I expect 'opposites' will dominate this discussion. It is axiomatic in the West and common in the East to deal with dichotomies rather than incremental differences. There is much linguistic evidence that antonyms are the most fundamental distinction, and this is supported by neurological evidence as well as cerebral traumas. Opposites are also the first reliable intellectual distinction mastered by young children.
