morality is subjective and people don't have free will

[Neo-Scholastic]

That's because you're a nutjob.

On this thread, you've been very disrespectful of me personally and are now resorting to insults.

The part undermines the whole?  That's nonsense.  Does the existence of randomness in quantum mechanics undermine the science.  Does the existence of randomness in the universe "undermine" order?  You're talking poetic rubbish.

If randomness means that anything can happen for no reason at all, then yes, it does undermine scientific inquiry. If on the other hand we are talking about physical operations within certain parameters and the presumption that there is an underlying reason for why particular results manifest, then no.

....questioning an essential and necessary correspondence between reason an intelligible world order raises serious problems with respect to humanities ability to attain knowledge.

Reality is a bitch.  Get over it.

I'll take that as an admission that your view has serious problems.

If you don't stand for something, you cannot stand for anything.

You're talking barely intelligible metaphysical gobbledygook and invoking stupid platitudes?  Get over yourself.  The world is a mixture of the intelligible and unintelligible, and much as you might not like the fact, wishing it away won't make it so.  Our reason and our senses are fallible, and a healthy skepticism is a good thing.

My use of that adage refers to the notion that an existential choice to believe something positive, like the efficacy of reason, is necessary in order to justify subsequent positive beliefs. Your version of skepticism crosses into nihilism. Perhaps the things you consider unintelligible appear that way to you because of your incoherent and self-defeating stance.
