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 not conflict: + and −, north and south, are two faces of one system, and lose either one and the whole system disappears.
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.
Polarity (n.) is the price of being real: the self is a union of opposites precisely because nothing can be real without polarity.
