Alister Hardy: A Naturalist of the Spiritual Realm

Alister Hardy was one of the pioneers of the scientific study of spiritual experiences (SE); however, his work and insights have not received the attention they deserve. This paper, based on an in-depth analysis of Hardy’s own writings, presents his main methodological and epistemological contributions for advancing the investigation of SE. Hardy’s main epistemological propositions were as follows: the transcendent as the core of spirituality and SE as a major source of R/S beliefs; a nondogmatic approach, acknowledging that Darwinian evolution does not imply materialism and that mind is not reducible to matter; and a call for studies of psychic experiences and considering an expanded naturalism, including the “para-physical”, that could lead to a perennial philosophy and a natural theology. His methods focused on phenomenological classification and the development of a natural history of SE based on studies with proper ecological validity on the experimental and the experiential, mixing large surveys of the general population with in-depth qualitative studies of the most prominent cases. In addition, it would be worth investigating developments of SE throughout a person’s life. Bringing back Hardy’s contributions will foster a better understanding of the history of the scientific study of SE and provide key insights for moving it forward.
