Overview

Positivism holds that genuine knowledge is limited to what can be observed, measured, and verified by the scientific method. Auguste Comte proposed that humanity progresses through three stages — theological, metaphysical, and finally positive (scientific) — and sought to found a 'social physics' (sociology) that would bring scientific rigor to the study of society. John Stuart Mill corresponded with Comte and took up part of his programme, but Auguste Comte and Positivism (1865) is substantially a critique, and Mill rejected the later system outright; he belongs to this entry as a critical interlocutor rather than as a positivist.

Key ideas

  • Law of Three Stages: Human thought evolves from theological (divine explanations) through metaphysical (abstract forces) to positive (scientific laws based on observation). Each stage replaces the last.
  • Anti-Metaphysics: Questions about ultimate reality, first causes, or essences lie beyond the reach of positive knowledge and belong to a superseded stage of thought. Science describes regularities in observable phenomena — nothing more is needed or possible.
  • Unity of Science: All genuine sciences share a single method. Sociology, as the 'queen of sciences,' applies this method to human society, enabling rational social planning.
