As we continue to consider the various arguments for God's existence based upon Peter Kreeft's Twenty Arguments God's Existence, this week we look at an argument from consciousness.
Kreeft writes:
When we experience the tremendous order and intelligibility in the universe, we are experiencing something intelligence can grasp. Intelligence is part of what we find in the world. But this universe is not itself intellectually aware. As great as the forces of nature are, they do not know themselves. Yet we know them and ourselves. These remarkable facts—the presence of intelligence amidst unconscious material processes, and the conformity of those processes to the structure of conscious intelligence—have given rise to a variation on the first argument for design.
1. We experience the universe as intelligible. This intelligibility means that the universe is graspable by intelligence.
3. Not blind chance.
4. Therefore this intelligible universe and the finite minds so well suited to grasp it are the products of intelligence.
There are obvious similarities here to the design argument, and many of the things we said to defend that argument could be used to defend this one too. For now we want to focus our attention on step 3.
Readers familiar with C. S. Lewis's Miracles will remember the powerful argument he made in chapter three against what he called "naturalism": the view that everything—including our thinking and judging—belongs to one vast interlocking system of physical causes and effects. If naturalism is true, Lewis argued, then it seems to leave us with no reason for believing it to be true; for all judgments would equally and ultimately be the result of non-rational forces.
Now this line of reflection has an obvious bearing on step 3. What we mean by "blind chance" is the way physical nature must ultimately operate if "naturalism" is true—void of any rational plan or guiding purpose. So if Lewis's argument is a good one, then step 3 stands: blind chance cannot be the source of our intelligence.
We were tempted, when preparing this section, to quote the entire third chapter of Miracles. This sort of argument is not original to Lewis, but we have never read a better statement of it than his, and we urge you to consult it. But we have found a compelling, and admirably succinct version (written almost twenty years before Miracles) in H. W. B. Joseph's Some Problems in Ethics (Oxford University Press, 1931). Joseph was an Oxford don, senior to Lewis, with whose writings Lewis was certainly familiar. And undoubtedly this statement of the argument influenced Lewis's later, more elaborate version.
If thought is laryngeal motion, how should any one think more truly than the wind blows? All movements of bodies are equally necessary, but they cannot be discriminated as true and false. It seems as nonsensical to call a movement true as a flavour purple or a sound avaricious. But what is obvious when thought is said to be a certain bodily movement seems equally to follow from its being the effect of one. Thought called knowledge and thought called error are both necessary results of states of brain. These states are necessary results of other bodily states. All the bodily states are equally real, and so are the different thoughts; but by what right can I hold that my thought is knowledge of what is real in bodies? For to hold so is but another thought, an effect of real bodily movements like the rest. . . These arguments, however, of mine, if the principles of scientific [naturalism]... are to stand unchallenged, are themselves no more than happenings in a mind, results of bodily movements; that you or I think them sound, or think them unsound, is but another such happening; that we think them no more than another such happening is itself but yet another such. And it may be said of any ground on which we may attempt to stand as true, Labitur et labetur in omne volubilis aevum ["It flows and will flow swirling on forever" (Horace, Epistles, I, 2, 43)]. (Some Problems in Ethics, pp. 14—15)
