As you know, the Image of the Cave, which is the centerpiece of Plato’s Politeia (or Republic) is an image of human nature in chains and the story of an escape—a healing, Socrates says—from our default condition, which is one of bondage and ignorance.
There are people, though, who think that healing is what we need to be healed from, and anywhere outside the prison is what needs to be escaped. In a quite literally Orwellian “freedom is slavery” argument, I have been told that only they are truly free who are slaves, and that free men and women are enslaved—by their freedom.
This is one of those times that I will choose Socrates’ simplemindedness over the sophisticated sophistry of the sophists—I’ll go with the freedom of the mind that’s just freedom, not the sophistical freedom that is the “true freedom” of mental slavery.
But let’s take a look at this idiocy, shall we? It’s meant to “cure” me of Platonism, and since Platonism is, at bottom, the belief that reality exists and can be known, it is meant to cure me of these beliefs too. Let’s see if it succeeds, shall we?
Nine whole points. Let’s take them one at a time, shall we?
1. Plato’s essentialist, historicist and degenerative Theory of Forms or Ideas is a bad idea.
1. This is nothing more than name-calling. And it isn’t even accurate name-calling. Platonism is as anti-historicist as one can get, since to be a Platonist is to hold that there are entities and intelligible structures in reality that do not vary over time—things like mathematics or the laws of nature. It is the Caveman (as I shall call him) who is the historicist, as we will see, and who holds that human thought is incapable of rising above its historical situatedness. As for “degenerative,” the word holds no meaning here. Again, Platonism holds that there are entities and structures within reality that do not change, and being changeless, cannot degenerate. If the Cavemen is asserting there is something “degenerate” about Platonism itself, he hasn’t said what it is or even might be, so that claim can be ignored.
2. Nothing — mind, matter, self, or world — has an intrinsic or real nature.
2. Pure self-contradiction. Supposing it were true, it would be the nature of all these things not to have a nature. To be able to assert this, one would have to know that being or reality is this way—but what is being denied even as it is being asserted is that there is a way reality is. And “there is no way reality is” is just as self-contradictory an assertion as the assertion “there is no truth” (a proposition the Caveman also accepts, as we will see).
3. That does not mean that the world does not exist. The world is independent of our mental states.
3. Flat contradiction of 2. Caveman now states, in opposition to his self-contradictory principle 2, that the world does indeed have a nature, and that that nature is “to exist independently of our mental states.” Remember he said this, because his right to say this is going to be an issue.
4. It means that truth, knowledge and facts cannot exist independently of the human mind. Truth, knowledge and facts are properties of sentences, which make up larger theories and descriptions.
4. Idiotic on several levels. I am certainly willing to concede that knowledge cannot exist apart from some mind (it doesn’t have to be a human mind)—since knowledge JUST IS the apprehension of some true proposition by some mind. Notice however that Caveman in the next sentence will ridiculously ascribe knowledge not to minds, but to sentences. No, Caveman, sentences do not KNOW THINGS.
[Philosophy 101 lesson: Following the principle of charity, I’m going to take Caveman’s “sentences” to mean “propositions,” although strictly speaking he is confused. Propositions are the primary truth-bearing logical entities, and they relate to sentences in that they are expressed by sentences. Using the standard philosophical example, consider two sentences: “Snow is white” and “Schnee ist weiss”. The sentences are different. One is an English sentence and one a German sentence. The can be found in different locations on your computer screen. If they were spoken, they would be spoken at some time, in some place, by some speaker, etc. However, they both express the same proposition, which is the logical expression of the relation between a real entity, snow, and a real property of that entity, being white. That snow is white is a state of affairs in the world or a fact. The relation of snow to whiteness is an intelligible proposition which is true (the fact that snow is white makes the proposition ‘snow is white’ true). Propositions are universal. Sentences are particular. When you are I or anyone comes to know ‘snow is white’, we have the same propositional attitude towards the very same proposition, viz. that snow is white. If this were not so, we would not all know the same fact or truth about snow, but we would each ‘know’ an individual fact or truth relative to us—but the nature of knowledge is such that it is common to all. And once we have propositional knowledge we can express these propositions that we know in the linguistic entities called sentences. And it is irrelevant whether we do this by means of English, or German, or Chinese.]
As I’ve just mentioned, facts are best construed as the truth-makers of true propositions. This is because facts, as states of affairs, exist independently of their being known, that is, independently of human minds—contrary to Caveman’s assertions. It should be a fairly trivial point to note that IF Caveman is correct, we human beings produce not only the entities that may or may not be true, affirmative sentences or negations, BUT ALSO produce the truth-makers of these things, this makes FACTS and TRUTH things that are produced by human beings. We would, in this case, not only be the ones who produce claims about reality, but we would produce/create/manufacture the truth-makers that make our claims true. And this means that we human beings have the power to make any claim about anything true or false by our creative wills. Hello Nietzsche, my old friend. It’s good to meet with you again.
Finally, Caveman’s claim that truth is a property of sentences, which I will charitably take to mean “truth is a property of propositions”, is a half-truth. There is a very important way in which propositions are the most common locus of truth—for us, since we are essentially discursive creatures or creatures of λόγος. But this is not the most primordial sense of truth—discursive truth is itself always grounded in a deeper openness of reality to comprehension that makes discursive truth possible. To put it very simply: we could not grasp or express discursive, propositional truths of the form “S is P” if S and P and their relation where not already given to us in such a way that we could grasp them in their belonging-together and thus come to know them precisely in this belonging together.
So even where Caveman gets close to saying something true, that “truth is a property of propositions,” he’s right only with a series of necessary qualifications.
5. The world can cause us to hold certain beliefs. However, neither the world nor some notion of unchanging Forms decides which description of the world is true. The world does not speak or provide descriptions. Human beings do.
5. Okay, I have decided that this is not a true description of reality.
See the problem?
The problem is an equivocation on the verb “decide.” In one sense, as creatures capable of knowing or believing, it is up to human beings to ‘decide’ what to believe. On the other hand, the way that reality is is not a matter up to human ‘decision.’ Reality is the way it is, regardless of whether human beings ‘decide’ otherwise. If Caveman seriously disagrees with this, I have a simple challenge for him: I challenge him to ingest a large quantity of cyanide and ‘decide’ that cyanide is non-toxic to human beings. If reality is controlled by human decision, he should not have a problem doing this and not dying. I maintain “Cyanide is a lethal poison to human beings” is a true description of the world. I further maintain than no amount of human “description” can change this fact.
We can do another thought experiment to bring this home: suppose that the earth became unstable for some reason and was soon to explode, much like Superman’s home planet Krypton. Suppose also that (for some odd reason) Caveman was the one who was tasked to find a solution to the imminent explosion of the earth. His solution is “Because the world does not decide what is or is not true, it is not true that ‘the earth is going to explode’. Nor can anything in the world ‘decide’ whether the earth does explode. These things—’facts’ or ‘truths’ or ‘knowledge’—are all contingent on human description. So all we need to do, as human beings, is to describe the earth as ‘not going to explode’ and it will become true that the earth is not going to explode.” Do you think that would work? I think *KABOOM*.
If human ‘decision’ could alter reality by means of ‘description,’ why would we not redescribed reality into some kind of ideal state for human beings? Why do we not live in a perfect world, if it is entirely within our power to create reality as we see fit by description?
Oh, wait, I think I know! It’s because this is bullshit, and we can’t actually change reality by redescrbiing it, isn’t it? Damn. I knew this was too easy.
6. That does not mean that truth, facts and knowledge are subjective. It means that they are a product of shared vocabularies, language games, social practices, in short, forms of life which are again contingent upon and conditioned by historical, social, environmental, and cultural factors and, in the final instance, human evolutionary biology.
6. Time to cut the bullshit. This means that we cannot have knowledge of reality. THAT is what the denial of Platonism MEANS, as I’ve said. “Contingent, historical, circumstantial truth which is produced by a variety of social factors” IS NOT TRUTH.
Caveman is putting forward a theory of reality that serves as a DEFEATER for all theories of reality INCLUDING HIS OWN. If this account is TRUE, then it itself is merely a product of some historically contingent form of life, etc., etc., and “in the final instance” of human evolutionary biology. In other words, he is FIRST a SOCIAL CONSTRUCTIVIST about reality, but SECOND (inconsistently) a BIOLOGICAL REDUCTIONIST.
Neither of these things is coherent, either with the other, or with itself.
Social constructionism fails because it is self-defeating; if true, it is an unwarranted theory, because as a theory (like every theory) it is a mere social construction or convention.
Biological reductionism fails because it is self-defeating; if true, it is an unwarranted theory, because as a theory (like every theory) it is merely the outcome of mindless biological forces.
Each theory provides its own defeater, because it provides a defeater for all theories.
Any theory that provides a defeater for all theories, including itself, can be immediately rejected as unwarranted and wholly irrational.
So, that’s what I’ll do.
In this case, each theory also instantiates a performative contradiction insofar as the one who puts forward the theory intends that it be taken to be a true theory about nature of reality—which means that the proponent of the theory, despite his wishes, is committing himself by the very fact of offering a theory of reality, to the view that REALITY CAN BE KNOWN, or in a word, to PLATONISM.
Nietzsche understood this: TRUTH stands or falls with PLATONISM. That is why he said things like this
What we can see from this is that Caveman is one of those sad specimens of the 20th and 21st centuries, a feeble Nietzschean. He thinks he is a late-Wittgensteinian, but of course he isn’t consistent in any way, nor is there anything Wittgenstein discovered that Nietzsche was not aware of.
Caveman’s problem is not (yet) the wild incoherence of Nietzsche or the late Wittgenstein. Caveman’s problem is that he sees, dimly, that his shallow Nietzscheanism cum Wittgensteinianism requires him to reject Platonism—but his isn’t actually prepared to DO THAT, since that entails giving up the idea of TRUTH once and for all.
This is sane, to an extent, insofar as the rejection of TRUTH and REALITY is tantamount to embracing the irrational void of pure nihilism—but the inconsistent attempt to embrace the nihilistic void is, if anything, worse. It merely makes one a failure on all sides, a half-and-half, a lukewarm neither-this-nor-that, a rebel when convenient, but utterly conventional when that is convenient. “Hypocrite” would be another word.
But here’s the deal Caveman: YOU DON’T GET TO RENOUNCE PLATONISM AND KEEP IT TOO.
It’s one or the other: BEING or NOTHINGNESS; PLATONISM or NIHILISM.
And lest I be accused of putting to much weight on Nietzsche’s assessment of meaning of Plato (although Nietzsche, as his arch-enemy, understood Plato better than almost any other thinker), let us add some additional testimony:
7. We communicate successfully every day, and we use knowledge successfully every day, because we share imagined (and conditioned) realities and social practices on many levels.
7. What’s amusing is that Caveman thinks our success in knowing and communicating shows that we can “do without” Platonism.
Actually, what it shows is that Platonism is true; that is, we can know things and communicate them.
At bottom, Platonism is the theory of theories, the theory we can know things. No anti-Platonism can be coherent, since it has to assert we cannot know anything to be true, and so, by its own (anti-) theory, it cannot know what it asserts as true to be true. Caveman is merely another in a long line of people trying to escape truth by asserting the “truth” that “there is no truth” or to escape knowledge by claiming to know that “nothing can be known.” Caveman fails, and all such attempts will always fail, forever and necessarily.
8. Truth, knowledge and facts can always be redescribed by changing the language game, by changing the habits of speaking, by scientific research coming up with better theories, better descriptions that pragmatically explain better, work better according to what we want to achieve.
8. This is simply the thesis of the sophists, that because we speak about reality, we can change reality by changing the way we speak. See above for why that doesn’t work.
Caveman thinks he is being bold and new. But there is nothing new here. It is the same old sophistry that philosophy, in the person of Socrates, rose up to destroy.
Platonism is the view that, not man, but reality and truth are the measure of all things. The fact than it is man who does the measuring does not change the fact that what man measures is not man’s creation, nor is it under man’s arbitrary control.
This is of course how SCIENCE operates. Human beings gain what technological power and mastery over nature they have, only insofar as they submit to the objectivity of reality. Here is Bacon, one of the founders of empirical scientific method making this point:
The postmodern rebellion against reality is, to paraphrase Sartre, a useless passion.
9. Plato’s hypothesis of truth, knowledge and facts as unchanging essences (or “The thing in itself”, in Kant’s description) — only every seen as poorly reflected images on a cave wall — is entirely optional.
9. Platonism is “optional” only so long as you are willing to regard reality, truth, and knowledge as “optional.” And it is far from clear that that is even a coherent thing to do.
Caveman keeps making assertions which have the appearance of being meant as possibly true assertions—but since he assures us repeatedly that “truth” is a kind of social fiction (or perhaps biological fiction; see Nietzsche’s remark above)—this is in vain, a useless passion.
It is not clear that it is in any way meaningful to say that everything is a fiction, an illusion, a falsehood, etc., since these very concepts of “fiction,” “illusion,” “falsehood” seem to by parasitic on the idea of truth.
And the idea of truth is ultimately the same as the truth of ideas, that is, of an intelligible reality which shows itself to the human mind in such a way that it can be known.
Caveman has failed in his attempt to persuade me to reject truth in favor of fiction, to reject philosophy in favor of sophistry.
I remain, as always, a friend of truth, a seeker of truth and a friend of wisdom.
Which is to say, a philosopher.
Which is to say, a Platonist.
