“These three classes of problems—determination of significant fact, matching of facts with theory, and articulation of theory—exhaust, I think, the literature of normal science, both empirical and theoretical. They do not, of course, quite exhaust the entire literature of science. There are also extraordinary problems, and it may well be their resolution that makes the scientific enterprise as a whole so particularly worthwhile. But extraordinary problems are not to be had for the asking. They emerge only on special occasions prepared by the advance of normal research.”

“The philosophy of science is concerned with how you decide if a scientific finding is correct or true. You have to establish criteria to determine if the finding or theory is valid. Validity is a fundamental problem in the philosophy of science, but the fundamental problem in the philosophy of scientific administration is the question of value.”

Alvin M. Weinberg (1915–2006) American nuclear physicist

Two scientific activities are equally valid if they achieve results that are true. Now, how do you decide which activity is more valuable? The question of value is the basic question that the scientific administrator asks so that decisions can be made about funding priorities.

“The body of scientific evidence supporting creation science is as strong as that supporting evolution. In fact, it may be stronger…. The evidence for evolution is far less compelling than we have been led to believe. Evolution is not a scientific "fact," since it cannot actually be observed in a laboratory. Rather, evolution is merely a scientific theory or "guess."… It is a very bad guess at that. The scientific problems with evolution are so serious that it could accurately be termed a "myth."”

“The future mathematical statistician needs early contacts with experimental sciences. He needs them because, at this stage of the development of statistics, the expeimental sciences are sources of theoretical problems. Also, he needs them because in almost any imaginable job which he may get after graduation, he will be called upon to apply his theory to experimental or observational problems.”

“Normal science, the puzzle-solving activity we have just examined, is a highly cumulative enterprise, eminently successful in its aim, the steady extension of the scope and precision of scientific knowledge. In all these respects it fits with great precision the most usual image of scientific work. Yet one standard product of the scientific enterprise is missing. Normal science does not aim at novelties of fact or theory and, when successful, finds none.”

“Today our main problem is that of organized complexity. Concepts like those of organization, wholeness, directiveness, teleology, control, self-regulation, differentiation and the like are alien to conventional physics. However, they pop up everywhere in the biological, behavioural and social sciences, and are, in fact, indispensable for dealing with living organisms or social groups. Thus, a basic problem posed to modern science is a general theory of organization.”

However, they pop up everywhere in the biological, behavioral, and social sciences and are, in fact, indispensable for dealing with living organisms or social groups. Thus, a basic problem posed to modem science is a general theory of organization. General Systems Theory is, in principle, capable of giving exact definitions for such concepts.”

“A major social problem we face today is how to control the political process that is eroding the free enterprise market system. Although I am pessimistic that we will in fact ever resolve this problem completely, we will surely never solve it unless we develop a viable positive theory of the political process. Such a political theory will not be complete until we also have developed a theory that explains why we get the results we do out of the mass media.”

“The problem of the re-organization of science will not be solved by administrative or financial changes. It will also be necessary to reorganise in a most comprehensive way the whole apparatus of scientific communication.”
