小世界 Small World

人活在他的主觀上小世界中，是指他所承認的世界小於他所認知的世界。	A person is living in his subjectively small world means that the world he admits is smaller than the world he knows.
人活在他的客觀上小世界中，是指他所認知的世界小於他所承認的世界。	A person is living in his objectively small world means that the world he knows is smaller than the world he admits.
另外，人不可能認知全世界，故不必討論這個例子。	In addition, a person is impossible to know the whole world, so we do not have to discuss this case.
