90.以同而異—— 出自《睽·象》
今譯：既綜合事物的共同處，又分析其中的差異。
衍言：這個世界千絲萬縷，必須學會以科學眼光分析自然與社會中的事物。
《周易》小詞典：《睽》，卦名。睽有乖離、不同的意思，睽卦反映了世界是相反的事物構成，而正是由相反才相成了和諧。
The superior man, where there is a general agreement, yet admits diversity.——- from The Great Symbolism, Kui
Modern interpretation: Synthesize what is in common and analyze what is of difference.
Moral: In such a complicated world, we should learn to view everything of the nature and society in a scientific light.
Glossary: Kui denotes a social state, in which division and mutual alienation prevail. This hexagram presents the fact that the world is made up of opposites, which make social harmony come into being.
