"Integral Spirituality" answers the question: how can we validate the existence of spiritual realities - specifically, the higher levels of mystical experience claimed by the world's wisdom traditions - in the face of modern and postmodern attacks that deny those realities as unscientific or reduce them to social constructions?Applying his highly acclaimed integral approach, Wilber formulates a theory of spirituality that honours the truths of modernity and postmodernity - including the revolutions in science and culture - while incorporating the legacy of the great religions. He shows why full enlightenment is not possible without combining the enlightenment of the East, which excels at cultivating higher states of consciousness, with the enlightenment of the West, which offers developmental and psychodynamic psychology. Each contributes key components to a more integral spirituality. On the basis of this theoretical framework, Wilber is able to make some timely suggestions. Because the world's religions have such a tremendous influence on the worldview of the majority of the earth's population, they are in a privileged position to address some of the biggest conflicts we face.By adopting a more integral view, and thus effectively responding to contemporary critiques, the great religions can act as facilitators of human development, from mythic belief to rational science to postmodern pluralism - all the way up to enlightenment, and to a global society that honours and includes all the stations of life along the way. This is a vital book for our times.
