“The word 'truth' itself ceases to have its old meaning. It describes no longer something to be found, with the individual conscience as the sole arbiter of whether in any particular instance the evidence (or the standing of those proclaiming it) warrants a belief; it becomes something to be laid down by authority, something which has to believed in the interest of unity of the organized effort and which may have to be altered as the exigencies of this organized effort require it.”

“The state should confine itself to establishing rules applying to general types of situations and should allow the individuals freedom in everything which depends on the circumstances of time and place, because only the individuals concerned in each instance can fully know these circumstances and adapt their actions to them. If the individuals are able to use their knowledge effectively in making plans, they must be able to predict actions of the state which may affect these plans. But if the actions of the state are to be predictable, they must be determined by rules fixed independently of the concrete circumstances which can be neither foreseen nor taken into account beforehand; and the particular effects of such actions will be unpredictable. If, on the other hand, the state were to direct the individual’s actions so as the achieve particular ends, its actions would have to be decided on the basis of the full circumstances of the moment and would therefore be unpredictable. Hence the familiar fact that the more the state “plans”, the more difficult planning becomes for the individual.”

“It is because every individual knows little and, in particular, because we rarely know which of us knows best that we trust the independent and competitive efforts of many to induce the emergence of what we shall want when we see it.”

“The case for individual freedom rests chiefly on the recognition of the inevitable and universal ignorance of all of us concerning a great many of the factors on which the achievement of our ends and welfare depend. It is because every individual knows so little and, in particular, because we rarely know which of us knows best that we trust the independent and competitive efforts of many to induce the emergence of what we shall want when we see it. Humiliating to human pride as it may be, we must recognize that the advance and even the preservation of civilization are dependent upon a maximum of opportunity for accidents to happen.”

“The argument for liberty is not an argument against organization, which is one of the most powerful tools human reason can employ, but an argument against all exclusive, privileged, monopolistic organization, against the use of coercion to prevent others from doing better.”

“Probably it is true enough that the great majority are rarely capable of thinking independently, that on most questions they accept views which they find ready-made, and that they will be equally content if born or coaxed into one set of beliefs or another. In any society freedom of thought will probably be of direct significance only for a small minority. But this does not mean that anyone is competent, or ought to have power, to select those to whom this freedom is to be reserved. It certainly does not justify the presumption of any group of people to claim the right to determine what people ought to think or believe.”

“Freedom to order our own conduct in the sphere where material circumstances force a choice upon us, and responsibility for the arrangement of our own life according to our own conscience, is the air in which alone moral sense grows and in which moral values are daily recreated in the free decision of the individual. Responsibility, not to a superior, but to one's own conscience, the awareness of a duty not exacted by compulsion, the necessity to decide which of the things one values are to be sacrificed to others, and to bear the consequences of one's own decision, are the very essence of any morals which deserve the name.”
