Originally published in 1919, this book was mainly written in an attempt to 'present and defend the theory that the texture of the Universe is through-and-through spiritual'. An argument is developed based around the primary nature of experience and its varying qualities and contexts. From this perspective, the text takes issue with the purely objective approaches the author perceives as being inherent in 'neo-realist' and 'logical atomist' schools of thought. Textual notes are incorporated throughout. This book will be of value to anyone with an interest in philosophical idealism and spiritualism.
