This paper argues for a ‘perennial phenomenology’ (or ‘soft’ perennialism) varying from the traditionalist notion of a ‘perennial philosophy.’ Perennial phenomenology offers a more nuanced form of perennialism that focuses on spiritual/mystical experiences rather than the teachings and beliefs of different religions. While teachings and beliefs vary greatly, the mystical experiences associated with different mystical traditions have striking commonalities. I suggest four experiential aspects that support a perennial phenomenology. These aspects also necessitate a reconsideration of the debate between perennialism and (...) constructivism. Significantly, these experiential elements are present when mystical experiences occur outside the context of spiritual traditions, to people who know little or nothing about spirituality and consider themselves non-religious. Treating mystical experiences exclusively in the context or religion and spiritual traditions has been a major failing in debates between constructivists (or contextualists) and perennialists. There is a common landscape of mystical experience that precedes interpretation and conceptualization by spiritual traditions. This paper contributes to a reopening of discussion about perennialism that has been underway in recent years. (shrink)
