Observers in earlier epochs might have found it equally preposterous to suppose that the world economy would one day be doubling several times within a single lifespan. Yet that is the extraordinary condition we now take to be ordinary. Nick Bostrom
With respect to the present time, there are few persons who unite the qualifications of good observers with a situation favourable for accurate observation. Jean-Baptiste Say
