How to Do Philosophy

FWIW, PG's thoughts on philosophy are largely confined to "analytic philosophy", which I agree suffers from the problems he talks about. There is a whole other tradition of sorts (sometimes referred to as "continental philosophy"), taking a different path from Kant, including Hegel, Nietzsche, Heidegger, Derrida, Foucault, Badiou, etc. This side of philosophy tends to suffer from being extremely difficult to understand, but yields much genuine insight for those who take the time to study it.

There's also the pragmatic tradition, as DanielBMarkham notes. I'm less familiar with it, but many have seen commonalities between Heidegger and the Pragmatists.

Ayn Rand's writing can be inspirational, but her philosophy was poorly conceived.

"There are things I know I learned from studying philosophy. The most dramatic I learned immediately, in the first semester of freshman year, in a class taught by Sydney Shoemaker. I learned that I don't exist. I am (and you are) a collection of cells that lurches around driven by various forces, and calls itself I. But there's no central, indivisible thing that your identity goes with. You could conceivably lose half your brain and live. Which means your brain could conceivably be split into two halves and each transplanted into different bodies. Imagine waking up after such an operation. You have to imagine being two people."

Whew, I'm glad I just watched Star Trek to learn this, and didn't spend tens of thousands at Harvard. (I'm referring to the numerous times someone was 'duplicated' in a transporter accident)

>I can tell you what an integer is, what a square root is, and what a ratio is, and as a result, I can (by looking it up in a book and typing in the text, heh heh) prove that the square root of 2 can't be expressed as the ratio of two integers.

Not without words you can't.

No, it's for the same reason that intelligent design isn't taught in biology classes, or that the timecube theory isn't taught in physics classes, or that homeopathy isn't taught in med school. Rand's output was pseudophilosophy.

It'd be useful to see some support for your claims about the history of philosophy. Specifically:

1. Aristotle's Metaphysics, and the like, had no effect on its readers. I'd also like a clearer definition of "did something." I.e. does changing the way one thinks about practically theoretical fields "do something?"

2. No one challenged the two until the 1600s. Kant, by himself, isn't a good source since his philosophical agenda was to overthrow the relevance of religion (which was tightly coupled with classical thought). See Allan Bloom's Closing of the American Mind for details.

For my undergrad I studied the classics, and I'd say your generalizations are too general. People, such as Aristophanes, said the same things about Plato in his day that you say in your essay. Yet, generations of great thinkers have chosen Plato over the Cynics and Epicureans, today's relativists and materialists. Your critique of the uselessness of philosophy is more indicative of the fact that many of the humanities in academia today are purposely biased towards relativism or materialism.

While I agree that philosophy should be tested with practice, I don't think practicality should restrict inquiry. Otherwise, we become very short sighted. Math is a great example of this, which you've pointed out in one of your essays.

Finally, you misunderstand Aristotle's support for 'useless' theory. You're confusing 'useless' with 'pointless.' All useful activities are done for a specific goal, they aren't important in themselves. Therefore, the ultimate point of useful activities is by definition 'useless.' Aristotle thinks the final goal we all aim for is happiness, and the highest form of happiness is a kind of knowledge.
