"All the splendour of the highest prosperity can never enlighten the gloom with which so dreadful an idea must necessarily over-shadow the imagination; nor, in a wise and virtuous man, can all the sorrow of the most afflicting adversity ever dry up the joy which necessarily springs from the habitual and thorough conviction of the truth of the contrary system."
— Smith, Adam (1723-1790)
