All of the dualities of live are mutually depend and mutually necessary. Here the quote about from Laotse in:
Tao Te Ching (21-2) In the world, everyone recognize beauty as beauty, since the ugly is also there. Everyone recognize goodness as goodness, since evil is also there.
When one searches only for beauty one stigmatizes the ugly. When people see beauty as pure beauty they view the ugly disparagingly. In valuing the good as purely good their judgement is based upon the idea of bad. But the universal manifests through the division of two from one, each depends on its opposite. So what ? One exist because the opposite exist ! If one would not exist the other would also not exist. Mhhhh, then it would be no separation no judgement means paradise, Shangri-La, nirvana, heaven or Wuji like the daoist are saying.
