Let me ask you something else: If someone who "applies logic and reason to how we should live our lives or structure our societies" can't avoid philosophy "whether he likes it or not", then why start a thread "why is philosophy important" ? Isn't it like asking "why is thinking important" ?
If people ridiculed thinking then yes.
And those competing notions are competing philosophies ? You said before that Lenin's philosophy was clearly wrong.
No I didn't. I said "The philosophies of Lenin have been so far found to be failures." First let me state that I misspoke. I meant the philosophies of Marx and Engels and not Lenin. I apologize for any confusion. FWIW, I think Marx, Engels
and Lenin had some very important things to say and contribute to politics and economic theory. I hope that they are never taught as simply something that failed. That would be a huge mistake in my mind.
Was there any way to prove that logically at the time ? Because if there was, what was the need for philosophy ? We could have just used logic and reason to prove him wrong.
? "Prove him wrong"? How would one "prove him wrong"? I don't understand. What do you mean by "prove him wrong"? FWIW, Lenin never had the opportunity to institute his doctrines. After his death Stalin was successful in his power struggle with Trotsky whose views were closer to that of Lenin. I don't think one can honestly say that Lenin or even Marxist philsophy was proven wrong. I stand by original statement with the change from Lenin to Marx and Engels.
Don't get me wrong. I'm not pro-communist at all. I just don't see such philosophies as "wrong" and I see little to be gained by such rhetoric. I would think such a label would be propaganda and not the result of rigorous philosophical analysis and would have no place in political and economic philosophy.
So "rigorous skepticism" = "philosophy" ? Is that what you're saying ?
No, I'm saying rigorous logic is a part of philosophy.
I never said that philosophy is antithetical to reason, logic and well thought-out plans. You seem to call philosophy the "rational thinking about something great". I'm not going to discuss the definition again, but let me present once more a hypothetical situation: Say I'm someone who hasn't studied or read any philosophy, but I have a degree in economics and history and am also a "rigorous skeptic". How exactly will my lack of philosophical education affect my political or social thinking ?
A philosophical education could give you far more tools for the job and reduce your learning curve should you decide to involve yourself with politics.
A person doesn't need a degree in business to open a business. It can help though. Often times a person will learn by the seat of their pants what is taught in school. A formal education can assist a person and help that person avoid pitfalls.
When I sold my house I made a lot of dumb mistakes that cost me a lot of money. I wish I would have used a Realtor and benefited by their knowledge. It certainly wasn't necessary though.
