Mark Twain cannot be defined.

I read from Mark Twain's lips one or two of his good stories. He has his own way of thinking, saying and doing everything. I feel the twinkle of his eye in his handshake. Even while he utters his cynical wisdom in an indescribably droll voice, he makes you feel that his heart is a tender Iliad of human sympathy.
