Abstract
Among the foundations of the sciences and the humanities should be counted the norms and values which they necessarily presuppose. This argument requires us to view science and scholarship (systematic cognitive activity) as deliberate and complex forms of human activity . Human action can be ('rationally') guided and legitimated only by reference to norms and values. It is shown that, historically, there are at least three distinct traditions: (1) The Platonic-Aristotelian, (2) the Baconian, and (3) the Weberian. The first is based on the value of 'self-realization'; the second on welfare as a function of technological control; and the third on the justification of science through the Wertfreiheit of its practitioners. It is then argued that when we add (4), a set of general methodological norms, and (5), the ideal of academic freedom or autonomy, we have before us an 'ideology of cognitive activity' which it is now important to study, historically, critically, and constructively. For some such ideology is as indispensable as internal and external demands for legitimation (of science, etc.) are now both inescapable and justified.
