There is a pretty innocent reason for why those passages look meaningless– they're all jargon filled when you don't know what the jargon means you will likely fail to understand what the passages mean. A paper on quantum chromodynamics is going to look meaningless to someone who doesn't know what quarks, quanta, flavor symmetry, gluons, hadrons, chirality etc. refer to. Similarly, I assume most people here have no idea what Plotinus means by "Being", "Essence", "Intellectual-Principle", "form" etc. I've done course work on Neo-Platonism and I don't remember what all of that was about. The same goes for the other passages.

Now Plotinus is particular might still be meaningless since some of that jargon is actually meant to refer to real things that he thinks exist. And insofar as he is referring to non-existentials whether or not the passage is meaningful depends on your philosophy of language (it is either false, meaningless or non-propositional).

Occasionally you find an analytically trained philosopher working on continental subject matter and they tend to assure me that the jargon and unconventional usage actually DO mean things. What does happen, I think, is that the jargon and unconventional language gets abused by stupid people who don't really understand the original philosopher but try to use their language. Since the language is so hard to parse in the first place it ends up being pretty easy for a charlatan to survive. Particularly if the charlatan isn't actually working in a philosophy department where there are people to challenge her.

In that vein, I don't think "bad continental philosophy" consists in Foucault and leading figures like him but many of their insipid followers on the continent and off who were never trained to express themselves clearly and logically.

This is why all philosophers should be trained in the analytical tradition, even if they want to work in other areas.

No, the passages given in the article have much deeper problems than just the jargon. The jargon only serves to defend these texts from criticism; because they're difficult to understand, anyone who says that these passages are wrong or mere gibberish can be accused of not understanding them. This defense works even if the critic understands the text perfectly.

Uh, maybe. I'm willing to hear arguments to that effect. But you didn't give one.

I think Plotinus is definitely wrong, I don't know enough about Hegel to form an opinion, and I disagree with what I know of Foucault. But that doesn't make what they wrote meaningless.

Arguments to what effect? Are you objecting to my claim that "you don't understand" is used inappropriately to defend bad philosophy, to the claim that jargon makes it easier to do so, or to my claim that the passages have deeper problems?

Comment author: Jack 18 May 2009 03:17:50AM *  5 points [-]

Sorry, I should be specific. I don't think the passages, or the writing of these philosophers and the well-know continental philosophers, generally, are gibberish. I think the reason people think they are gibberish is because of the jargon. I would like to see an argument for why I should consider them gibberish for reasons other than jargon I don't understand.

And since I hold that the jargon is meaningful, I don't think that the jargon "only" serves to defend the texts from criticism (did you really mean "only")? I also, deny that a critic who understands the text perfectly would argue that the text is meaningless– but that issue will be addressed by the argument I ask for above.

(Note: Of course there are deeper problems to these passages. But those problems don't have anything to do with the syntactic rules for sentence formation or semantic rules for word usage. In other words, the problem isn't that their gibberish.)

I define "gibberish" to mean "difficult to understand and entirely or almost entirely false or meaningless". Since you have said you think Plotinus and Foucault are wrong, and I think we can agree that they're at least somewhat obfuscated, then we must have different definitions. What's yours?

Comment author: Jack 18 May 2009 04:50:02AM 4 points [-]

I define gibberish as "difficult to understand and entirely or almost entirely meaningless". I think Plotinus and Foucault are "difficult to understand and entirely or almost entirely false". A statement is meaningless if it either fails to follow rules of syntax, i.e. "Running the the snacks on quickly!" or semantics, i.e. "Green ideas sleep furiously."

The distinction is actually pretty important. If you know something is meaningless then you can move on, but you can't decide something is false without first considering the argument, obfuscated or not.

There is some middle ground when it comes to arguments about things that don't exist. The trinity argument (and probably Plotinus) appeals to something that doesn't exist and so it says things that would be meaningful if the holy trinity was real but can't really be evaluated since there is no such thing. Obviously there is no reason for you to care much about this argument. But I don't think Hegel, Foucault or Heidegger and the other usual suspects are talking about things that don't exist.

Syntax does rules necessarily broken imply meaninglessness not.

Comment author: Jack 19 May 2009 01:24:29AM 2 points [-]

Semantic rules aren't holding knives to the throat of meaning either.

So yeah, it is more complicated than what I said before because our brain is pretty good at fixing broken sentences with context. Rules for context and pragmatics should also be included in requirements of meaningfulness. My bad for missing that.

The word "exist" confuses you. Does three exist? Maybe yes, maybe no; what real-world consequences would arise from three existing or not? If a tree falls in the forest, etc.

Humanity to date knows two families of statements that appear to possess truth values independent of the listener's psychology:

1) Experimental results, objectively verifiable by repeating the experiment.

2) Axiom-based mathematics, objectively verifiable e.g. by proof checking software.

Of course people can make personally or culturally meaningful statements that don't fall into type 1 or 2. Just don't delude yourself about their universal applicability or call them "science".

Comment author: Jack 18 May 2009 04:24:51PM *  5 points [-]

First, the word exist does not confuse me anymore than it confuses anyone else. If you think it does you should say why, since it wasn't explained in the previous post. The ontological status of numbers is a classic and ongoing philosophical dispute, whether there are real-world consequences to the question, I don' t know but even if there aren't it does not follow that the question has no truth value.

Experimental results don't verify anything, they either falsify or fail to falsify huge sets of different scientific propositions. When an experimental test of a hypothesis comes up false one can dismiss the hypothesis or one can dismiss any number of auxiliary assumptions that you had when you made your hypothesis. It is the job of scientists to find the best interpretation of experimental results according to criteria such as parsimony, consistency, usefulness, etc. But scientific theories are better understood as best working interpretations not objectively verified truths that exist independent of human interpretation. Metaphysics uses the exact same criteria to try and figure out the best interpretations with regard to other issues for which experiments are sometimes relevant but often not.

Also, axiom-based math can't really be addressed by proof checking software since you can't program proof-checking software before discovering some axiom based mathematics. Plus it isn't like we started believing math was true 60 years ago. We figured it out because our vulnerable, biased, human brains happen to have considerable abilities for ascertaining the truth.

Anyway, we also know things based on non-experimental observation and data gathering. This includes non-scientific things like whether or not there is a car on the street as well as the less experimental sciences like, astronomy, linguistics and economics. Knowledge in linguistics and economics is certainly somewhat more precarious than in physics since in the former fields it is by turns often impossible or unethical to run experiments. But that doesn't mean the insights in these fields aren't useful. I have no problem calling them sciences.

Of course there are the other so-called analytic truths- the whole set of possible tautologies one can make with natural language and entailment relations between categories. Altogether, I think there are quite a few more statements that possess truth values than just experimental science and axiomatic mathematics and they all involve human interpretation.

This isn't a reason to be frustrated, it just means we don't get to take an aerial picture of the terrain in making our map, we've got to figure it out by making best guesses according to limited information.

Finally, so what if some philosophy is simply personally and culturally meaningful statements? That isn't a reason to reject them as bad thinking.

You might have missed my emphasis on well-transferable truth value. Even if the "ontological status of numbers" question has a well-defined truth value to you, or non-experimental economics, or linguistics... how do you transfer the answer between individuals? I've indicated two methods of independent verification that correspond to science and math; is there a third one? Persuasive-sounding literature doesn't cut it, because it can be used for religion just as well. About your final question, what makes philosophy distinct from literature?

So you maintain that anything which follows a few syntactic and semantic laws cannot be gibberish? I disagree; text can have meaning and still be gibberish. Consider a sequence of words drawn uniformly at random from a dictionary, then slotted into a repeating template like (noun) (verb) (article) (adjective) (noun). The template ensures that no rules of syntax are violated. A few constraints on the vocabulary can ensure there are no egregious violations of semantic rules, like green ideas and furious sleeping. Restrict the vocabulary to a few hundred concrete words and you can even ensure that every sentence makes a testable prediction. But it's definitely gibberish.

Comment author: Jack 18 May 2009 04:56:52PM 2 points [-]

Well there are a lot of semantic rules and plenty that we've haven't formalized. So I'm not convinced anyone now alive could write such a program. But I'm not a programmer so maybe someone has proved me wrong. However,iIf they were successful I don't think I would consider the result gibberish- especially if each sentence made a testable prediction. In this case wouldn't some of the predictions be true? If so then it is clear that your definition is not broad enough.

Thats troubling since I had already concluded your definition was too broad because it seemed to include important but complex and falsified scientific claims,
