{"product_id":"9783934616776","title":"Principles of Sociology: Vol. I-IV.","description":"In 'The Principles of Sociology' Spencer rejected the sociology of Auguste Comte's positivism and made some valuable contributions to early sociology, attempting to reformulate social science in terms of evolutionary biology. A 'social organism' evolved from the simpler state to the more complex according to the universal law of evolution. Spencer's theories of laissez-faire, survival-of-the-fittest and minimal human interference in the processes of natural law had an enduring influence on thinkers and politicians such as Friedrich Hayek, Milton Friedman and Margaret Thatcher.","brand":"heptagon","offers":[{"title":"Default Title","offer_id":47164804038896,"sku":"9783934616776","price":7.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0737\/7593\/9824\/files\/9783934616776_p0.jpg?v=1763703394","url":"https:\/\/shop-qa.barnesandnoble.com\/products\/9783934616776","provider":"Barnes \u0026 Noble (DEV)","version":"1.0","type":"link"}
