When a man asks himself what is meant by action he proves that he isn't a man of action. Action is a lack of balance. In order to act you must be somewhat insane. A reasonably sensible man is satisfied with thinking.
There are few things more dreadful than dealing with a man who knows he is going under, in his own eyes, and in the eyes of others. Nothing can help that man. What is left of that man flees from what is left of human attention.
