“There are different levels of organization in the occurrence of events. You cannot explain the events of one level in terms of the events of another. For example, you cannot explain life in terms of mechanical concepts, nor society in terms of individual psychology. Analysis can only take you down the scale of organization. It cannot reveal the workings of things on a higher level. To some extent the holistic philosophers are right.”

“The military forces of the revolutionary adversary are diffuse. One is never sure whether one has destroyed them unless one is ready to destroy a large portion of the population, and this usually conflicts with the political aim of the war and hence also violates a fundamental Clausewitzian principle”

“In the case of strategy and conscience, I am not sure. Here I believe, is essential incompatibility, not merely a result of misunderstanding. I do not believe one can bring both into focus. One cannot play chess if one becomes aware of the pieces as living souls and of the fact that the Whites and the Blacks have more in common with each other than with the players. Suddenly one loses all interest in who will be champion.”

“The outstanding feature of behavior is that it is often quite easy to recognize but extremely difficult or impossible to describe with precision.”

“For a general semanticist, communication is not merely words in proper order properly inflected (as for the grammarian) or assertions in proper relation to each other (as for the logician) or assertions in proper relation to referents (as for the semanticist), but all these together, with the chain of 'fact to nervous system to language to nervous system to action.”

“A theorem is a proposition which is a strict logical consequence of certain definitions and other propositions”

“The transition from the concept of information in the technical (communication engineering) sense to the semantic (theory of meaning) sense was indeed difficult, if not impossible.”

“It is misleading in a crucial way to view information as something that can be poured into an empty vessel, like a fluid or even energy.”

“[It is a] well-known fact that the likely contacts of two individuals who are closely acquainted tend to be more overlapping than those of two arbitrarily selected individuals”

“A fundamental value in the scientific outlook is concern with the best available map of reality. The scientist will always seek a description of events which enables him to predict most by assuming least. He thus already prefers a particular form of behavior. If moralities are systems of preferences, here is at least one point at which science cannot be said to be completely without preferences. Science prefers good maps.”

“No map contains all the information about the territory it represents. The road map we get at the gasoline station may show all the roads in the state, but it will not as a rule show latitude and longitude. A physical map goes into details about the topography of a country but is indifferent to political boundaries. Furthermore, the scale of the map makes a big difference. The smaller the scale the less features will be shown.”

“Whether sociology can ever become a full-fledged "science" (a description of a class of events predictable on the basis of deductions from a constant rationale) depends on whether the terms which sociologists employ to describe events can be analyzed into quantifiable observables.”

“The first attempts to consider the behavior of so-called "random neural nets" in a systematic way have led to a series of problems concerned with relations between the "structure" and the "function" of such nets. The "structure" of a random net is not a clearly defined topological manifold such as could be used to describe a circuit with explicitly given connections. In a random neural net, one does not speak of "this" neuron synapsing on "that" one, but rather in terms of tendencies and probabilities associated with points or regions in the net.”
