Both this article and the book reviewed are pretty pallid stuff. It amazes me that people who dare to write on such an important topic assume they can do so intelligently with no knowledge of the history of philosophy, theology, and comparative religion. They apparently have not read Theosophy, which pioneered the notion of spiritual evolution through H. P. Blavatsky and her many disciples, nor Sri Aurobindo, who followed up this path brilliantly and was thoroughly acquainted with Darwinism, nor Teilhard de Chardin who attempted with great insight to reconcile scientific evolution with Christian understanding. This has not been a new subject for two hundred years; indeed Hegel in the time of Napoleon made human spiritual evolution the basis of his historical dialectic. It is sad that the pallid scientism of the current generation is unacquainted with all these rich texts which could color, extend, and enliven it (if not make it utterly pointless).
