诐辞知其所蔽,淫辞知其所陷,邪辞知其所离,遁辞知其所穷。· When one's words are one-sided,I know how the mind of the speaker is clouded over. When one's words are extravagant,I know how the mind is fallen and sunk. When one's words are all depraved,I know how the mind is departed from principle. When one's words are evasive,I know how the mind is at its wit's end.
