 The story has been very widely cited and his four-step account of how one arrives at novel ideas has been adopted by those presenting the development of creative ideas in analogy with Darwinian blind variation, such as Donald Campbell (1987 [1960]: 99–100) and Dean K. Simonton (1988: 27–33; 1995: 468–86; 1999: 32–4); see Kronfeldner for a critical survey of the literature (2011: esp. 64–65). Poincaré’s creativity has also been analyzed and compared to that of other scientists, especially Einstein, by Arthur Miller (1984, 1992, 1996b, 1997).
