means The view that all knowledge and understanding comes from some particular perspective, so there's no neutral 'view from nowhere' — only vantage points, each partial.

from Built from 'perspective' (from Latin 'perspicere,' to look through or see clearly — 'per' meaning through, 'specere' meaning to look) plus the philosophical suffix '-ism.' The word crystallized around Nietzsche's late-19th-century writings, where he argued that all seeing is seeing-from-somewhere, borrowing the optics of 'perspective' as a metaphor for the unavoidable angle baked into every claim to truth.
