That particular discussion, to which Thomas Kuhn also contributed, also has not yet reached closure which leaves me with the feeling that science might best be described as a particular form of behavior by practitioners who possess certain qualifications and engage in certain rituals approved by members of the scientific tribe. Thus, one definition of science is that it is whatever it is that scientists do in the name of science ( a contextual and social definition). Making coffee would not be scientific activity but reading a professional book or entertaining colleagues with stimulating thoughts and writings would be. From this perspective, employing the scientific method is merely a particular form of engaging in scientific practice without judging the outcome of that scientific practice. Relying upon the scientific method by unlicensed practitioners would not result in science but in lay knowledge. This means that authoritative statements by members of scientific community are automatically given a certain truth value. "Professor X says this", "scientific study Y demonstrates that . . ." should all be considered as scientific statements because they are issued as authorative statements in the name of science. This interpretation of science discounts the role of Edward Teller as a credible spokesman in the area of nuclear weapons policy in foreign affairs. The "licensing" of the practitioners derives from the formalization of the training and education in the particular body of knowledge: eg. a university degree is a form of license. Scientific knowledge can differentiate itself from other forms of knowledge on the basis of attempts (but not necesssarily success) at formalization. Physical sciences study phenomena which lend themselves to better quantification (they do have better metrics!) and higher levels of formalization. The deterministic bodies of knowledge of the physical science allow for better prediction than the heavily probabilistic bodies of knowledge of the social science which facilitate explanation more so than prediction. I am not sure if a lack of predictive power or lack of availability of the scientific method (experimental design in its many flavors) makes anyone less a scientist. The social sciences are rich in description and insight which in my judgment compensates for a lack of hierarchical, deductive formal knowledge. >From this point of view computer science is science if it involves building a body of knowledge with attempts at formulating rules in some consistent and verfiable manner by a body of trained practitioners. Medieval alchemy also qualifies due to its apprenticeship program (rules for admitting members) and its rules for building knowledge. Fortunately, we have better rules now. Acco
