Positivism is a philosophy of science based on the view that information derived from logical and mathematical treatments and reports of sensory experience is the exclusive source of all authoritative knowledge, and that there is valid knowledge (truth) only in scientific knowledge. Verified data received from the senses are known as empirical evidence. This view 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, the modern sense of the approach was developed by the philosopher and founding sociologist Auguste Comte in the early 19th century. Comte argued that, much as the physical world operates according to gravity and other absolute laws, so also does society.
