Abstract
In systems science, the category of goal is restored in its rights. However, the current studies are mainly confined to closed systems and are of an object-based character although the teleological principle, defining a system, is inapplicable to the object. The issues associated with the possibility of the subject to be included in systems analysis are discussed as well as the approaches to the research into evolutionary processes in open systems. In addition to this, the problems in a subjectbased approach in psychosemantics and quantum physics are considered.
