TEN BIOLOGICAL PRINCIPLES 



THROUGHOUT our studies relating to the force that 

 energizes man and animals and accounts for their intelli- 

 gence, power, and personality, we have found that the rela- 

 tion of the living processes to the genesis of civilized man 

 and his diseases may be expressed by the following ten 

 biological principles: 



1. The pattern of the unicellular organism, with its 

 dominating positive nucleus and negative cytoplasm, is the 

 universal energy formula for animals and man. 



2. In higher animals the positive pole of the bipolar 

 mechanism is generated by the brain; the negative pole is 

 generated by the heart and the red blood cells. Oxidation, 

 as in the carbon lamp, completes the arc. 



3. In both cold-blooded and warm-blooded animals, from 

 the grasshopper to the elephant, with the exception of the 

 higher primates and man, I gram of brain is required to 

 execute 12,115 small calories in 24 hours. 



4. In man, the brain and the thyroid gland rose together, 

 the brain as the universal executive and the thyroid gland 

 as a universal controller of constant adaptive oxidation. 

 The thyroid gland is relatively larger in man than in any 

 other land animal. Both the thyroid gland and the brain 

 exhibit the peak of their dominance in civilized man. 



5. The adrenal glands are larger than the thyroid gland in 

 virtually all the wild land animals, including the ape. In 

 contrast to man the adrenal-gland control is especially 

 marked in the ape. 



6. Intelligence, power, and personality are dependent on 

 the absolute and relative size of the brain, the thyroid 

 gland, the heart and blood volume, the celiac ganglia and 

 plexuses, and the adrenal-sympathetic system. 



7. HaeckePs law, that ontogeny repeats phylogeny, inter- 

 prets the unique behavior of the human being during child- 

 hood, adolescence, and the adult stage.
