Although the art of healing is as old as recorded history, the science of medicine has developed recently.
Medical schools emphasize scientific diagnosis and treatment and understanding of research.
The success of the healer depends also upon a warmth and flexibility of personality, largely matters of natural endowment and early training. The divisions of a lecture are always right as long as they are necessary to edification, and always wrong when they are thrust upon the atention as divisions only. So-called white dwarf stars are very old stars that have collapsed in upon themselves, thus becoming much smaller than they were at an earlier age while retaining the same mass. As a result of their evolution, they are almost unbelievably dense. From the law that every active force produces more than one change, it is an inevitable corollary that through all time there has been an evergrowing complication of things.
