"Sir, Dr Cheyne has laid down a rule to himself on this subject, which should be imprinted on every mind: 'To neglect nothing to secure my eternal peace, more than if I had been certified I should die within the day: nor to mind any thing that my secular obligations and duties demanded of me, less than if I had been ensured to live fifty years more.'"
— Boswell, James (1740-1795)
