Humans have all sorts of goals, from virtue, to beauty to truth, to happiness and pleasure. How we prioritize these goals can have a huge impact not only on how we act but also on how we think.
Say you prioritize your own happiness over truth for instance, then you will be more inclined to believe in fantastical things simply on account of their hoped-for reward. On the other hand, if you prioritize truth over your own happiness, you will certainly want to dismiss any hope as vain when it is fantastical.
I don't wish to imply that realism and happiness are mutually exclusive, but as this is a theme that has come up in numerous conversations recently, I am curious to see how my friends and followers tend to answer the question. Please don't hesitate to comment with your reasoning.
