Your Epistemological Oyster

If one cannot sufficiently justify a belief that they hold, then it is merely an opinion devoid of knowledge, regardless of that proposition's actual truth value. Since the truth of an opinion is always contingent on unpredictable conditions and is thus subject to error, we ought to never assert them as fact, lest we foolishly rely on something inherently unreliable. There is nothing more pitiful than a bullshit artist who can't smell the stink of their own artwork. People do this all the time. Rattle off other people's ideas as if they were their own, without actually fact checking them in depth as to whether they're ultimately true or trivial. Silence is definitely superior to a baseless opinion. Controlling your tongue can prove to be even more difficult than moderating the appetite. We ought to be mindful of this. Ignorance is only bliss up until the point where you realise your folly, then it quickly goes nightmare mode like a manic depressive on the tail end of a methamphetamine binge. Consistency is key here, but if we are to be consistent, then we must start with first principles. A little Cartesian scepticism goes a long way. Question everything, even your own existence. Question it hard enough, and eventually you arrive at a matter of undeniable certainty. I am. I exist. Being is what I am. Because if I'm not, then whom or what is questioning? From here on out, the cosmos is your epistemological oyster.
