The modern psychologist adopts a system of psycho-analysis in order to investigate the state of mind of his patient, and the barrister in the law court cross-examines in order to investigate the truth of the case. All these methods are more or less useful when they are rightly practiced, but the chief thing for getting to the mind of a person is to see the person, in his form, in his expression, in his movements, in his words, in his imagination and in the way of his action. And the principal thing which helps in seeing the mind of another person is the light of intuition. Nothing else, neither rules nor studies nor standard of understanding can help without the development of intuition.
