Justification to other people › Helping someone at a modest cost

Consider a hypothetical rescue in which you can prevent a serious injury to another person at a modest inconvenience to yourself. The case is stipulated to avoid difficult questions about danger, uncertainty and competing emergencies. It illustrates a comparison of reasons rather than reporting an actual rescue or reproducing a specific case from Scanlon.

A principle allowing indifference would expose someone in the endangered person's position to a severe loss. A principle requiring assistance imposes the stipulated modest cost on the helper. These descriptions make a reason for rejecting permission visible. They also identify the objection that a requirement must answer.

The conclusion depends on the conditions. If providing assistance instead endangered the helper's life, the comparison would change. If a person repeatedly faced demands that collectively consumed their life, considering each demand in isolation might conceal the burden. The example teaches us to identify what a principle asks of a person, rather than assume that the word help settles every case.

A contractualist analysis can therefore recognize costs to the agent without making personal convenience supreme. It asks whether a proposed requirement is defensible to someone who must bear it, while also assessing the objection of the person who would otherwise be left unaided. Both positions are part of the moral inquiry.
