26 THE GLANDS REGULATING PERSONALITY 



the secrets of our inmost being. They are the well springs of life, 

 the dynamos of the organism. In trailing their scent we appear 

 to be upon the track not only of the chemistry of our bodies, but 

 of the chemistry of our very souls. An increasing host of facts 

 and studies marshal themselves solidly for that declaration. 

 Endeavor to conceive the consequences and possibilities for the 

 future. A synthesis of the known in the field provides even now 

 means of understanding and control of the perplexities of human 

 nature and life that are like a vista seen from a mountain top 

 after the lifting of a fog. 



The most precious bit of knowledge we possess today about 

 Man is that he is the creature of his glands of internal secretion. 

 That is, Man as a distinctive organism is the product, the by- 

 product, of a number of cell factories which control the parts 

 of his make-up. Much as the different divisions of an automobile 

 concern produce the different parts of a car. These chemical 

 factories consist of cells, manufacture special substances, which 

 act upon the other cells of the body and so start and determine 

 the countless processes we call Life. Life, body and soul emerge 

 from the activities of the magic ooze of their silent chemistry 

 precisely as a tree of tin crystals arises from the chemical reac- 

 tions started in a solution of tin salts by an electric current. 



Man is regulated by his Glands of Internal Secretion. At the 

 beginning of the third decade of the twentieth century, after he 

 had struggled, for we know at least fifty thousand years, to 

 define and know himself, that summary may be accepted as the 

 truth about himself. It is a far-reaching induction, but a valid 

 induction, supported by a multitude of detailed facts. 



Amazingly enough, the incontestable evidence, that first 

 pointed to, and then proved up to the hilt, this answer to the 

 question: What is Man? has been gathered in less than the last 

 fifty years. Darwin and Huxley, and Spencer, who first opened 

 men's eyes to their origins, were ignorant of the very existence 

 of some of them, and had not the faintest notion or suspicion of 

 the real importance or function of any of them. 



The Prejudices of Philosophers 



Now, there are certain prejudices and problems which appear 



rudely brushed away by the dogmatic arrogance of the 



principle lUted What, you say, is Man but an affair of his 



peculiar gland chemistry? But what of mind, soul, conscious-
