Alan Watts - Out of the Trap

So then, just as we think solids more real than space, so, in the same way, we give weight to positive-the Yang aspect of things, rather than Yin-the negative. And we are therefore hung up on the quest for those positive things in life: the good, the pleasurable, and so on, and think that somehow we can possess them away from, and apart from, their polar opposites. Never forget that this is not simply a case of opposition. Polarity and mere opposition are a little different in concept, because when we say that these opposites are polar, we mean that they are in fact, the abstract terms, or ends, of a sort of continuum that joins them. In the same way, the two sides of a coin are Euclidian surfaces of a solid: the coin is one; the magnet is one. But the heads and tails are different, and the north and south poles of the magnet are different. So, what you have here is the paradoxical situation of identical differences-explicitly different, but implicitly one.
