„He feared neither God, nor devil, nor man, nor wind, nor sea, nor his own conscience. And I believe he hated everybody and everything. But I think he was afraid to die. I believe I am the only man who ever stood up to him.“

—  Joseph Conrad Polish-British writer 1857 - 1924
Referring to Mr. Burns. Compare to Heart of Darkness' manager: "He was becoming confidential now, but I fancy my unresponsive attitude must have exasperated him at last, for he judged it necessary to inform me he feared neither God nor devil, let alone any mere man. I said I could see that very well..."

Attributed to her in Commons debates, 2003-07-02, column 407 http://www.parliament.the-stationery-office.co.uk/pa/cm200203/cmhansrd/vo030702/debtext/30702-10.htm and Commons debates, 2004-06-15 column 697 http://www.publications.parliament.uk/pa/cm200304/cmhansrd/vo040615/debtext/40615-20.htm#40615-20_spnew1. According to a letter http://www.telegraph.co.uk/core/Content/displayPrintable.jhtml?xml=/opinion/2006/11/02/nosplit/dt0201.xml&site=15&page=0 to the Daily Telegraph by Alistair Cooke on 2 November 2006, this sentiment originated with Loelia Ponsonby, one of the wives of 2nd Duke of Westminster who said "Anybody seen in a bus over the age of 30 has been a failure in life". <!-- He also cited Martin Gilbert's biography of Winston Churchill as a source – anyone find the appropriate page? --> In a letter http://www.telegraph.co.uk/comment/letters/3633852/Letters-to-the-Daily-Telegraph.html published the next day, also in the Daily Telegraph, Hugo Vickers claims Loelia Ponsonby admitted to him that she had borrowed it from Brian Howard. There is no solid evidence that Margaret Thatcher ever quoted this statement with approval, or indeed shared the sentiment.
