I have found that all ugly things are made by those who strive to make something beautiful, and that all beautiful things are made by those who strive to make something useful.
To cut out every negative root would simultaneously mean choking off positive elements that might arise from it further up the stem of the plant. We should not feel embarrassed by our difficulties, only by our failure to grow anything beautiful from them.
There are few earthly things more beautiful than a university a place where those who hate ignorance may strive to know, where those who perceive truth may strive to make others see.
