 Suppose that a day spent in Heaven has utility 1 and a day spent in Hell has utility \(-1\). Suppose further that, for all \(n\), \(n\) days in Heaven have utility \(n\), and \(n\) days in Hell have utility \(-n\). Suppose, finally, that, for all \(m\) and \(n\), any combination of \(m\) days in Heaven and \(n\) days in Hell has utility \(m - n\).
