This is the perpetual and pitiful tragedy of the practical man in practical affairs. He always begins with a flourish of contempt for what he calls theorizing and what people who can do it call thinking. He will not wait for logic-that is, in the most exact sense, he will not listen to reason. It will therefore appear to him an idle and ineffectual proceeding to say that there is a reason for his present failure. Nevertheless, it may be well to say it, and to try and make it clear even to him.
