When every one recognizes beauty to be only a masquerade, then it is simply ugliness. In the same way goodness, if it is not sincere, is not goodness. So existence and non-existence are incompatible. The difficult and easy are mutually opposites. Just as the long and the short, p. 12 the high and the low, the loud and soft, the before and the behind, are all opposites and each reveals the other.
Therefore the wise man is not conspicuous in his affairs or given to much talking. Though troubles arise he is not irritated. He produces but does not own; he acts but claims no merit; he builds but does not dwell therein; and because he does not dwell therein he never departs.
