This volume presents a re-envisioning of the field of theoretical psychology and offers unique visions for its present and future from leaders of North American philosophical psychology. It contends that theoretical psychology has reached 'middle-age' and must consider new directions to renew its growth. Rooted in a range of research traditions and the intellectual biographies of its authors, it paves the way toward this necessary revitalization of the content, activities, responsibilities, and hopes of theoretical psychology. The authors situate their analyses in the context of the increasing gap between alternative and mainstream and between the discipline and the profession of psychology. They demonstrate that changes in society, culture and technology, the internationalization of the psychological humanities, and the cross-fertilization of intellectual innovations from other disciplines now afford possibilities for new orientations in theoretical psychology. The volume aims to do justice to psychological topics, human beings, and the intellectual problems that psychologists encounter, while also providing space for (meta)theoretical engagement, often neglected in the discipline. Together, the chapters in this collection make the case that a renewal of the discipline and practice of psychology is a task that is best accomplished collectively, and, despite significant disagreements, in solidarity. Thomas Teo is Professor of Psychology in the Historical, Theoretical, and Critical Studies of Psychology Program at York University, Canada. He has been active in the advancement of theoretical, critical, and historical psychology throughout his professional career. His research has been meta-psychological to provide a more reflexive understanding of the foundations, trajectories, and possibilities of human subjectivity. .
