One of the hardest things about being a human is there's no way to know if a doubt is worth considering. So we all just flounder around with whatever answers we can come up with, or we live our lives dominated by anxiety. Or i guess we find a way to be comfortable with uncertainty. But inevitably, everyone has a moment in their life where they can't feel comfortable with uncertainty about something, and so their mind breaks, and they either succumb to the desire to allow knowledge to slip through their grasp completely, or they give in to their doubt. The ones that give in to their doubt find there is no certainty to be found there either. The socratic method always leads to more uncertainty if taken to its logical extreme. So they realize that sometimes in life, knowledge is not possible, but they must nevertheless make important decisions without it. We all come to a time when a life altering decision must be made when there is no rational way to make it. 

In these moments we can choose who we are. More so than in any other moments. That is what makes the human experience tragically beautiful. Moments where the only meaning is what we create. Where we come to a crossroads of nihilism and existentialism.
