Positivist

Positivism is a philosophical theory stating that positive knowledge is based on natural phenomena and their properties and relations. Thus, information derived from sensory experience, interpreted through reason and logic, forms the exclusive source of all authoritative knowledge. Positivism holds that valid knowledge (certitude or truth) is found only in this derived knowledge.

Verified data (positive facts) received from the senses are known as empirical evidence; thus positivism is based on empiricism.

Positivism also holds that society, like the physical world, operates according to general laws. Introspective and intuitive knowledge is rejected, as is metaphysics and theology. Although the positivist approach has been a recurrent theme in the history of western thought, the modern sense of the approach was formulated by the philosopher Auguste Comte in the early 19th century. Comte argued that, much as the physical world operates according to gravity and other absolute laws, so does society, and further developed positivism into a Religion of Humanity.

The English noun positivism was re-imported in the 19th century from the French word positivisme, derived from positif in its philosophical sense of 'imposed on the mind by experience'. The corresponding adjective (lat. positīvus 'arbitrarily imposed', from 'put in place') has been used in similar sense to discuss law (positive law compared to natural law) since the time of Chaucer.

Positivism is part of a more general ancient quarrel between philosophy and poetry, notably laid out by Plato and later reformulated as a quarrel between the sciences and the humanities, Plato elaborates a critique of poetry from the point of view of philosophy in his dialogues Phaedrus 245a, Symposium 209a, Republic 398a, Laws 817 b-d and Ion.Wilhelm Dilthey popularized the distinction between Geisteswissenschaft (humanities) and Naturwissenschaften (natural sciences).
