Abstract

An extensive data search among various types of developmental and evolutionary sequences yielded a ‘four quadrant’ model of consciousness and its development . Each of these dimensions was found to unfold in a sequence of at least a dozen major stages or levels. Combining the four quadrants with the dozen or so major levels in each quadrant yields an integral theory of consciousness that is quite comprehensive in its nature and scope. This model is used to indicate how a general synthesis and integration of twelve of the most influential schools of consciousness studies can be effected, and to highlight some of the most significant areas of future research. The conclusion is that an ‘all-quadrant, all-level’ approach is the minimum degree of sophistication that we need into order to secure anything resembling a genuinely integral theory of consciousness
