Refusing to act is a decision too, and it cannot be excused as neutrality

The argument

This argument targets the appeal to inaction on which the rival answer depends. Proponents hold that there is no neutral stance available to someone who understands the situation and can reach the lever. The bystander's choice is between two courses whose consequences they foresee, and foreseeing the consequences of leaving the trolley on its present track is not meaningfully different from intending them. Calling one option action and the other inaction describes bodily movement, not moral responsibility. Proponents argue that the distinction is in any case not honoured elsewhere. A lifeguard who watches a swimmer drown, a doctor who withholds a drug, a signalman who declines to switch the points: all are held responsible for what followed, and none is excused on the ground that they merely failed to intervene. The expectation is that a person positioned to prevent a disaster at no cost to themselves is required to do so. The trolley case puts the bystander in exactly that position, with the complication only that prevention here has a price paid by someone else. That price, proponents argue, is the whole of the problem and it is still the smaller one. Nobody disputes that diverting the trolley is a grave act or that the single death is a genuine wrong to the person who suffers it. The claim is that between two wrongs the agent must choose the lesser, and that treating one's own non-participation as a third, blameless option is a fiction. Because the bystander cannot occupy a neutral position and is responsible for the foreseen result either way, this argument concludes, they should divert the trolley and save the greater number.

Premises

Counter-arguments

Those who would spare the single man reply that conceding responsibility for inaction does not make the two responsibilities equivalent: being answerable for not intervening is a lesser charge than being the author of a death. They add that the lifeguard and doctor cases are unlike the trolley, because in those the rescue costs no third party anything, whereas here prevention requires killing someone who was safe and who consented to nothing. That is what the bystander lacks the standing to do.

Rejecting the premises

[Rejecting P1] That the bystander determines an outcome either way does not establish that both determinations are of the same kind. The objection the premise must answer is that killing and letting die differ in what the agent does, and the phrasing sets that distinction aside rather than addressing it. [Rejecting P2] The lifeguard, the doctor and the signalman each occupy a role carrying a prior duty of rescue, which is why their inaction is culpable. The bystander at the lever is defined by holding no such role, so the comparison imports the duty it was offered to demonstrate. [Rejecting C] Even granting that inaction is a choice, it does not follow that the choice must be to divert. The premises establish that the bystander cannot abstain; the conclusion that the smaller group should be sacrificed needs the further claim that only outcomes count, which is the matter in dispute.
