"Sociology does not ‘negate’ philosophy, in the sense of taking over the hidden content of philosophy and carrying it into social theory and practice, but sets itself up as a realm apart from philosophy, with a province and truth of its own. Comte is rightly held to be the inaugurator of this separation between philosophy and sociology. P. 375"
