Light is meaningful only in relation to darkness, and truth presupposes error. It is these mingled opposites which people our life, which make it pungent, intoxicating. We only exist in terms of this conflict, in the zone where black and white clash.
The world is not dialectical -- it is sworn to extremes, not to equilibrium, sworn to radical antagonism, not to reconciliation or synthesis. This is also the principle of evil.
Without contraries is no progression. Attraction and repulsion, reason and energy, love and hate, are necessary to human existence.
The beginning, middle, and end of the birth, growth, and perfection of whatever we behold is from contraries, by contraries, and to contraries; and whatever contrariety is, there is action and reaction, there is motion, diversity, multitude, and order, there are degrees, succession and vicissitude.
Every sweet has its sour; every evil its good.
The dictate of the light says: Know yourself and what you are. The dark replies, By all means, but then become afraid.
It happens as one sees in cages: the birds who are outside despair of ever getting in, and those within are equally desirous of getting out
In me the tiger sniffs the rose.
Every moment of light and dark is a miracle.
