In the spring of 2000 a new stage in my development was reached, thanks to the learned American new-thinker Ken Wilber, especially to his magnum opus: Sex, Ecology, Spirituality (1995). Wilber takes the new science created by Prigogine and others as his starting point. But according to Wilber, not only Newton's but also Prigogine's science deals only with the external aspects of reality, and thus omits the other half of reality. Wilber wants to proceed to the levels of mind and spirit. In order to show how our world is constituted, he draws a square and divides it into four quadrants, two to the right representing the external aspect and two to the left representing the inner one. In both cases two quadrants, because Wilber also distinguishes between what is individual that is assigned to the upper quadrants and what is collective, that is assigned to the lower ones. In every quadrant he draws a diagonal from the centre and on it he indicates the levels he discerns in the world: in the external world everything from the atom to the human cerebral cortex, in the internal world from the atom's ability to react to the human "vision-logic", capable of dealing with relations, wholes, interconnections.
So the world is not a "flatland", but vertically structured in accordance with the old idea of "The Great Chain of Being". Following Arthur Koestler, Wilber calls this a "holarchy" (from the Greek holon = a whole that at the same time is part of another, higher whole). By Don Beck and others, the inner holarchy of Man has been further developed into a "Spiral Dynamics" in nine levels distinguished by different colours, to which approach Wilber has agreed (A Theory of Everything, 2000, p. 7 f).
In this way, Wilber wants to achieve what he calls "a world philosophy, an "integral philosophy", meaning a system of thoughts covering "all quadrants/all levels", and doing so in form of "orienting generalizations" about a world which thus is not disjointed and reduced to its lowest level. A philosophy which furthermore unites this new science with classical philosophy and religion in west and east into a great, all-embracing worldview.
