Through the analyses of responses to attacks to September 11, the authors interpret trauma as a catalyst of transformation of cultural consciousness and American self, and articulate the foundations for a transpersonal theory of cultural evolution. Accounts feature positive values, humanistic and spiritual aspirations, direct intuition of the evolution of consciousness, and the instances of new type of integral consciousness identified with both oneness and multiplicity. Authors use the theory of emergent evolution of Sri Aurobindo and Gebser, and the spiritual psychology of Ibn-Arabi, as opposed to positivist and critical theory evolutionary perspectives. Imaginative responses to complexity and trauma, refocusing attention on spiritual values, and transpersonal dialog are indicated as components of the new cultural strategies.Focusing on transformative experiences that have emerged out of the trauma and conflict of September 11 (9/11), we find signs of a cultural transformation of consciousness and propose to articulate the foundations for a transpersonal theory of cultural evolution. In emphasizing instances of integral consciousness and the spiritual aspects of responses to 9/11, we are not devaluing mourning, fear, anger, or the national pain of loss. However, as researchers we cannot deny the evidence of another class of phenomena in the aftermath of 9/11, such as complex spiritual, imaginative and transformative. These experiences can also be described as transpersonal, sacred, altruistic, and positive.
