The aims of this study of Nature Mysticism, and the methods adopted for attaining them, are sufficiently described in the introductory chapter. It may be said, by way of special preface, that the nature mystic here portrayed is essentially a modern. He is assumed to have accepted the fundamentals of the hypothesis of evolution. Accordingly, his sympathy With the past is pro found: so also is his sense of the reality and con tinuity of human development, physical, psychic, and mystical. Moreover, he tries to be abreast of the latest critical and scientific conclusions. Im perfections manifold will be discovered in the pages that follow; but the author asks that a percentage of them may be attributed to the difficulties of writing in Tasmania and publishing at the antipodes.
