The Lost Light: An Interpretation of Ancient Scriptures (1940) by Alvin Boyd Kuhn argues that religious texts, especially the Bible, are not literal history but allegorical, esoteric works derived from ancient Egyptian theology. Kuhn contends that misinterpreting these allegories as historical facts obscured profound spiritual truths regarding the soul’s evolution. Kuhn’s thesis is that turning the "mistaken" literal view into a deeper, symbolic understanding can revitalize modern religion and spirituality.
