means The view that genuine knowledge comes only from science — observation, experiment, and logical proof — and that metaphysics or theology can't produce real knowledge at all.

from From Latin 'positivus' meaning 'settled, laid down,' via French 'positif.' The philosophical sense was built by Auguste Comte in 19th-century France, who used 'positive' to mean knowledge grounded in verified fact rather than speculation — he imagined human thought evolving through theological and metaphysical stages before arriving at this final, 'positive' scientific stage.
