"Definitions, like questions and metaphors, are instruments for thinking. Their authority rests entirely on their usefulness, not their correctness. We use definitions in order to delineate problems we wish to investigate, or to further interests we wish to promote. In other words, we invent definitions and discard them as suits our purposes. And yet, one gets the impression that... God has provided us with definitions from which we depart at the risk of losing our immortal souls. This is the belief that I have elsewhere called "definition tyranny," which may be defined... as the process of accepting without criticism someone else's definition of a word or a problem or a situation. I can think of no better method of freeing students from this obstruction of the mind than to provide them with alternative definitions of every concept and term with which they must deal in a subject. Whether it be "molecule," "fact," "law," "art," "wealth," "gene," or whatever, it is essential that students understand that definitions are hypotheses, and that embedded in them is a particular philosophical, sociological, or epistemological point of view."

“In order to understand what kind of behaviors classrooms promote, one must become accustomed to observing what, in fact, students actually do in them. What students do in a classroom is what they learn , and what they learn to do is the classroom's message . Now, what is it that students do in the classroom? Well, mostly they sit and listen to the teacher. Mostly, they are required to believe in authorities, or at least pretend to such belief when they take tests. Mostly they are required to remember. They are almost never required to make observations, formulate definitions, or perform any intellectual operations that go beyond repeating what someone else says is true. They are rarely encouraged to ask substantive questions, although they are permitted to ask about administrative and technical details. It is practically unheard of for students to play any role in determining what problems are worth studying or what procedures of inquiry ought to be used. Examine the types of questions teachers ask in classrooms, and you will find that most of them are what might technically be called "convergent questions," but what might more simply be called "Guess what I am thinking " questions.”

“Because of what computers commonly do... With the exception of the electric light, there never has been a technology that better exemplifies Marshall McLuhan's aphorism "The medium is the message." …the "message" of computer technology is comprehensive and domineering. The computer argues, to put it baldly, that the most serious problems confronting us at both personal and professional levels require technical solutions through fast access to information otherwise unavailable. ...this is... nonsense. Our most serious problems are not technical, nor do they arise from inadequate information. If a nuclear catastrophe occurs, it shall not be because of inadequate information. Where people are dying of starvation, it does not occur because of inadequate information. If families break up, children are mistreated, crime terrorizes a city, education is impotent, it does not happen because of inadequate information. Mathematical equations, instantaneous communication, and vast quantities of information have nothing whatever to do with any of these problems. And the computer is useless in addressing them.”

“Scientific language, which Korzybski used as his model of sane language, is almost exclusively extensional and denotative, or at least tries to be. The language of the mentally ill, most obviously "un-sane," is almost totally intensional and connotative. This is the language that does not correspond to anything "out there," and this is, in fact, how and perhaps even why the user is mentally ill. Korzybski's concern with keeping the conscious "connection" or correspondence between language and verifiable referents is, for all practical purposes, paralleled by the process of psychotherapy. In this process, which is largely "just talk," the purpose is to foster closer and more accurate correspondence between the patient's language and externally verifiable meanings. As a semanticist would say, the process of psychotherapy is aimed at shifting the patient's word choices from those having a highly intensional, connotative meanings to others carrying more denotative meanings. A person suffering from paranoid schizophrenia might use perfectly "correct" English in an unassailably "logical" way, but the problem with his language is that it does not correspond to anything "out there.”

“The key to all fanatical beliefs is that they are self-confirming.... fanatical not because they are "false", but because they are expressed in such a way that they can never be shown to be false.”

“In the development of intelligence nothing can be more "basic" than learning how to ask productive questions. Many years ago, in Teaching as a Subversive Activity, Charles Weingartner and I expressed our astonishment at the neglect shown in school toward this language art. ...The "back to the basics" philosophers rarely mention it, and practicing teachers usually do not find room for it in their curriculums. …all our knowledge results from questions, which is another way of saying that question-asking is our most important intellectual tool… There are at present no reading tests anywhere that measure the ability of students to address probing questions to the particular texts they are reading... What students need to know are the rules of discourse which comprise the subject, and among the most central of such rules are those which govern what is and what is not a legitimate question.”
