I purchased this book at a library book sale thinking it was Eric Voegelin, not Robert Fogelin. I only learned, never to judge a book by the last name.
The thesis of the book rests on Kant's famous preface to his Critique of Pure Reason. It deserves to be quoted at length, really anywhere.
"Human reason has this peculiar fate that in one species of its knowledge it is burdened by questions which, as prescribed by the very nature of reason itself, it is not able to ignore, but which, as transcending all its powers, it is also not able to answer.
The perplexity into which it thus falls is not due to any fault of its own. It begins with principles which it has no option save to employ in the course of experience, and which this experience at the same time abundantly justifies it in using. Rising with their aid (since it is determined to this also by its own nature) to ever higher, ever more remote, conditions, it soon becomes aware that in this way—the questions never ceasing—its work must always remain incomplete; and it therefore finds itself compelled to resort to principles which overstep all possible empirical employment, and which yet seem so unobjectionable that even ordinary consciousness readily accepts them. But by this procedure human reason precipitates itself into darkness and contradictions."
In short, although the quote above is already Kant's 800 pages of epistemology in short, the basic thought is that our concepts and thoughts often go on a logical journey of their own unrestricted by any concrete experience that puts us in a very depressed mood. "Percepts without concepts are blind"—mere experience without any preconceptions to categorize and bind experiences into a coherent representation is blind. "Concepts without percepts are empty"—mere thoughts without experience to limit and restrict endless chains of thoughts that lead to abyss of absurdity are personally meaningless. So the enterprise of knowing is far from a mere passive phenomena of preordained stimuli impressing themselves upon the "tabula rasa" of the human mind, but it is rather an active intuitive process of conscious selection and organization of the scattered phenomena of the world.
Fogelin, relating to his expertise in philosophical skepticism and especially Wittgenstein, explains the very obvious tension that the lengthy quote above prefaces. The human project called knowledge inevitably appears more and more arbitrary the more we admit human intuitive categories of perceptions or whatnot into our realm of facts. How do we justify the increasingly arbitrary nature of knowledge with our inherent hunger for pure facts? This is not just an abstractly esoteric dilemma. It is a “human dilemma.”
Fogelin offers examples. Recall the famous liar paradox, one of whose many versions go something like “I always lie.” Let’s call this statement “X.” The problem is apparent. If I am in fact lying while stating X, then I am in fact telling the truth by virtue of the meaning of X. So X is false. Then, if I am not lying while stating X, then I am in fact telling the truth by virtue of the meaning of X. So X is false in both cases. This is an inherently linguistic paradox that arises as a product of our attempt to rationalize the world by imposing our linguistic structures upon hypothetical situations. Does this mean, because we’ve found an error in our system that seems logically permanent and permanently logical, we should abandon our language? How can we expect to have meaningful discussions about truth when the very linguistic vehicle of thought itself is flawed?
Another example of dilemma by Fogelin. We all know moral situations in which we cannot not possibly choose one situation over another simply by innate laws of human reason. Fogelin give Satre’s well-known example of the son who is torn between staying with his aging mother and going to battle to fight for his country. So, again, the question rises: what are we to do with this moral system (putting aside any inputs from divinity, of course) that innately presents us with illogical qualms?
Okay, one more example. Are you certain that you are biologically related to your mother? Because your relatives have told you? Because you have photos or your birth certificate? But since when has your criteria for certainty dropped so low as to believe second-hand experience! However, you know it is simply impossible to empirically find out the truth of this situation. To be perfectly consistent with your skepticism, you must be suspicious of your mother’s embrace and never really trust her. However, no one is willing to do this. It makes sense, but also absurd.
Fogelin’s answer is balance. “It is essential to see that an irreconcilable moral conflict can exist without bringing all morality down around it” (61). Because human rationality pivots around our categories of understanding which our mind imposes on the world of scattered phenomena, not everything will be perfect as long as mankind is imperfect. So as we run into components of the world that we find incompatible with our developed faculties of reason, such as Kant’s antinomies or irreducible moral dilemmas, questions of free will versus naturalism, etc., we must remember that the goal in life is not to test our reason with further abstract concepts for the sake of empty certainty in valiant skepticism but simply to use reason as a torch with which we journey through our labyrinth of raw experience. Not to fear the imminent fragility of reason, “because the moves that lead to it, though… [logical], are wholly unmotivated” (46). If we are motivated for the right reasons of living, we cannot let the empty ghosts of reason frighten us to forever turn our eyes inward away from the world into a dark solipsistic universe.
“We seem to live our intellectual lives on the edge of absurdity” (95). If we truly embrace our heritage of reason which comes down to us through the radical skepticisms of Berkeley, Hume, and others, we realize that “scepticism is not irrefutable, but obviously nonsensical” (107). At the end, our own will play a larger role in maintaining our sanity than we would like to admit in this intellectual sphere so dominated by western absolutist thinking. Although Fogelin does not seem to be so fond of the “over-reactions” of postmodernist thinkers such as Kuhn or some critical theorists, he poses a much needed question. That is, how will we react individually. I revere Schopenhauer’s confession that the world is his will. We all are walking this tightrope of reason. Beneath us awaits an ocean of certainty into which our unrestrained reason calls us to plunge into. We can free ourselves of these shackles of doubts, but only to swim helplessly in freedom without a sense of direction, for we will have lost the capacity to love, to desire, to strive for anything, for living requires a commitment called faith. Or we continue to walk the tightrope of reason, living on the edge of absurdity, where the only guard-rail is our will to live, love for life.
There are many quotes from Hume in this book. I will end with this one.
“In general, there is a degree of doubt, and caution, and modesty, which, in all kinds of scrutiny and decision, ought for ever to accompany a just reasoner.”
