many phenomena (including altruism) that gene-based selection cannot satisfactorily explain. The philosopher Mary Midgley, with whom Dawkins clashed in print concerning The Selfish Gene, has criticised gene selection, memetics, and sociobiology as being excessively reductionist; she has suggested that the popularity of Dawkins's work is due to factors in the Zeitgeist such as the increased individualism of the Thatcher/Reagan decades. Besides, other, more recent views and analysis on his popular science works also exist. In a set of controversies over the mechanisms and interpretation of evolution (what has been called 'The Darwin Wars'), one faction is often named after Dawkins, while the other faction is named after the American palaeontologist Stephen Jay Gould, reflecting the pre-eminence of each as a populariser of the pertinent ideas. In particular, Dawkins and Gould have been prominent commentators in the controversy over sociobiology and evolutionary psychology, with Dawkins generally approving and Gould generally being critical. A typical example of Dawkins's position is his scathing review of Not in Our Genes by Steven Rose, Leon J. Kamin, and Richard C. Lewontin. Two other thinkers who are often considered to be allied with Dawkins on the subject are Steven Pinker and Daniel Dennett; Dennett has promoted a gene-centred view of evolution and defended reductionism in biology. Despite their academic disagreements, Dawkins and Gould did not have a hostile personal relationship, and Dawkins dedicated a large portion of his 2003 book A Devil's Chaplain posthumously to Gould, who had died the previous year. When asked if Darwinism informs his everyday apprehension of life, Dawkins says, "In one way it does. My eyes are constantly wide open to the extraordinary fact of existence. Not just human existence but the existence of life and how this breathtakingly powerful process, which is natural selection, has managed to take the very simple facts of physics and chemistry and build them up to redwood trees and humans. That's never far from my thoughts, that sense of amazement. On the other hand, I certainly don't allow Darwinism to influence my feelings about human social life," implying that he feels that individual human beings can opt out of the survival machine of Darwinism since they are freed by the consciousness of self. "Meme" as behavioural concept In his book The Selfish Gene, Dawkins coined the word meme (the behavioural equivalent of a gene) as a way to encourage readers to think about how Darwinian
