Wittgenstein famously asked: What is left when we subtract the fact that my arm rises from the fact that I raise it?

The readiest answer—that causation by an intention is the missing element—is oversimple. Intentionality, however, may be crucial even if intentions alone cannot provide an answer. Elizabeth Anscombe apparently favored reasons for acting; but reasons in the abstract, say as true propositions,…

Wilson characterizes weak and strong emergence partly based on their differing solutions to the exclusion problem. The weak emergentist should claim that emergent phenomena and their bases can both cause the same effect without overdetermining it, because they literally share causal powers. I compare this strategy with a different but related strategy also available to the weak emergentist, and argue that the virtues of the former cost more than it appears.
