The appearance of nuclear weapons suddenly made the extinction of humanity a distinct possibility. In view of this obverse side of scientific progress, attitudes toward science in the general population became ambivalent, at times bordering on hostility. It is argued that to a great extent the scientists themselves are responsible for the tarnished image of science. Accordingly they should restore science to its role of furthering human welfare and, above all, as a source of enlightenment. In our age enlightenment entails (...) emancipating humanity from superstitions generated by the cooptation of science in the service of power. (shrink)

In relating the problem of comparison to that of conceptualization, Dr. Sjoberg brings into focus a central methodological problem of social science. For to compare is to discover unity in diversity and differences among similarities, that is, to uncover structure. The first act in this process is to name the parts and the relations among them, and naming, of course, both stems from and induces conceptualizations.

Let us begin by proposing a sort of common denominator of the various conceptions of rationality, some feature that underlies practically all its definitions.

Almost anyone seriously interested in decision theory will name John von Neumann's (1928) Minimax Theorem as its foundation, whereas Utility and Rationality are imagined to be the twin towers on which the theory rests. Yet, experimental results and real-life observations seldom support that expectation. Over two centuries ago, Hume (1739–40/1978) put his finger on the discrepancy. “Reason,” he wrote “is, and ought to be the slave of passions, and can never pretend to any other office than to serve and obey (...) them.” In other words, effective means to reach specific goals can be prescribed, but not the goals. A wide range of experimental results and daily life behavior support this dictum. (shrink)

It remains to summarize the contributions which each of the three disciplines discussed here is making toward the development of a science of man. "Significs" makes a study of the effects on human behavior of the linguistic aspects of the evaluative process, the most distinctly human aspect of the behavior of the human organism. "Mathematical Biophysics" seeks to describe the events associated with evaluative processes in physico-mathematical terms. "Cybernetics" is discovering important invariants common to these processes and others, particularly those (...) observed in man-made machines and in situations which lend themselves to description in thermo-dynamic or statistical (order -- chaos) terms.
