Religious naturalism (RN) combines a naturalist worldview with perceptions and values commonly associated with religions. In this “religious” is understood in general terms, separate from established traditions, in designating feelings and concerns (e.g. gratitude, wonder, humility, compassion) that are often described as spiritual or religious and “naturalism” refers to a view that the natural world is all we have substantiated reason to believe exists and there is no substantiated reason to believe that anything else, including deities, exists or may act in ways that are independent of the natural order.
Areas of inquiry include attempts to understand the natural world and the spiritual and moral implications of naturalist views. Understanding is based in knowledge obtained through scientific inquiry and insights from the humanities and the arts. Religious naturalists use these perspectives in responding to personal and social challenges (e.g. finding purpose, seeking justice, coming to terms with mortality) and in relating to the natural world.
Naturalism is the "idea or belief that only natural (as opposed to supernatural or spiritual) laws and forces operate in the world."
All forms of religious naturalism, being naturalistic in their basic beliefs, assert that the natural world is the center of our most significant experiences and understandings. Consequently, nature is considered as the ultimate value in assessing one's being. Religious naturalists, despite having followed differing cultural and individual paths, affirm the human need for meaning and value in their lives. They draw on two fundamental convictions in those quests: the sense of Nature's richness, spectacular complexity, and fertility, and the recognition that Nature is the only realm in which people live out their lives. Humans are considered interconnected parts of Nature.
Science is a fundamental, indispensable component of the paradigm of religious naturalism. It relies on mainstream science to reinforce religious and spiritual perspectives. Science is the primary interpretive tool for religious naturalism, because, scientific methods are thought to provide the most reliable understanding of Nature and the world, including human nature.
