Positivism is the philosophy of science that information derived from logical and mathematical treatments and reports of sensory experience is the exclusive source of all authoritative knowledge,[1] and that there is valid knowledge (truth) only in this derived knowledge.[2] Verified data received from the senses are known as empirical evidence.[1] Positivism holds that society, like the physical world, operates according to general laws. Introspective and intuitive knowledge is rejected. Although the positivist approach has been a recurrent theme in the history of western thought,[3] the modern sense of the approach was developed by the philosopher and founding sociologist Auguste Comte in the early 19th century.[4] Comte argued that, much as the physical world operates according to gravity and other absolute laws, so does society.[5]
