Women watched for the spectacular performances of the men, and there can be no reasonable doubt that the presence of an audience is a very important factor in shaping the men's behavior. In fact, it is probable that the men are more exhibitionistic because the women admire their performances. Conversely, there can be no doubt that the spectacular behavior is a stimulus which summons the audience together, promoting in the women the appropriate behavior.

Numbers are the product of counting. Quantities are the product of measurement. This means that numbers can conceivably be accurate because there is a discontinuity between each integer and the next. Between two and three there is a jump. In the case of quantity there is no such jump, and because jump is missing in the world of quantity it is impossible for any quantity to be exact. You can have exactly three tomatoes. You can never have exactly three gallons of water. Always quantity is approximate.

Schizophrenia--its nature, etiology, and the kind of therapy to use for it--remains one of the most puzzling of the mental illnesses. The theory of schizophrenia presented here is based on communications analysis, and specifically on the Theory of Logical Types. From this theory and from observations of schizophrenic patients is derived a description, and the necessary conditions for, a situation called the "double bind"--a situation in which no matter what a person does, he "can't win." It is hypothesized that a person caught in the double bind may develop schizophrenic symptoms.

Earlier fundamental work of Whitehead, Russell, Wittgenstein, Carnap, Whorf, etc., as well as my own attempt to use this earlier thinking as an epistemological base for psychiatric theory, led to a series of generalizations: That human verbal communication can operate and always does operate at many contrasting levels of abstraction. These range in two directions from the seemingly simple denotative level (“The cat is on the mat”). One range or set of these more abstract levels includes those explicit or implicit messages where the subject of discourse is the language. We will call these metalinguistic (for example, “The verbal sound ‘cat’ stands for any member of such and such class of objects”, or “The word, ‘cat’ has no fur and cannot scratch”). The other set of levels of abstraction we will call metacommunicative (e.g., “My telling you where to find the cat was friendly”, or “This is play”). In these, the subject of discourse is the relationship between the speakers. It will be noted that the vast majority of both metalinguistic and metacommunicative messages remain implicit; and also that, especially in the psychiatric interview, there occurs a further class of implicit messages about how metacommunicative messages of friendship and hostility are to be interpreted.

If it were possible adequately to present the whole of a culture, stressing every aspect exactly as appears in the culture itself, no single detail would appear bizarre or strange or arbitrary to the reader, but rather the details would all appear natural and reasonable as they do to the natives who have lived all their lives within the culture.

Whenever we pride ourselves upon finding a newer, stricter way of thought or exposition; whenever we start insisting too hard upon "operationalism" or symbolic logic or any other of these very essential systems of tramlines, we lose something of the ability to think new thoughts. And equally, of course, whenever we rebel against the sterile rigidity of formal thought and exposition and let our ideas run wild, we likewise lose. As I see it, the advances in scientific thought come from a combination of loose and strict thinking, and this combination is the most precious tool of science.
