SOME UNSOLVED PROBLEMS OF THE THEORY OF ACTIVITY

The paper investigates the contemporary state of the multidisciplinary theory of activity, its dialectical-materialistic comprehension resting upon achievements of the classics of philosophy. An analysis is given of main, still unsolved, problems of this theory connected with the necessity of defining the concept of transformation as an important characteristic of human activity, of the ratio of its collective and individual forms, of the diversity of the structure of activity, which is studied by various disciplines, of the bases of classification of kinds of activity, of the peculiarities of its interdisciplinary research, etc.
