Human freedom resides primarily in exercise of that capacity that humans employ more abundantly than any other species on earth: the capacity for judgement. And in particular: that special judgement in relation to Self that we call aspiration. Freedom is not the absence of a field of (other) powers; instead, freedom shows up only against the reticulations of power impinging from without. For freedom worthy of the name must be construed as an exercise of power within an already-present field of power. Thus, liberty and causal necessity are not obverses.
