One thing is clear already: there is a direct, inverse correlation between how much actual knowledge and education in philosophy a commentator has, and how dismissive or derisive the are of it.
The people who have made the most egregiously ignorant statements in opposition, have had the least actual training in it.
It is very much like studying History (my area of primary education), in that when all you get is a cartoonish general taste of it, and then you are tested by a teacher, it’s common to develop a child-like resentment of it, and think it is useless make-work.
It is only after you have a fairly thorough understanding of it, that you can start to recognize that it is directly affecting every aspect of your life all the time, and that when you DO understand it, you come to be much more in control of your end of things.
I have no doubt, that the naysayers here wont even begin to change their opinion, no matter how correct and detailed the rest of us are, because it is one of those many subject areas of human life, that you flat out CAN’T comprehend, unless you get enough of the “pieces of the puzzle” to be able to begin to see how everything else fits together.
I understand. Because I have been through having to deal with subjects that I also thought were total crap, and that I derided in exactly the same ways ("no one asked me how to take a square root before I could get a job delivering appliances!" or "I've never had to diagram a sentence even ONCE since leaving high school!") . But I have also eventually learned much more about the subjects, especially including HOW THEY MATTER to everything else, and have been much better off because of it.
One of my favorite posts in this thread so far, is the person who patiently pointed out to the person who claimed not to have a personal philosophy, that actually he very much DID have such. It is the essence of real Philosophy, to declare that you have none.
And to take that point the next step, it is in part by STUDYING philosophy as a subject, that you can DISCOVER what your own philosophy actually is, what parts of other peoples’ philosophies (AKA belief systems) you have accidentally grafter crudely into your approach to life, so that you can finally take full control and responsibility for all of your life.
One big application: our elections. Those who have both a thorough grounding in History, and in Philosophy as disciplines, were easily able to see through the manipulations, the lies, and especially the counter-lies that our gaggle of politicians succeeded in foisting on the country.
