Lu Xun: The world is really a difficult place. It is not a good word to say that a person is "unsophisticated", nor is it a good word to say that he is "sophisticated".

Balzac: There are no principles in the world, only the world, no rules, only the status quo. Smart people integrate into the world and current affairs and dominate at will.

Chesterfield: The absurd idea of inexperienced and methodical people is that they don't like the patience of sophisticated people.

Bacon: There are many sophisticated people who can read people's temper and personality, but they are not really learned people. Such people are good at conspiracy rather than research.
