Book excerpt: This book elaborates the author's original metaphysics, panenmentalism, focusing on novel aspects of the singularity of any person. Among these aspects, integrated in a systematic view, are: love and singularity; private, intersubjective, and public accessibility; multiple personality; freedom of will; akrasia; a way out of the empiricist-rationalist conundrum; the possibility of God; and some major moral questions.
