Heraclitus pointed out that we cannot step in the 'same' river twice. However, the 'sameness' that does persist through the ongoing flow of water is one image of a dissipative structure. The concepts of state psychology, looked at as complementary to process, take on a different feel. This is more than just a logical postulate - character can throw up some very rigid limits, which we can often benefit from challenging in ourselves. But even the most rigid limits, I am arguing, are most usefully understood as moves in the game of incarnation - as eccentric, 'characterful' ways of being someone.
Life is a trade-off between stability and change, state and process.
We can shift the balance around between the two, but we cannot choose one and not the other - not if we want to stay embodied.
