Causal Non-Symmetry
Causation is a non-symmetric rather than asymmetric relation. Different bases of causal non-symmetry include an asymmetry of overdetermination, the independence condition, and agency. Causal non-symmetry can be rooted in one or more of these three while also recognizing a fourth non-symmetry appealing to a primitive non-symmetric chance-raising. Each counts as an appropriate basis for causal non-symmetry because it is a (partial) realization of non-symmetric chance-raising. Key moves involve a refinement of how to understand the way in which the asymmetry of overdetermination works, and how it interacts with the revised similarity weighting, the contribution of the independence condition to a proper understanding of the transition period, the role that appeals to primitive non-symmetric chance-raising should play in the treatment of problem cases, the circumstances in which an appeal to an interlevel non-symmetry of agency may be appropriate, and the priority ordering of these various realizations of causal non-symmetry.
