"Elsie Lincoln Benedict is known nationally, having conducted lecture courses in many of the large Eastern cities. Her work is based upon the practical methods of modern science as worked out in the world's leading laboratories where exhaustive tests are applied to determine individual types, talents, vocational bents and possibilities."--San Francisco Bulletin, January 25, 1919.
Constant repetition of the same kinds of thoughts or emotions finally makes permanent changes in that part of the body which is physiologically related to these mental processes.
The Evolution of the Jaw
¶ The jaw is a good illustration of this alliance between the mind and the body. Its muscles and bones are so closely allied to the pugnacity instinct center in the brain that the slightest thought of combat causes the jaw muscles to stiffen. Let the thought of any actual physical encounter go through your mind and your jaw bone will automatically move upward and outward.
After a lifetime of combat, whether by fists or words, the jaw sets permanently a little more upward and outward--a little more like that of the bulldog. It keeps to this combative mold, "because," says Mother Nature, the great efficiency expert, "if you are going to call on me constantly to stiffen that jaw I'll fix it so it will stay that way and save myself the trouble."
The author makes the claim that a cerebral type must have a large head/brain and a disproportionately small, frail body. This physical structure is said to be the cause of the behaviors peculiar to the type. Yet all of the behaviors are exact peculiarities of myself and I do not fit the physical description of the type! I have a small head on a small frame. So how is that possible? The logic of this book fails. It falls into superficial generalities which fail the test of reality. If I happened to have a big head on a small body I would probably think this book was great and so very accurate, but fortunately I have a smaller head and can as a consequence comprehend that this book makes false claims.
It has contradictions. First they say not to jump to conclusions, then they say that these different types of people will always be this way with no variation.
This book is awash with stereotypes and veiled as being scientific. Supposedly you can analyze people by their body types. All fat people are jolly. Most Jews are fat. Most millionaires are fat. Fat people are the first to line up when restaurants open. I had to stop reading this one, it made me so mad.
