The theism-atheism debate is foreign to many Mahāyāna Buddhist thinkers such as the Japanese Zen Master Dōgen. Nevertheless, his philosophy of ‘expression’ is able to shine a new light on the various incarnations of this debate throughout history. This paper will explore a/theism from Dōgen’s philosophical standpoint. Dōgen introduces the notion of ‘expression’ to describe the concomitant vertical and horizontal relationships of the religious project, namely the relationship between the individual and the divine as well as the relationship among a (...) multiplicity of individuals, each of which Dōgen conceives of as an expression of the divine and/or the oneness of the cosmos. Dōgen’s philosophy presupposes the ‘way of emptiness’ and Chengguan’s ‘four dharma worlds’. To Dōgen, the former indicates the conventional nature of predication and signification, while the latter denotes the existential interwovenness of numerous individuals and the divine oneness of the cosmos. Such a philosophy implies that all truth claims and philosophical positions are mere intellectual and discursive constructions that are formulated against a perceived other. Therefore, Dōgen observes laconically that ‘when one side is expressed, the other is obscured’ or, as Dōgen says elsewhere, ‘when expression is expressed, non-expression is not expressed.’ Dōgen’s philosophical framework provides some interesting insights about one or more discourses on atheism: Again, the basic assumption is that all philosophical paradigms, systems, and positions are devoid of an absolute truth value, framed in a specific cultural and historical context which they express, and formulated vis-à-vis a perceived other. In this paper, I will look at Friedrich Nietzsche’s atheism from the perspective of Dōgen’s philosophical standpoint. Concretely, I will present Nietzsche’s position on his own terms, translate his philosophy into Dōgen’s terminology, interpret his philosophy from the standpoint of Dōgen’s philosophical approach, and assess the utility of such an exercise. I believe that such a project enables us to read theism through the eyes of atheism, atheism through the eyes of theism, both through the eyes of Dōgen, and Dōgen through the eyes of the a/theism debate. In this last section, I will introduce the language of Nishida Kitarō who attempted a similar project in his The Logic of Basho and the Religious Worldview. The goal of this project is to determine what atheism denies, what atheism contributes, and why a multi-faceted and multi-cultural engagement of atheism is important today. (shrink)
