Your assumptions are your windows on the world. Scrub them off every once in a while, or the light won't come in.
You feel humiliated, my young man, because thinking you understood so much so well, you suddenly find that many very apparent things were unknown to you. Thinking you were one of the Lords of the Galaxy; you suddenly find that you stand near to destruction. Naturally, you will resent the ivory tower in which you lived; the seclusion in which you were educated; the theories on which you were reared.
