“When Goldsmith said, ‘We have a claim upon you,’ Johnson replied, ‘I am not obliged to do any more. No man is obliged to do as much as he can do. A man is to have part of his life to himself.’ Though he is quite justified, he is plainly uneasy in his own conscience as he continues to rationalize; and when Boswell, instead of dropping the matter, says, ‘I wonder, Sir, you have not more pleasure in writing,’ there is the testy response: ‘Sir, you may wonder.'”
W. Jackson Bate, Samuel Johnson
