The connection between [Weil and Heidegger] can be seen in what Heidegger calls the “subjectivism” of modern philosophy (which cuts people off from each other and from the world and Presence and confines them in a metaphysical privacy) and what Simone Weil calls “personalism” (which reduces the human being entirely to the dimensions of the I and we, the psychological and the social, not recognizing anything about them that belongs to the superpersonal). The modern oppression of the individual by the social (found in both Communist and non-Communist states) and the metaphysical humanism of scientism and technocracy, while they may appear to have nothing in common, actually contain the same element, a false individualism that produces the lonely, locked-away solitary ego, a ready victim for the exploitations and manipulations of mob consciousness. This is the nationalistic or ideological man whose normal and sane intelligence has been smothered by commercial and political indoctrination. For both Heidegger and Weil, this is the closed private individualism of modern philosophy, the counterpart of the world of scientific and technological objects. The absolute privacy of the Cartesian thinking is the horror of the modern human self.
In answer to this, Heidegger finds the essence of the human being in an openness to Being as Presence, an openness receptive to all its self-revealings and self-concealings, while Simone Weil finds a supernatural element in every human soul, which is the basis for all justice, the universal expectation that good will be done to us.
