"The Self is not an object or even a goal, but an activity, a process. Gerard Manley Hopkins expressed it beautifully: "...What I do is me; for that I came!"
The Self is the purposiveness of the organism, the teleological intention of becoming itself as fully as it can. As the rhizome contains the fullness of the flower, so the unified self-hood of the organism is expressed through the variegations of root, stem, flower, pistil and stamen. The Self is unknowable, though its intentionality may be inferred from its expression through the venues of body, affect, cognition, symptom, dream image and the like...As the Self embodies the totality of the organism and its mysterious, autonomous activity, so we may never know it fully any more than a swimmer could know the ocean, or a thinker conjugate the dome of Heaven. Hence the fragile ego must content itself with "a sense" of Self, the Self forever unknown, unknowable.
Accordingly, we are always left with partiality though we may believe we know ourselves fully. There is, in fact, no greater folly than such a hubristic claim."
