AbstractIn this article, the phenomenon of global thinking is discussed. The main characteristics of logical thinking (substantiality, sequentiality, dichotomy, estimation, etc.) and systematic thinking (the observer′s position and restriction of dichotomizing approach, etc.) are described. It is emphasized that the ability to think globally has an evolutionary context, being formed in mankind in general and in each specific person in the course of his or her development. The characteristics of systematic thinking are described as a foreshortening of the conventional forms of Human existence: the individual, the subject of activity, the personality, and the individuality; and also novel, not yet defined, realities of ″the Planetary Man″ and ″the Metagalactic Man″ are revealed. It is to be stressed that training to think systematically as a characteristic of the large-scale forms of Human existence is one of the important tasks of education for sustainable development.
