Back to the Kantian Noumenon The ongoing debates over the religious pluralism of John Hick have highlighted what are, in effect, two primary modes of visualizing doctrinal and experiential diversity across the world's religious traditions. The traditional strategy, that spans the options labelled as 'exclusivism' and 'inclusivism' in the literature, is centred on the concrete focus of Christ, with other religions placed at varying distances of spiritual efficacy with respect to this foundational truth. The 'pluralist' strategy associated with Hick consists of re-imagining these religions, each with its distinctive focus such as Allah, Brahman, or Vishnu, as charged with transformational capacity not because they are literally accurate descriptions of the ultimate but because they are capable of metaphorically gesturing towards this ultimate. A vital debate emerges at this point between the defenders of this pluralist hypothesis and its detractors over whether these foci are metaphysically real or unreal. Hick's pluralism faces the following dilemmaif these foci are taken as absolutely real, their specific characterizations would be attributed to the ultimate which he argues is ineffable, but if they are taken as absolutely unreal, he would have accepted a naturalist interpretation of religious discourse which he otherwise rejects. With this conceptual background in mind, we shall pursue three primary objectives in this essay. First, we shall examine certain conceptual instabilities in Hick's pluralism in the light of S. Radhakrishnan's approach to religious diversity which is based on a reformulation of classical Advaita. Second, our analysis of Hick's and Radhakrishnan's views will illuminate the significance of ontology in certain proposed typologies of religious pluralism. Third, we will be able to revisit, through this dialogue between Hick and Radhakrishnan, the intensely vexed question of whether Hick's version of pluralism is in fact a form of covert exclusivism. The comparative perspective that we shall explore here would seem promising on at least three accounts. First, Hick himself often quoted Radhakrishnan's translations from the Upanishads in support of his own claims about divine ineffability, transformative experience, and religious pluralism. Indeed, Radhakrishnan's statements on the relation between the ultimate and the world's religions can often sound Hickian. For instance, emphasising that the religious traditions are diverse culturally-shaped attempts on the part of human beings to respond to the ultimate, he argued: 'Religious experience is not the pure unvarnished presentment of the real in itself, but is the presentment of the real already influenced by the ideas and prepossessions of the perceiving mind' (Radhakrishnan, 1927:24). Secondly, both Hick and Radhakrishnan operated with an appearance-reality distinction in developing their views on the significance of religious diversity. Thirdly, and crucially, while Hick adapted this distinction from Kant, Radhakrishnan derived it ultimately ...
