The two quadrants on the right concern the real, physical, material world. In a sense they are the natural domain of science. The most challenging aspect of Wilber's quadrants is discriminating between the upper and lower right quadrants. Integral expert Alan Combs helpfully explains:
The UR quadrant represents individual objects and events, while the LR represents whole collections of objects and events as well as their relationship to each other. The human brain, for example, can be seen as a single organ (UR) or as a dynamically interacting set of nerve cells and neurochemicals (LR). Both are legitimate and useful yet they represent two different perspectives. (1)
From an individual's perspective, the upper right relates to how he/she actually experiences the world through his/her five senses. So anything to do with our individual bodies (eg health) and our concrete experience of the world and our behaviour relate to this quadrant. Indeed anything about a person or thing that we can actually see belongs to the upper right quadrant. This refers, for example, to a person's skills and strengths and weaknesses as these are usually manifest in the world.
This quadrant refers to collections of events/things. This means that anything which is a 'system' belongs here such as the political, governmental, legal, health, educational systems as well as the ecosystem or planetary system. Communication networks including the mass media and the internet belong here as too does transportation and manufacturing as these are also about systems.
