Auguste Comte, a pioneer in sociology, proposed the law of three stages of societal development: theological, metaphysical, and scientific, emphasizing the evolution of human thought. He introduced the hierarchy of sciences, positioning sociology at its apex, and distinguished between social statics (the study of societal structure) and social dynamics (the study of societal progress). Comte also advocated for a 'religion of humanity' to guide moral unity, rejecting traditional religious concepts in favor of a positivist worldview focused on empirical knowledge.
