This chapter situates Ian McEwan in the history of the novel of ideas, arguing that he reclaims this contested aesthetic space, producing rich and satisfying works. In doing so he pushes the boundaries of literary realism, producing a new kind of hybrid: ideational realism. The essay focuses on four novels – The Child in Time (1987), Enduring Love (1997), Saturday (2005) and Machines Like Me (2019) – a quartet of novels that illustrates the development of ideational realism throughout McEwan’s career. In these novels influential contemporary thinking is pressure-tested in the creative realm: we are invited to question the implications of science as we witness the parameters of the social novel being stretched, adjusted, and re-established. Thus, these novels represent a limited form of experimentalism, in which the significance of scientific ideas is tested, as the social relevance of realist fiction is consolidated.

Are humans superior to all other animals? People of religion – Christianity and Buddhism – say yes. People of science – those for and those against Darwinian evolutionary theory – say yes. People of philosophy – the existentialists in particular –say yes. Why? People of religion think it is God’s intention (Christians) or simply the way the world is (Buddhists). People of science, both those for and those against Darwin, think it is simply a fact of nature. People of philosophy, existentialists, argue that meaning must come from within. Are humans superior? That is for us to decide and demonstrate. Natural (science) and unnatural (religion) facts tell us nothing.

How does the organicist tackle the nature and justification of moral claims? Through the upward rise of the evolutionary process. Morality is helping it on its way to produce ever-better humans. This has been known in the past as “Social Darwinism,” and has a dreadful reputation. Supposedly, it leads straight to Hitler and the gas ovens. It cannot be denied that dreadful things have been said in the name of Darwin. Spencer wanted to drive widows and children to the wall. Andrew Carnegie was one of the worst robber barons of the late nineteenth century. Friedrich von Berhardi epitomized the worst kind of rapacious German general. But there is another side too. Spencer was in favor of free trade and virtually a pacifist. Carnegie used his fortune to found public libraries. Von Bernhardi got more from the Prussian militaristic ethic than from the Origin of Species. Hitler didn’t believe in evolution! Today, too, the story is more complex. Julian Huxley was into large-scale public works. E. O. Wilson is an ardent conservationist. The naturalistic fallacy, you cannot get ought from is, is no deterrent. Organicists do not accept that the world is value-free. Organicists and mechanist/Darwinians are in different paradigms.
