“Philosophy starts by doubting the reality of the perceptible world, of the world of objects and things.”[1] But this is not enough. Philosophical theory should be primarily concerned with the thinking subject, and the meaning and purpose of his existence. “Reality is originally part of the inner existence, of the inner spiritual communion and community, but it becomes degraded in the process of objectification and by having to submit to social necessities.”[2] “To exist, is for man to dwell within himself, in his own authentic world, rather than to be at the mercy of the social and biological world.”[3]
Like Plato, Descartes expresses skepticism about physical reality; in Descartes’ case, whether external reality exists at all, and whether we can have knowledge of it. He goes beyond Plato by discovering the knowing subject. Plato’s conception of noumenal reality is universalist and has nothing that is essentially personal about it. It is populated by hypostasized abstractions, the Forms, but also a living god – the Form of the Good. Descartes’ notion of the existential interior stops short at the subject as the thinking thing. Cogito ergo sum; I am thinking therefore I am. Who is this I? Descartes asks. He replies, a thing that thinks. Multiple problems are immediately evident. One is the severely restricted and inadequate spiritual vision. There is no beauty, justice, or truth, and no God. Another is the restriction of the subject to a thinking thing. Feelings and volition are as much a part of the subject as thought, but these are simply omitted. So, there is a subject, but it is truncated and misdescribed and it would take Kant to identify the existential subject with freedom and the phenomenal world with determinism, though Kant continues to associate the noumenal with the intellect alone.
