As both of the Right-Hand quadrants (UR and LR) are characterized by objectivity, the four quadrants are also referred to as the three value spheres of subjectivity (UL), intersubjectivity (LL), and objectivity (UR and LR). These three domains of reality are discernable in all major languages through pronouns that represent first-, second-, and third-person perspectives and are referred to by Wilber as “the Big Three:” I, We, and It/s. These three spheres can also be characterized as aesthetics, morals, and science or consciousness, culture, and nature.
Integral theory insists that you cannot understand one of these realities (any of the quadrants or the Big Three) through the lens of any of the others. For example, viewing subjective psychological realities primarily through an objective empirical lens distorts much of what is valuable about those psychological dynamics. In fact, the irreducibility of these three spheres has been recognized throughout the history of Western philosophy, from Plato’s True, Good, and Beautiful to Immanuel Kant’s famous three critiques of pure reason, judgment, and practical reason to Jürgen Habermas’ validity claims of truth, rightness, and truthfulness.
