Wisdom

"'...You have a strange way about you, Dr. Grumman. You ever spend any time among the witches?'
'Yes,' said Grumman. 'And among academicians, and among spirits. I found folly everywhere, but there were some grains of wisdom in every stream of it. No doubt there was much more wisdom that I failed to recognize. Life is hard, Mr. Scoresby, but we cling to it all the same.'"
