 By emphasizing the primacy of ethical development as instrumental to the formation of consciousness, his thoughts presaged those of Vivekananda.He attacked Vaishnava religion as he felt that natural or spontaneous religion based on the traditions of bhakti did not help in the development of critical rational faculties, and paradoxically served to keep the masses illiterate, and uncritical.His critical appraisal of Brahmo followers (primarily the followers of Keshub Chunder Sen's New Dispensation) as spiritual deviants, and his emphasis on logical empiricism earned him detractors both with the Brahmo Samaj (particularly the followers of Keshub Chunder Sen), and in the wider Hindu society, who criticized his efforts as effete scholasticism.
