The so-called 'reasoning' for ordinary man is built on a common,
fundamental but not well-known aspect in philosophy.
There is an external world that objectively exists
and is independent of our interpretation.
Therefore, every morning after we wake up from dreams,
we can bravely get rid of the nightmare,
and return to the cruel and cold external world.
In case this fundamental aspect collapses,
our mind and reasoning will totally go into chaos.
- Chinese Thinker, Kam Kwun Tao
