Wilber's integral model
Explanation
Ken Wilber, an American philosopher, has developed since the 1970s one of the most ambitious theoretical projects of contemporary psychology and philosophy: the integral model. His intention is to offer a synthesis of all the great traditions of knowledge (natural sciences, social sciences, humanities, spiritual traditions) in a unified framework that respects the specific contributions of each without reducing them to one another.
The model is articulated around the AQAL scheme: "All Quadrants, All Levels". The four quadrants are the four basic perspectives from which any phenomenon can be looked at: individual interior (subjective experience, consciousness), individual exterior (behaviour, biology), collective interior (culture, shared values), collective exterior (social systems, institutions). Wilber holds that any complete theory must include the four perspectives and recognize their mutual irreducibility.
The "levels" refer to evolutionary stages of development (cognitive, moral, ego, spiritual) that Wilber synthesizes drawing on Piaget, Kohlberg, Gebser, Loevinger, Spiral Dynamics, etc. Each level transcends and includes the previous. Beyond the conventional personal levels, Wilber describes transpersonal levels (psychic, subtle, causal, non-dual), inspired by contemplative traditions, especially Vedānta and Buddhism. Complete human development includes, according to him, that spiritual trajectory.
For consciousness, the integral model proposes that consciousness has an evolutionary component (it develops through stages), a perspective component (it can look from different quadrants), and a transpersonal component (it includes states that transcend the ego). Studying consciousness requires integrating neuroscience (individual exterior quadrant), phenomenology (individual interior), cultural analysis (collective interior) and systems analysis (collective exterior). Any reduction to a single one is for Wilber a fallacy, called "absolutist quadrant".
Wilber has applied his model to various fields: psychology (An Integral Vision, The Spectrum of Consciousness), spirituality (The Atman Project), politics (A Theory of Everything), ecology, education, medicine. He has founded the Integral Institute and has generated an international community of integral practitioners. His books have been particularly influential in contemporary spiritual circles, coaching, organizational development and post-traditional spirituality movements.
Critiques are numerous. Academic: many specialists consider Wilber's syntheses to be sometimes too generalist or schematic, quickly assimilating complex phenomena to the model's pigeonholes. Philosophical: the openness to transpersonal levels and spiritual traditions is considered by many as a metaphysical commitment not scientifically justified. Communal: a certain authoritarianism in the articulation of the model has been criticized. Despite this, the integral model remains one of the most ambitious and cited syntheses in contemporary studies of human development and consciousness.
Strengths

- Calls attention to one-sided reductionisms.
- Articulates development, states and structures of consciousness.
- Influence in organizational development and education.
Main critiques
- Sometimes forced syncretism among incompatible traditions.
- Difficulty empirically validating the global model.
- Polemics about the quality of specific syntheses.
- Sometimes totalizing and self-referential tone.
