Philosophical thought, both in the past and today, is integrally intertwined with psychology in its various dimensions. Cartesian reflections by M. K. Mamardashvili determine the possibility of approaching the psychological understanding of the “New Philosophy”, as well as general scientific categories of consciousness and awareness. Comparison of the content of the categories of consciousness and awareness in the Cartesian formulation and in the modern “Science of consciousness” allows us to expand the understanding of the driving forces of human thought in its objective and subjective (personal) manifestations. Individual outstanding carriers of consciousness of various historical eras, objectifying their perception, emotions, intellect and will in a free dialogue (internal communication) in the language of philosophy, turn out, paradoxically, psychologically consolidated in a diverse continuum of real existence in combination with individual forms of other existence (certain or other types of transcendence).
