I think it's ironically telling about your opinion on philosophy that your argument is illogical and boils down to:
1. people who aren't philosophers said some bullshit
2. don't you dare point out people who don't do philosophy shouldn't have their ramblings labeled philosophy
Ayn Rand, a 20th century writer without a university education; Paul Graham, a computer scientist; and the Austrian School, an economics movement, are categorically not entities that have produced or ever will produce philosophy.
That's no a No True Scotsman fallacy. It is a strict application of the definition of philosophy, a deep analysis of certain specific topics. Neither Rand nor Graham is educationally equipped to plumb that depth. And, again, the other name you dropped is not even a philosophical school.
> people who aren't philosophers said some bullshit
Wow, I didn't expect to be vindicated quite so definitively when I predicted: "The most likely outcome of that exercise would be for you to invoke the no-true-scotsman fallacy."
> That's no a No True Scotsman fallacy.
It absolutely is:
> the definition of philosophy, a deep analysis of certain specific topics.
I see nothing in that definition about writing in a particular time period or having a university degree, which are the two features you cited that allegedly disqualify Ayn Rand. I also see an awful lot of wiggle-room in the "specific topics" and how one measures whether one's analysis is sufficiently "deep". You exclude economics and computer science from your list of "certain topics" but you don't say what topics are allowed or on what basis this assessment of admissibility is to be made. Your argument is a paragon of muddled thinking, and does more to support my position than refute it.
> Neither Rand nor Graham is educationally equipped to plumb that depth
In his defence, Graham does hold a BA (Philosophy) from Cornell University in 1986.
Is your distaste here due to BA degrees rather than PhDs, a dislike of Cornell, or that Graham didn't chase academic philosophy and join a philosophy department?
