-
- It also comes perilously close to tautology, whether you are a PCT proponent
- or not. To have purposeful behaviour is to have a purpose or goal, with
- behaviour calculated to lead toward achievement of that goal. And how can
- that achievement or progress toward it be assessed other than by perception
- (in the broad sense in which you intend the term)? Even in PCT terms, the
- word "control" cannot be limited to smooth or monotonic results of monotonically
- directed actions--things break abruptly after smoothly increased forces are
- appied, for example. The breaking may be the achievement of the goal, or
- a step toward it, or an unwanted step away from it. So it is not clear to
- me what that slogan achieves, except to make people think about the importance
- of the feedback loop.

-
- They aren't even in the same domain, so I don't see how they could "look" the
- same. Exploration involves some observable actions, reorganization is
- totally internal, even though it may strongly affect subsequently observed
- actions. I think of exploration as a means toward safe reorganization
- (performed at zero gain), not as a form of reorganization.
