Using data from an ethnographic study of tarot divination, occult claims to knowledge are analyzed and interpreted. Attention is focused on the procedures parties to occult divination employ to claim and sustain what they regard as extraordinary knowledge. This view of occult knowledge stands opposed to efforts to discredit occult claims as unscientific or the result of psychosocial conditions like deprivation and marginality. Like knowledge in general, occult knowledge is a product of sociohistorical influences, interactional negotiation, and interpretation. The challenge for sociology therefore is the pursuit of the social interactional and historical processes whereby knowledge and interpretation are accomplished in everyday life.
