You can never know if a person forgives you when you wrong them. Therefore it is existentially important to you. It is a question you are intensely concerned with. Neither can you know whether a person loves you. It’s something you just have to believe or hope. But these things are more important to you than the fact that the sum of the angles in a triangle is 180 degrees. You don't think about the law of cause and effect or about modes of perception when you are in the middle of your first kiss.
Jostein GaarderWhen you realize there is something you don't understand, then you're generally on the right path to understanding all kinds of things.

Jostein GaarderSocrates himself said, 'One thing only I know, and this is that I know nothing.' Remember this statement, because it is an admission that is rare, even among philosophers. Moreover, it can be so dangerous to say in public that it can cost you your life. The most subversive people are those who ask questions. Giving answers is not nearly as threatening. Any one question can be more explosive than a thousand answers.
