When I graduated college as a philosophy major, I left with an uneasy feeling. Craving utility and connection with my childhood interests I took up software development.

I'm glad to finally see an explanation for the letdown I experienced as an enthusiastic but inexperienced scholar. I remember when I asked my first philosophy professor, someone I had struggled with intellectually (and physically during a dinner party) for a recommendation letter to leave philosophy and study law, and his reply that I had "not spent enough time with the classics" for him to feel confident that I was a real enough philosopher.

I am glad now to state that I am not, and that like many my response to its flaws was to turn to other pursuits.

Paul, what do you think of Modern Art, especially painting? It seems to me the very same arguments you made about philosophy hold there. People try to look impressive by doing something opaque and incomprehensible and calling it art. If you don't "get it" that is used as even further evidence as to their genius. It seems to me the same situation you talk about, when there is a market for people producing and consuming such things.

I would love to know your take on the subject.

No, modern science was invented by ibn al-Haytham a thousand years ago. (Spellings vary, but include "Alhazen" and "Alhacen".) He is generally credited with inventing modern optics (along with various geometric results), but the method he invented to give a firm foundation to his investigations into optics was what, today, we call science. Bacon studied him.

In addition to Sokal's hack on "Social Text", I believe that Rob Pike did a test in which random texts produced by running a Markov chain over Derrida were found to be indistinguishable by informed readers from actual Derrida. (I'm probably misremembering at least some details of the actual incident but the gist is, I'm pretty sure, true.)

I've done a bit of research -- the Pike incident involved Baudrillard, not Derrida.

Pike's comment at the beginning of the Markovified text is brilliant:

> For those unfamiliar with M. Baudrillard's work, the thesis of the essay is, in a nutshell, that reality is indistinguishable from good simulation.

1. Seems to me Paul partly rediscovered Buddhism: great Buddhist philosophers of the Great Middle Way school use philosophy to demonstrate philosophy does not work. There is a great analysis of it:

(This is where the Great Middle Way comes from: the middle way between existence and non-existence. We can prove Berkeley wrong just by kicking stone: it would be wrong to assert that that the phenomena don't exist in the casual, everyday sense. However, they don't exist in that sense that if we look deep into it the entity we casually define as a "stone" does not actually have a true and lasting essence, or identity.)

2. However, I believe philosophy, even though usually it is a bluff, is a necessary evil. How can we talk about politics without philosophy? How can one have any political opinion without at least having some ideas of what "good", esp. "a good life" is? (OK you can be an anarcho-capitalist without it but otherwise basically both Liberalism and Conservativism requires some definition of "good".)

I take your point and suggest you go back and explain 'the Greek miracle' as everything after Pythagoras is a distortion.

There is no science before Thales, 600BC. There is general agreement that Thales is first to deduce certainties, implicitly building on inductions. So, the key to explaining the Greek miracle is an inspection of what we know about Thales. Pythagoras reversed Thales in that he took the integration of induction and deduction and when applied to numbers reified them making them subjective. The history of mathematics argued over the source of a numbers certainty (cardinality) for 2350 years which mostly consisted of arguments to explain the relation between god and cardinality. God is a bogus concept, it has no existential content. Kant refusing to accept the obvious devloped an argument that took the god/cardinal problem and made it impossible to integrate them in the hope of saving the god part from reasoned inspection. From Kant developes a new aecular, subjective view of cardinality. Excepting Ayn Rand, no one has ever gone back to Pythagoras to correct his mystic error.

My position is large in that it questions Pythagoras and so, everything that follows him. All phillosophy today is still Pythagorean in that it implies agreement with his subjective stance. The Greek miracle is in fact the discovery of objectivity (reasoned argument) based on the integration of ordinal and cardinal numbers, or concretes and abstractions, which is the same thing. Pythagoras confused numbers which are abstractions with their concrete instances. This has the effect of reversing the Thalean integration and re-establishes the mind/body dichotomy as the norm, making objectivity impossible.

Consider any "vocalizable concept" X. There are 4 directions you can move from X.

"Meta" - you can ask the set of questions "what can we say about claims about X?"

"Anti-meta" - you can ask the questions "what can X say about other things?" (make X a meta-concept of some other concept)

"General" - you can ask the question "do there exist generalizations of X?" (commonly known as abstraction, although the term is ambiguous - generalization is more precise)

"Specific" - you can ask the question "do there exist instances of X?"

Answering questions in these 4 directions gives you information about what you really want to know - what is X? What is "true" of X?

Philosophy is exploration and characterization of this "idea space." Nothing more. Nothing less. Very useful, if people would only do it once in a while.

---

Quick example:

"What is free-will?" = X

Meta:

Does free-will correspond to a thing? What classes of things is it in? What are our intuitions? What can we meaningfully say about free-will?

Anti-meta:

Suppose we define free-will well. What concepts does it enable? Are those concepts meaningful?

General:

Are there generalizations of free-will? How about just plain old "will"? What can we say about "will"? How about "freedom?" What's that?

Specific:

Are there any hard-and fast examples of free will? Are there any "thought-experiments" we can perform to try to shake out our intuitions? For instance, if everything were systematic/deterministic, what would this imply?

---

My claim is that this method is useful for getting terms to be well-defined in the way that PG requires of math. You just keep doing this sort of analysis over and over until you get down to essential definitions.

Best to start from the bottom, though.

"Of all the useful things we can say, which are the most general?"

As a hill-climbing algorithm, wouldn't this approach tend to result in the local optimum rather than the most general truths?

That is an interesting question. I wonder if there is even a way to know if the space has merely local maximums.
