But one thing must be remembered, that man shows the lines engraved upon his mind in his form, expression, in his movements, words, in his imagination and action, and it is possible to detect a man from his word before his action, or from his movement before his action, or from his expression before his words, or from his form before even he had time to imagine. Therefore the knowledge of this can save a great deal of trouble in life, if man only knows beforehand how to act with different people.
