The Origin and Nature of Emotions HTML version
application of a stimulus are allowed complete rest for a certain
number of hours, *without sleep, the characteristic histologic
appearance of exhaustion in the brain, adrenals, and liver is not
altered notably, whereas in animals allowed to sleep for the same
number of hours the histologic changes in these organs are
lessened— in some cases obliterated even.
This significant phenomenon and its relation will be dealt with in a
Many of the arguments and illustrations by which the primary
premises were established are repeated—a few in all—many in
more than one of these addresses. It will be observed, however,
that the APPLICATION of these premises varies, and that their
SIGNIFICANCE broadens progressively.
In the Ether Day Address the phylogenetic key supplied by Darwin
was utilized to formulate the principle that the organism reacts as a
unit to the stimuli of physical injury, of emotion, of infection, etc.
To the study of these reactions (transformations of energy) the
epoch-making work of Sherrington, "The Integrative Action of the
Nervous System," gave an added key by which the dominating role
of the brain was determined. Later the original work of Cannon on
the adrenal glands gave facts, and an experimental method by
which Darwin's phylogenetic theory of the emotions was further
elaborated in other papers, especially in the one entitled
"Phylogenetic Association in Relation to the Emotions," read
before The American Philosophical Society in April, 1911.
