A Note On Self-Deception
There are no guarantees that one won’t deceive oneself about how wise one is. Indeed, the necessarily imperfect relationship between ideas and feelings about what-is-actually-the-case and what is actually-the-case guarantees that everyone (whatever their worldview) will to some degree succumb to that error.
And yet deep inside we know when we are deceiving ourselves. Unless, perhaps, if we are completely crazy. There are no guarantees in life. We just have to do the best we can.
