A Decision (n.) is never as rational as we think: we gather data, then act on a hunch, out of fatigue, or because time is up — no less a trifle than casting yarrow stalks.
Decision (n.) is free precisely because it happens: if it were voluntary we would first have to decide to decide, endlessly, and would never be free to decide at all.
A Decision (n.) is the freest of my actions, and it just happens, like hiccups inside me or a bird singing outside.
Decision (n.) still happens after liberation — but it arises of itself in relation to circumstances, not because "I" make it.
A Decision (n.) always comes with the rankling doubt that important data were overlooked, since the world can be sliced up for attention in endless ways.
