> I never feel like I know anything with 100% certainty. Every piece of knowledge I have is more like a probability in my mind. This should be the default mindset of every thoughtful person! We are all imperfect. Our vision, hearing, reasoning and perception are all imperfect. Eyewitnesses to a crime routinely describe completely different suspects/activities, despite being completely earnest in their accounts. I believe it it absolutely crucial to maintain a certain level of doubt about everything, at all times, based on the fact that we are imperfect beings that have imperfect knowledge and imperfect reasoning skills. I further believe that the humility that this constant awareness brings is useful and necessary. Beware people who are absolutely certain about things.
