Critics have complained that "eupraxophy" is hard to pronounce, and in his later writings Kurtz has been spelling it with an extra "s," as in "eupraxsophy." But I don't see why its pronounciation with the original spelling is any harder than pronouncing "saxophone." This book is a significant contribution to our understanding and classification of worldviews, though it could benefit from a discussion of more recent eupraxophies like Objectivism and Transhumanism.
