has looked upon the action to lust after it, he has committed it already in his heart. If a belief is not realized immediately in open deeds, it is stored up for the guidance of the future. It goes to make a part of that aggregate of beliefs which is the link between sensation and action at every moment of all our lives, and which is so organized and compacted together that no part of it can be isolated from the rest, but every new addition modifies the structure of the whole. No real belief, however trifling and fragmentary it may seem, is ever truly insignificant; it prepares us to receive more of its like, confirms those which resembled it before, and weakens others; and so gradually it lays a stealthy train in our inmost thoughts, which may someday explode into overt action, and leave its stamp upon our character for ever.
