The standard trolley problem asks whether I would divert a runaway trolley to kill one person instead of five. I used to answer yes. Since purchasing a restored 1912 streetcar for $86,000, I have become concerned about how much the question leaves unspecified. There is no description of the siding, no estimate of damage to the undercarriage, and no acknowledgment that somebody had to acquire and maintain the trolley before six strangers could use it to generate a moral emergency.
\nA friend who teaches ethics says that we can stipulate the vehicle survives either route undamaged. This is helpful, but it reveals how quickly philosophers remove other people’s interests when those interests complicate the desired conclusion. The trolley’s preservation is simply declared. My loss of control over it is ignored. We are left with an abstract object that belongs to nobody and therefore costs nobody anything to redirect. I understand why people find the problem easier under these assumptions. I found it easier before paying the invoice.
\nOwnership introduces a stakeholder who is absent from the usual arithmetic. There are five people on one track, one on the other, and a seventh person whose productive asset has been conscripted into their dispute. My friend says my interests cannot be compared with their lives. This is precisely the kind of lexical priority that consequentialists ordinarily warn against: a whole category of welfare is assigned zero weight before the calculation begins. I spent fourteen weekends stripping paint from the seating. Those weekends occurred in a conscious being.
\nThe trolley also creates value over time. I bring it to heritage events, where children can experience a form of transportation that would otherwise exist for them only in photographs. A decision that preserves four additional lives while damaging the trolley may impose small losses on thousands of future visitors. My friend calls this grotesque aggregation. Yet when the objects being aggregated are human lives, she considers counting the foundation of moral clarity. Apparently, adding is compulsory until the result begins to favor the brass fittings.
\nThere is an epistemic asymmetry as well. I know what the trolley cost, how many events it attends, and what remains to be restored. The six people are represented only by their locations. We know nothing about their future contributions or even whether they enjoy being alive. I am being asked to write off a well-documented asset in favor of several unexamined forecasts. This is not how we would ordinarily allocate scarce resources, and the fact that the forecasts are tied to the tracks should not eliminate the need for due diligence.
\nInsurance belongs in the analysis, though it does not exhaust it. An uncontrolled accident and a deliberate diversion may produce different coverage disputes, and somebody must bear that uncertainty. More broadly, I object to the emerging principle that ownership confers responsibility for every beneficial use to which an asset could be put while conferring no corresponding authority over those uses. If purchasing a trolley makes me morally subordinate to anyone who can arrange a sufficiently urgent problem in front of it, the incentive to invest in historic transportation becomes markedly weaker.
\nMy friend has proposed a third option in which the trolley can be derailed into a ditch, saving everyone at the cost of destroying it. She regards this as an easy case. I asked whether the six people would reimburse me afterward. She said that some might be unable to afford it. This is unfortunate, but it does not make the trolley less expensive. Six people who value their lives at more than the price of a trolley should, in principle, constitute a promising financing coalition. Their inability to organize one has somehow become a moral defect in me.
\nI have also asked about precedent. Suppose people discover that my property will reliably be sacrificed whenever they place themselves in sufficient danger. Even if the current six are entirely innocent, our response changes expectations for future encounters. My friend says that no one is tying himself to a railway line to obtain free access to my streetcar. This is a narrow reading of the incentive problem. Institutions can create dependency without every beneficiary consciously engineering the circumstances of his rescue.
\nThere are versions of the dilemma in which I remain willing to intervene. If the trolley belongs to the city, for example, the costs are distributed across a large tax base, and public officials have already accepted responsibilities I never agreed to assume. My friend regards the change in my answer as proof of selfishness. I regard it as evidence that institutional context matters. A man who gives identical answers before and after discovering who owns the relevant capital is not necessarily demonstrating impartiality. He may simply be refusing to update.
\nI have offered the museum a compromise. They may continue using a generic trolley in their ethics exhibit, but they should remove the photograph of mine unless the accompanying diagram includes its valuation and a description of the restoration work. Visitors can still decide that the four additional lives justify the loss. I would merely like them to reach that conclusion after looking at the actual object they are so willing to sacrifice.
