Abstract
Due to the exponential growth of science and, recently, the explosive expansion of the extrascientific information of computerized 'Data' of all sorts, a New Cognitive Order of Society comes into existence. The invalidation of the 'Old Order' with its classical conditions for the production, processing, application and fairly equal social distribution of knowledge is a result of technological developments, especially of the rise of Information Technology. What may be called the Cognitive-Technological Complex is rapidly developing. This causes a fundamental change of the situation of knowledge in the Information Society so-called. It confronts philosophy with the task, 'to climb up' the growing information mountains and to analyse its contents and structures, i.e., old and new sorts of knowledge in huge quantities and mixtures, with different rationality-structures, etc. This cannot be done without new theories of knowledge and rationality. What is practically needed, involves a new philosopher's comprehensive competence for handling the whole information stuff, ranging from classical theory-knowledge to modern data-knowledge. Technical competence for computers is not enough. Thus, information technology opens philosophy and philosophers an unexpected, perhaps undeserved chance to keep pace with the most progressive cognitive and technological developments. To take advantage of the new situation of knowledge and to explore the constitutive conditions of the New Cognitive Order is the first task of contemporary philosophy, in close cooperation with all cognitive sciences
