“The mental operation by which one achieves new concepts and which one denotes generally by the inadequate name of induction is not a simple but rather a very complicated process. Above all, it is not a logical process although such processes can be inserted as intermediary and auxiliary links. The principle effort that leads to the discovery of new knowledge is due to abstraction and imagination.”

—  Ernst Mach

“To me consensus seems to be—the process of abandoning all beliefs, principles, values and policies in search of something in which no-one believes, but to which no-one objects.”

Margaret Thatcher (1925–2013) British stateswoman and politician

Speech at Monash University (1981 Sir Robert Menzies Lecture) (6 October 1981) http://www.margaretthatcher.org/document/104712
First term as Prime Minister
Context: I count myself among those politicians who operate from conviction. For me, pragmatism is not enough. Nor is that fashionable word “consensus”. When I asked one of my Commonwealth colleagues at this Conference why he kept saying that there was a “consensus” on a certain matter, another replied in a flash “consensus is the word you use when you can't get agreement”! To me consensus seems to be—the process of abandoning all beliefs, principles, values and policies in search of something in which no-one believes, but to which no-one objects.—the process of avoiding the very issues that have to be solved, merely because you cannot get agreement on the way ahead. What great cause would have been fought and won under the banner “I stand for consensus”?

“The new education is a process and will not suffer from the applied imaginations of all who wish to be a part of it.”

Neil Postman (1931–2003) American writer and academic

[1] Will your questions increase the learner's will as well as capacity to learn? Will they help to give him a sense of joy in learning? Will they help to provide the learner with confidence in his ability to learn?
[2] In order to get answers, will the learner be required to make inquiries? (Ask further questions, clarify terms, make observations, classify data, etc?)
[3] Does each question allow for alternative answers (which implies alternative modes of inquiry)?
[4] Will the process of answering the questions tend to stress the uniqueness of the learner?
[6] Would the answers help the learner to sense and understand the universals in the human condition and so enhance his ability to draw closer to other people?
Teaching as a Subversive Activity (1969)
Context: These questions are not intended to represent a catechism for the new education. These are samples and illustrations of the kind of questions we think worth answering. Our set of questions is best regarded as a metaphor of our sense of relevance. If you took the trouble to list your own questions, it is quite possible that you prefer many or them to ours. Good enough. The new education is a process and will not suffer from the applied imaginations of all who wish to be a part of it. But in evaluating your own questions, as well as ours, bear in mind that there are certain standards that must be used. These standards must also be stated in the form of questions:

“A different conception of society, very different from that which now prevails, is in process of formation.”

Anarchism: Its Philosophy and Ideal (1896)
Context: A different conception of society, very different from that which now prevails, is in process of formation. Under the name of Anarchy, a new interpretation of the past and present life of society arises, giving at the same time a forecast as regards its future, both conceived in the same spirit as the above-mentioned interpretation in natural sciences. Anarchy, therefore, appears as a constituent part of the new philosophy, and that is why Anarchists come in contact, on so many points, with the greatest thinkers and poets of the present day.
In fact, it is certain that in proportion as the human mind frees itself from ideas inculcated by minorities of priests, military chiefs and judges, all striving to establish their domination, and of scientists paid to perpetuate it, a conception of society arises, in which conception there is no longer room for those dominating minorities. A society entering into possession of the social capital accumulated by the labor of preceding generations, organizing itself so as to make use of this capital in the interests of all, and constituting itself without reconstituting the power of the ruling minorities. It comprises in its midst an infinite variety of capacities, temperaments and individual energies: it excludes none. It even calls for struggles and contentions; because we know that periods of contests, so long as they were freely fought out, without the weight of constituted authority being thrown on the one side of the balance, were periods when human genius took its mightiest flight and achieved the greatest aims. Acknowledging, as a fact, the equal rights of all its members to the treasures accumulated in the past, it no longer recognizes a division between exploited and exploiters, governed and governors, dominated and dominators, and it seeks to establish a certain harmonious compatibility in its midst — not by subjecting all its members to an authority that is fictitiously supposed to represent society, not by trying to establish uniformity, but by urging all men to develop free initiative, free action, free association.
It seeks the most complete development of individuality combined with the highest development of voluntary association in all its aspects, in all possible degrees, for all imaginable aims; ever changing, ever modified associations which carry in themselves the elements of their durability and constantly assume new forms, which answer best to the multiple aspirations of all.
