USAGE:
A somewhat formal and literary word. 知性 implies a refined, cultivated form of intelligence — the kind associated with educated, thoughtful people. It differs from 知能, which refers more to raw cognitive ability or IQ.
KANJI:
知 means "to know" or "wisdom" and 性 means "nature" or "quality." The compound refers to the inherent quality of knowing and understanding.
CONTRAST:
- 知能: cognitive ability, IQ (more clinical/measurable)
- 知恵: practical wisdom, cleverness (more applied/everyday)
- 知性: intellect (more cultivated/sophisticated)
COMMON COLLOCATIONS:
- 知性を磨く: to cultivate one's intellect
