Participatory Spirituality for the 21st Century
You can see right off that several "zones" are represented in these definitions. An Integral definition, or series of definitions, would include even more zone-perspectives, and IMP may suggest ways these various types of "states" can be correlated. But simple differentiation of zone-specific definitions will also be important, since I believe the failure to do this probably contributes not infrequently to conflicts and misunderstandings in Integral discussions.
As we discussed in an earlier series of threads (The Status of States), Wilber's use of certain states (particularly causal and nondual) seems still to involve certain metaphysical commitments, which we critiqued at length. But I don't recall that we really arrived at any workable, formal definition of states, or understanding of what is involved in "state training" and "state stabilization" in spiritual development or "realization," so I'd like to return to this question here, if you're interested.
One systems-theoretic, naturalistic definition of states has been attempted by Charles Tart:
"Now I shall formally define a discrete state of consciousness (d-SoC) for a given individual (and I emphasize for a given individual) as a unique configuration or system of psychological structures or subsystems. The structures or subsystems show some quantitative and minor qualitative variation in the way in which they process information or cope or have experiences, but the structures or subsystems and their energetic pattern of interactions comprise a 'system'. The operations of the components, the psychological structures,interact with each other and stabilize each other's functioning by means of feedback control such that the system, the discrete state of consciousness, maintains its overall patterning of functioning within a varying environment. That is, the parts of the system that comprise a discrete state of consciousness may vary over various ranges if we look at individual components, but the overall, general configuration, the overall pattern of the system remains recognizably the same. As an analogy, you can drive your car faster or slower, with a varying number of passengers in it, or change the color of the seat covers, but it retains its identity as the system we know as an automobile. So one may have variations in consciousness, such as being more or less activated, more or less aware of the environment, etc. that represent quantitative changes in certain subsystems or structures of the system, but they do not change the overall, recognizable configuration of the system as being that of our ordinary [waking] state of consciousness, or, for that matter, of any particular discrete state of consciousness. The way to understand a discrete state of consciousness, then, is not only to investigate the structure of the parts in a more and more molecular way, but also to be aware of the way in which the parts interact and the 'gestalt' system-properties of the configuration that arise that may not be predictable from a knowledge of the parts alone." (Tart, THE BASIC NATURE OF ALTERED STATES OF CONSCIOUSNESS: A SYSTEMS APPROACH)
One question that I bring to this (among many) is whether we can define states postmetaphysically, but in a way that still respects and accounts for the "profundity" and power of certain state realizations -- that still can serve, in a sense, as a horizon of aspiration, without the metaphysical trappings.
I'm exploring a few thoughts in relation to this question and will post more on that soon. In the meantime, I just wanted to post this initial question and get the feedback of other members here, if you're interested.
