It seems that one of the greatest advantages we have as humans is the ability to question ourselves—to test our own position for validity and strength, to continually refine and sharpen it, or abandon it altogether in favor of a stronger stance. We don’t need to be purely reactive, as most animals seem to be. We can be driven by something other than pain, or the harsh forces of evolution.
This assertion requires the existence of free will. If such a thing exists, then it seems to be wasted in many cases; most people seem to only be willing to change in the face of extreme pain.
I think this might be the essence of strategy, only extrapolated onto an existential scale.
