Kirkpatrick's contribution is evaluated in the context of historical developments and persistent crisis in the psychology of religion. The field has been characterized by the lack of a unifying theory, as well as by some literature being driven by religious apologetics. Kirkpatrick's approach has been truly theory-driven, always seeking a general psychological framework for analyzing religion and religiosity. His personal odyssey led him to embrace Bowlby's attachment theory, which has had a unique impact of research in academic psychology. But then Kirkpatrick demonstrates his honesty and courage in realizing that the attachment framework was less than adequate for the task of unifying the field. Instead, he invites us to join him in embracing the broader framework of cognitive-evolutionary theory, which should serve as the unifying framework for the field. I concur with his judgment.
