This book discusses spirituality as an emerging scientific topic from a historical perspective, with extensive discussion of the mind-body problem and of scientific concepts of consciousness. While the book focuses on the Western tradition of 'Enlightenment', it also implicitly addresses the double meaning of the term, with the Eastern tradition describing it as 'a state of true knowledge, which is an important goal on an individual's spiritual path' and the Western tradition seeing it as 'the collective process of getting rid of narrow-minded dogmas and concepts'. The book is based on a simple yet challenging premise: Science has not gone far enough in the scientific process of going from a collective mind tied up in dogmatic teachings to a truly free mind that, seemingly, freed itself from bondage and restrictions. The book shows that science, and with it our whole Western culture, has to incorporate spirituality if it is to realize this goal of enlightenment. If that is done, and it can only be done by many individuals actually practicing spirituality, this will also lead to the individual type of enlightenment.
