"Writing about the middle of the eighteenth century, David Hume proclaimed John Napier of Merchiston as 'the person to whom the title of a great man is more justly due than to any other whom his country ever produced.' This judgment of Hume is the more remarkable, seeing he was himself naturally disposed to exalt literature above science. ...when he awarded the first place among his countrymen to Napier... it was doubtless from an enlivened conviction that his work had been of greater service to humanity."
