Abstract
Many of the sciences (including economics) have been dominated by a naturalist worldview that generally assumes that the universe and life are purposeless and that mankind is simply a more complex, material version of everything else in the natural world. The renowned scholar and author C. S. Lewis offers an important link with the work of economists who have seen scholars' embrace of positivism and scientism as contrary to the development of knowledge regarding human action. In examining naturalism, Lewis shows that material "facts" alone cannot provide any conclusions without some independent basis to evaluate such data. He claims that the analysis of any world requires the existence of scientists whose views are not mechanically determined by the world they are examining. In so doing, Lewis clearly understands that reason, free will, and individual choice are not illusions; they are intrinsic and objective truths--nonnegotiable presuppositions--upon which human inquiry and economic science rest. Such understanding necessitates a theistic dualism of both a material and immaterial, natural and supernatural, physical and metaphysical reality.
I. Introduction
For many years, the natural and social sciences (including economics) have been dominated by the naturalist worldview that the universe and life are purposeless and that humankind is simply a more complex version of everything else in the material world. In other words, an individual human is no more and no less than a system of molecular processes determined by physical laws. In this system, all human endeavors and ideas are the product of a mechanistic, causal process of physical events.
Although probably best known for his fiction, Oxbridge University scholar C. S. Lewis also examines the naturalist worldview and makes the case that material "facts" alone cannot provide any conclusions without some independent basis to evaluate such data. He claims that the analysis of any world requires the existence of scientists whose views are not themselves mechanically determined by the world being examined. Lewis presents the "argument from reason" that the enterprise of science cannot exist if a strictly naturalist view of science were true. He maintains that efforts to apply a naturalist theory to knowledge, including economic science, lead to a denial of the validity of reasoning and the notion of truth. In this paper, I argue that C. S. Lewis should be recognized as making an important contribution to our understanding of the foundations of the natural and social sciences, including economics. Using Lewis's analysis as a starting point, I argue that for reason, free will, and science to be possible, a worldview based on a dualist theism is required. Moreover, I argue that such a perspective needed to be widely adopted before all sciences, including economics, could be established. In the process, I contrast science with scientism; discuss how science arose from the Christian theist worldview, as opposed to other religions; link Christian thought with the central insight of methodological individualism and the rise of intellectual and social movements for liberty and the abolition of slavery; examine how Lewis's "argument from reason" refutes naturalism as self-contradictory; demonstrate how naturalism fails in its abolition of the self; and, in the process, show why dualist theism is necessarily true.
II. Science Versus Scientism
The naturalist (modernist, structuralist) worldview posits that all of reality is defined in terms of the natural or material world and that no parallel or extranatural or supernatural world exists apart from this natural world. As Lewis notes,
[T]he Naturalist thinks that nothing but Nature exists, the word Nature means to him merely "everything" or "the whole show" or "whatever there is." ... What the Naturalist believes is that the ultimate fact, the thing you can't go behind, is a vast process in space and time which is going on of its own accord. Inside that total system every particular event ... happens because some other event has happened; in the long run, because the Total Event is happening. Each particular thing ... is what it is because other things are what they are; and so, eventually, because the whole system is what it is. All the things and events are so completely interlocked that no one of them can claim the slightest independence from "the whole show." None of them exists "on its own" or "goes on of its own accord" except in the sense that it exhibits, at some particular place and time, that general "existence on its own" or "behavior of its own accord" which belongs to "Nature" (the great interlocked event) as a whole. (2001b, p.6-8, emphasis in original)
Lewis then notes the naturalist's determinist dilemma regarding the existence of individual free will, including the naturalist's own ability to argue for naturalism or any proposition: "Thus no thoroughgoing Naturalist believes in free will: free will would mean that human beings have the power of independent action, the power of doing something more or other than what was involved by the total series of events. And any such separate power or originating events is what the Naturalist denies. Spontaneity, originality, action 'on its own,' is a privilege reserved for 'the whole show,' which he calls Nature." (2001b, p.8, emphasis in original).
Naturalism as a creed is a very old one. A number of the pre-Socratic philosophers (e.g., Thales, Empedocles, Anaxagoras, and Democritus) were probably the first to propose an early version of naturalism. Plato, Paramenides, and Aristotle discredited the pre-Socratic naturalists, however, and it was not until much later that the naturalist creed resurfaced in a major way in the eighteenth and nineteenth centuries, based on the work of David Hume, Auguste Comte, Henri de Saint-Simon, Friedrich Nietzsche, Karl Marx, Sigmund Freud, Charles Darwin, and others (Markos, 2003, p.32). With this worldview, Nietzsche logically proposed that man "is beyond good and evil," and behaviorist-naturalist B. F. Skinner claimed that man is "beyond freedom and dignity."
Of course, one may make the objection that Lewis overgeneralizes; some naturalists do not consider themselves to be strict materialists or physicalists. And some nonphysicalist naturalists, such as Buddhists, claim that matter itself ultimately is not basic to a reality, which they still define entirely by the universe--a...
