Plantinga's argument is aimed at metaphysical naturalism or roughly the view that no supernatural beings exist. Naturalism is typically conjoined with evolution as an explanation of the existence and diversity of life. Plantinga's claim is that one who holds to the truth of both naturalism and evolution is irrational in doing so. More specifically, because the probability that unguided evolution would have produced reliable cognitive faculties is either low or inscrutable, one who holds both naturalism and evolution acquires a "defeater" for every belief he/she holds, including the beliefs associated with naturalism and evolution.

This is a collection of essays on the history and philosophy of evolutionary biology by the well-known Canadian scholar, Michael Ruse. Much has been written newly for the collection, as the author explores themes of evolutionary naturalism, putting the theory of knowledge and of moral behaviour on a philosophical basis informed by contemporary evolutionary biology. Divided into three parts, the first set of essays considers issues in the history of science - Darwin, population biology, and the new paleontological theory of `punctuated equilibria' - attempting to find a path between the crude objectivity espoused by many working scientists, and the rank relativism of post-modernist critiques of science. The second set of essays turns directly to the theory of knowledge (epistemology), arguing that the fact that we are evolved beings rather than objects of special creation, must and does inform our thinking about the external world. The third set of essays, the most controversial, turns to questions of morality, arguing that ethical systems are ultimately no more than collective illusions put in place by our biology, because humans are essentially social animals. Written in a clear and non-technical fashion, this collection carries forward debate on a number of controversial issues, showing that the time has now come to take philosophy from the hands of academic theorists and to embrace fully the findings and consequences of modern science.

Scholars have tended to portray T.H. Huxley, John Tyndall, and their allies as the dominant cultural authority in the second half of the 19th century. Defenders of Darwin and his theory of evolution, these men of science are often seen as a potent force for the secularization of British intellectual and social life. In this collection of essays Bernard Lightman argues that historians have exaggerated the power of scientific naturalism to undermine the role of religion in middle and late-Victorian Britain. The essays deal with the evolutionary naturalists, especially the biologist Thomas Henry Huxley, the physicist John Tyndall, and the philosopher of evolution, Herbert Spencer. But they look also at those who criticized this influential group of elite intellectuals, including aristocratic spokesman A. J Balfour, the novelist Samuel Butler, and the popularizer of science Frank Buckland. Focusing on the theme of the limitations of the cultural power of evolutionary naturalism, the volume points to the enduring strength of religion in Britain in the latter half of the 19th century.

"Tilman argues that evolutionary naturalism provides the philosophical foundations of Veblen's thought. He links evolutionary naturalism to Veblen's aesthetics, secular humanism, sociology of control, sociobiology, and sociology of knowledge, thereby initiating observations regarding the relationship of Veblen's own life to his thinking and his place as a cultural lag theorist"--Provided by publisher.
