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.

Life is short for those who are truly able to understand that one day the entire world will come to a complete end. Not everyone is capable of that. Not everyone has the ability to comprehend what going away for all eternity really implies. There are too many distractions, hour by hour, minute by minute, to hinder such an understanding.

A lot of people experience the world with the same incredulity as when a magician pulls a rabbit out of a hat.…We know that the world is not all sleight of hand and deception because we are in it, we are part of it. Actually we are the white rabbit being pulled out of the hat. The only difference beween us and the white rabbit is that the rabbit does not realize it is taking part in a magic trick.
