 On the whole, scientific humanism is designed to avoid the extremes. It qualifies, according to Feigl, as “a tenable middle ground between the relativists and the absolutists in morals” (1981, p. 417). In contrast to relativism, it is assumed that certain basic human values, such as justice, fairness or equality, are universally applicable. However, in contrast to (for instance, Kantian) absolutism, it is at the same time assumed that those values are related to human interests and thus empirically variable. They “may have come out of the natural development of human beings in the social context” (ibid., p. 420), and they can only be justified pragmatically (by way of vindication). But, Feigl maintains, that does not make them arbitrary: “If we dig deeper into human nature we find that in some social contexts certain moral ideals inevitably work themselves out” (ibid., p. 418). In the “age of scientific enlightenment” (ibid., p. 420) an ethically disinterested or even cynical view of the world is therefore out of place: “Psychology points in the direction of human needs and interests that must be satisfied. And in the social context, certain traffic rules simply have to be obeyed if we are to survive as a society. Thus we have ideals of justice and equality.” (ibid.)
