Positivism is a philosophical and methodological stance asserting that genuine knowledge is exclusively derived from empirical observation and sensory experience, verifiable through scientific methods. It advocates for the systematic study of observable phenomena to discover universal laws, rejecting metaphysical or non-empirical forms of inquiry. This approach emphasizes objectivity, empirical data, and the search for causal relationships, significantly influencing the development of quantitative research methodologies and shaping the epistemology of various scientific disciplines.
