Abstract
The formation of a new scientific picture of the world is connected with the necessity of subjectivity. This subjectivity posits no limits for the scientific aspects of cognitive processes, but embraces a comprehensive world of spiritual activity. To choose the most effective model of social behavior, it is important to have an adequate knowledge of reality. Modern science reflects the vagueness of reality and, in consequence, the impossibility of using classical approaches. Increasingly, the negative phenomena of the surrounding world reflects the complexity of natural and socio-natural systems, especially on the global scale. Restrictions of the classical approaches to this complexity can be overcome within the synergistic theories or hierarchical systems theory that are becoming more and more popular. The necessity of appeal to modern theories, initiated as the result of ecological crises, stimulates the processes of new paradigm formation in science, acting often in spite of the needs and motives of society.
