The relationship between the perspectives of the perennialist tradition of pluralistic thinking and the kind of apophaticism articulated in the patristic era by Gregory of Nyssa and in the modern era by Vladimir Lossky is examined, and parallels in Islamic thinking are noted. The kind of intuitive apprehension of divine realities associated with the ancient Greek concept of the nous is seen as central to this relationship. The perennialist distinction between esoteric and exoteric aspects of any faith tradition is examined in this context, and Lossky’s sense of the importance of antinomy is seen as significant for rejecting the kind of critique of pluralism that is based on the notion that the doctrinal statements of different faith traditions should be seen as philosophical ‘truth claims’.
