‘Wú zhī’ literally means ‘without knowledge’ — ‘wú’ meaning ‘not’ or ‘without’, and ‘zhī’ meaning ‘to know’ or ‘knowledge’. Together, it forms a noun meaning ‘ignorance’: the state of lacking knowledge, awareness, or understanding about something. Unlike the English word ‘ignorance’, which can be neutral or pejorative depending on context, ‘wú zhī’ often carries a mild negative connotation, suggesting a deficiency that may lead to poor judgment or inappropriate behavior.

This term is commonly used in formal or reflective contexts — in education, moral discussions, or social commentary — rather than casual speech. It’s not typically used to describe temporary or harmless lack of information (e.g., ‘I don’t know the bus schedule’), but rather deeper, systemic, or socially consequential unawareness — such as ignorance of cultural norms, scientific facts, or ethical responsibilities. It frequently appears in phrases like ‘无知者无畏’ (the ignorant fear nothing) or ‘摆脱无知’ (overcome ignorance).
