The English sociologist Roy Wallis argues that a sect is characterized by "epistemological authoritarianism": sects possess some authoritative locus for the legitimate attribution of heresy. According to Wallis, "sects lay a claim to possess unique and privileged access to the truth or salvation" and "their committed adherents typically regard all those outside the confines of the collectivity as 'in error'". He contrasts this with a cult that he described as characterized by "epistemological individualism" by which he means that "the cult has no clear locus of final authority beyond the individual member."
