Philosophy is basically logic. What you do is start with a premise or two and try to create a logically valid argument based on them. In essence, it's story telling.
Would that that were true. However logic as used by philosophers is not a rigorous process of inference.
Well, this could come down to us failing to agree on what is meant by logic, rigour and philosophy.

That's because when people have tried; Russell's logical atomism, Tractatus era Wittgenstein, the Vienna Circle spring to mind, what they are eventually compelled to concede is that pure logic simply cannot be rigorously applied to any language in which there is no consensus on the definition of concepts such as logic, rigour and philosophy.

No, but anyone who has ambitions of being taken seriously as a philosopher needs to be handy with them.
A_Seagull wrote: ↑Thu Jan 25, 2018 12:13 amIf this were not so then one might have to conclude that a peanut butter sandwich was better than perfection.
Well, as I said, you could pick your premises to validly conclude that.
A_Seagull wrote: ↑Thu Jan 25, 2018 12:13 amAnd yet many would-be philosophers believe in the sanctity of logic as though it is a God-given certainty.
And when they pull their finger out and actually study philosophy, they discover this is not true.
A_Seagull wrote: ↑Thu Jan 25, 2018 12:13 amHence the assertion that philosophy has similarities to religion.
I'm sure you could construct an argument that reaches that conclusion, but I don't think the initial premise is sound; it certainly isn't exhaustive. One difference is that religions generally have a catch all to cover anything that we cannot currently explain; some version of 'god works in mysterious ways'. There are some interpretations of quantum mechanics which make essentially the same claim, some physicists think Bell's theorem proves it. It's also the basic premise underpinning some versions of chaos theory.

Well yes; there are plenty of people who confuse a valid conclusion with a sound one.
A_Seagull wrote: ↑Thu Jan 25, 2018 12:13 amAnd people write these opinions as those they were unique truths, and so they end up writing BS.
Happens in science too. Phrenology. Eugenics. Loop quantum gravity, string theory, modified Newtonian mechanics or all the above. There is a lot more mathematics than applies to any existing physical system.

Empiricism.
A_Seagull wrote: ↑Thu Jan 25, 2018 12:13 amHume's fork is the only suggested process, but it is ignored by most philosophers. But if it were not ignored 95% of philosophical writing would be 'cast into the flames'.
Well, Hume's fork is just pointing out that there is rationalism and empiricism. Which any philosopher worthy of the name already knows.
