An article from salon.com on Monday reminds us that philosophy matters, or (as I discussed a bit here) really trying to live the courage of your convictions, to live a life dictated by your philosophy rather than just going on with the crowd or what comes naturally, will more often than not make you a crank and/or asshat instead of a super-enlightened, saintly being.
Why? Because even if you're smart, you're probably not THAT smart; a little humility about your own capacity to reason is called for, as is a little charity towards those thoughtful people among those whose views you are so violently objecting to.
(And yes, I do mean to include that crank Kierkegaard in my criticism here, not just Any Rand fans as discussed in the article. Hegel was not so bad as K. thought, and all those happily married people were not just a bunch of sheep.)
