For Dewey, the individual only becomes a meaningful concept when considered as an inherent part of his society.
Heidegger's philosophy is based on the idea that man is a being who seeks what is not. His life project can be eliminated by the pressures of life and daily life, which leads man to isolate himself from himself. Heidegger also worked on the concept of anguish, from which man transcends or lets himself be dominated by them. Thus, man would be an unfinished project.
"Phenomenological reduction," as Husserl puts it, is the process of "bracketing" the existence of the contents of consciousness, or experiences, and of the self as a psycho physical subject or existential support of consciousness, thus reduced to pure or transcendental self.
