There are brains so large that they unconsciously swamp all individualities which come in contact or too near, and brains so small that they cannot take in the conception of any other individuality as a whole, only in part or parts.
The brain is the palest of all the internal organs, and the heart the reddest. Whatever comes from the brain carries the hue of the place it came from, and whatever comes from the heart carries the heat and color of its birthplace.
Individuals possessing moderate-sized brains easily find their proper sphere, and enjoy in it scope for all their energy. In ordinary circumstances they distinguish themselves, but they sink when difficulties accumulate around them. Persons with large brains, on the other hand, do not readily attain their appropriate place; common occurrences do not rouse or call them forth.
