Godel, ought, is, and Instapundit
Godel created a series of famous paradoxes designed to make your mind explode. But they boil down to ... you can't evaluate a system within a system/you need to stand outside the system. We theists have been using an argument against atheists for a long time that goes something like this: Exactly what is the source of your morality, since you cannot get to "ought" from "is". The whole thing is said better in quotes provided by Instapundit.
First, the human condition vis-a-vis morality:
Then, the devil speaks:
This is the problem of postmodern philosophy. Once they eliminated an external source of morality -- that is, "because Jesus likes it that way" -- they're caught in the Godel problem. And they know it, and still stay there. Weird, man.
First, the human condition vis-a-vis morality:
I want to believe --and so do you-- in a complete, transcendent, and immanent set of propositions about right and wrong, findable rules that authoritatively and unambiguously direct us how to live righteously. I also want to believe --and so do you-- in no such thing, but rather that we are wholly free, not only to choose for ourselves what we ought to do, but to decide for ourselves, individually and as a species, what we ought to be. What we want, Heaven help us, is simultaneously to be perfectly ruled and perfectly free, that is, at the same time to discover the right and the good and to create it.
Then, the devil speaks:
Well, well, let me not be cruel. I know at least as well as you what total separation from Him can lead to in the way of self-deception and bad lines. I tried to replace God with myself, and you tried, as He appeared unwilling to come again, to put your faith in some laughable Second Coming of Man. No hope. As long as you wanted simultaneously to make something in the world--mankind-- into the good and still reserve the right to judge its goodness, you were doomed. You were trapped in what, to save time, I might call a Gödel problem: how to validate the premises of a system from within itself. "Good," "right" and words like that are evaluations. For evaluations you need an evaluator. Either whatever the evaluator says is good is good, or you must find some superior place to stand to evaluate the evaluator. But there is no such place in the world to stand. From the world, only a man can evaluate a man, and unless some arbitrary standards are slipped into the game, all men, at this, are equal.
Or to put it another way, one more congenial, I think, to both of us, by dispensing with God we did more than just free ourselves of some intellectual anachronism. We also dispensed with the only intellectually respectable answer to the ultimate "Why is it right to do X?" It was not so very long ago that most people (and I, too) could and did answer: "It is right to do X because God says so." That answer was at least intelligible, the only one that did not depend upon mere sublunary assertion, the only one that even if it too involved the transformation of fact into value, was not for that reason insufficient. For assuming that God existed, and had commands, it was He who was evaluating our actions. He was not part of our evaluation system, nor were his evaluations subject, or even amenable, to our evaluations of them.
That does not mean, of course, that God exists, or existing, bothers to evaluate your activities. He may not, literally or figuratively, give a damn. It is just that if He does exist (whether or not He cares), as an intellectual matter your problem of normative grounding would be solved. No more would ethical imperatives consist merely of human beliefs, intuited in privacy, perhaps validated by wide sharing or whatever, but just mortal opinions nonetheless. A belief in God and His will would solve the Gödel problem and would avoid the necessary defeat visited on any attempt to validate a system from within itself.
There are, Professor Unger, not very many possibilities. In fact, there are, I think, just two. The first is that mankind is a species that doesn't mean anything at all, except to itself. There is no evaluator out there. If the species is or becomes one thing or another, or ceases to exist altogether, nothing else cares--except perhaps some other species which, mostly with joy, might register the ecological impact of man's extinction. You are what you are, and will become what you will become, and the goodness or badness of that being and becoming is for you, and you alone, to define and declare. No state of being is more authentic than any other or, just because it exists, any better. Oh, it's not so awful. If being isn't meaning, and it isn't, meaninglessness isn't nonbeing either. You and the species get to live. It's just that you have to shape your living, and its meaning, all alone.
The second possibility is that God exists, and still cares. My own opinion is that the Hand that holds you suspended over my fiery pit doesn't abhor you, but has forgotten completely that It has anything in It. But God may still care, and, if that is so, you have but one epistemological problem, to learn the will of God. If there is no God, everything is permitted; if there is a God, it's even more terrifying, because then some things are not permitted, and men have got to find out which are which. Since He has the right and power to evaluate you, but no duty to do so, you are bravely right: you must pray.
But while you try to live as best you can until His revelation, perhaps you will accept some practical advice from me. Look around you at your species, throughout time and all over the world, and see what men seem to be like. Okay? Now take this hint from what you have seen: If He exists, Me too. [Emphasis mine.]
This is the problem of postmodern philosophy. Once they eliminated an external source of morality -- that is, "because Jesus likes it that way" -- they're caught in the Godel problem. And they know it, and still stay there. Weird, man.
Those academic atheists of yore by and large would've agreed with the terms of the dilemma as stated. And they by and large would've taken the stance that there is no God, morality is an arbitrary sham, and life is meaningless above and beyond whatever arbitrary and temporary meanings you and I may cobble together.
By contrast, so many of the atheists I've read in the blogosphere these past several years seem to take the comfy, relaxed view that there is no God, everything is at root arbitrary, and yet nonetheless morality is somehow an unproblematic given. There seems to be a vague, handwaving assumption that we are hardwired by evolution for... I dunno, something that resembles a nice, suburban, upper middle class, Christian or quasi-Christian morality, though relaxed, and especially on sexual matters fairly latitudinarian. Thus the latest attempt to alchemically transmute the is of evolutionary biology into the ought of ethics.
This seems to me to be the single largest shift I've seen in "fads and fashions" among atheists over the past generation. Those academic atheists I knew were at least intellectually coherent, and willing to face up to what they saw as hard realities. While those blogospheric atheists seem to me self-deluding, to put it mildly; living in softer and more pampered times, and complacently convinced that they can have their cake and eat it too. I'd accuse them of postmodernism, but I suspect for many of them it's more like a fragrance of postmodernism wafting over the vague conviction that rationalism, scientism, and the second coming of the 18th century Enlightenment will save us.
