Polarity (n.) is what the duality of knower and known becomes: two poles of a single event happening, not to me or from me, but of itself.
Polarity (n.) is the structure of the psyche as of all natural processes, which arise from a less probable state of tension; consciousness is loath to admit the polarity of its own background, yet draws its energy from it.
