 Alan Donagan (1977) suggests a similar account of the distinction. To determine whether the agent is positively or negatively relevant to an upshot, we should consider what would have happened if the agent had not acted at the relevant moment, or what would have happened if the agent had ‘abstained from intervening in the course of nature’. It isn’t entirely clear what we are supposed to imagine when we imagine this but perhaps it’s that the agent is asleep or in a trance or in some other way unable to exercise her agency. Now—with respect to some behavior that led to some upshot, we might ask: would that upshot have occurred if the agent had abstained from intervening in the course of nature? If it would have, the agent allowed the upshot. If it would not have, then she did it (her relevance to the upshot is positive).
