Context: Ought I to say that the form of change is fixity, or more precisely, that change is an endless search for fixity? A nostalgia for inertia: indolence and its frozen paradises. Wisdom lies neither in fixity nor in change, but in the dialectic between the two. A constant coming and going: wisdom lies in the momentary. It is transition. But the moment I say transition, the spell is broken. Transition is not wisdom, but a simple going toward… Transition vanishes: only thus is it transition.
“Not to be absolutely certain is, I think, one of the essential things in rationality.”
