James Boswell wrote this in his journal on Monday, 22 October, 1781:
Walked to Craighouse and breakfasted with Lord Covington, whom I had not seen for many months. He was grown very dull of hearing, and gave me a discouraging view of life and old age and human existence. He said his memory was failed, and that the mind and body failed together; and he seemed to acquiesce in that dreary notion, without hope of restoration. And he said when one looked back on life, it was just a chaos of nothing.
