The Costly Underwater Tunnel
An underwater tunnel is being constructed despite an almost certain loss of several lives [actually, all but certain]. Presumably the expected loss is a calculated cost that society is prepared to pay for having the tunnel ["society" doesn't make any such calculation]. At a critical moment when a fitting must be lowered into place, a workman is trapped in a section of the partly laid tunnel. If it is lowered, it will surely crush the trapped workman to death. Yet, if it is not and a time consuming rescue of the workman is attempted, the tunnel will have to be abandoned and the whole project begun anew. Two workmen have already died in the project as a result of anticipated and unavoidable conditions in the building of the tunnel. What should be done? Was it a mistake to begin the tunnel in the first place? But don't we take such risks all the time?
