All the ideas in this book are illustrated by scientific studies and personal experiences of the author. The latter gives, among other things, MBSR training for years, allowing it to have much perspective on what people look, their illusions and remedies to dispel. This is not just a writer or a scientist who wrote this book, but an explorer of Happiness and Emotional Intelligence: He knows whereof he speaks and allows us to discover what he himself discovered during all those years of studies and personal experiences.
A book very inspiring that I highly recommend. For me, this "Praise of Lucidity" is so rich and dense that it will remain my bedside book for several months to come back regularly.
