If, on the other hand, the student had first noticed the Line of Head, he would have been able to tell the subject that the promise of success was not backed up by the intelligence or the mentality.
As regards the future being foreshadowed, it has been demonstrated that the brain is always growing, changing, increasing, or diminishing.

These changes commence years before the effect is shown by the thoughts or actions of the individual.

A boy ten years old may at that point commence a development which will not be felt until he is thirty, and then it may change his whole life and career.

As this development commences at ten, even at that age it has affected certain nerves, and they in their turn have already affected the Line of Head--a full twenty years before the point of change or action has been reached.

It therefore follows that the future may be seen and told by a careful examination of the hand which, as Aristotle has said, is the "organ of all organs, the active agent of the passive powers of the entire system." THE LINE OF HEAD AND ITS VARIATIONS The Line of Head (page 11), or indication of the Mentality of the subject, must in all cases be considered as the most important line on the hand.
