 Kempf in his book on the vegetative nervous system goes into great detail the way the visceral needs force
the animal or human to satisfy them. Life is a sort of war between the vegetative and the central nervous
system. There is just enough truth in this point of view to make it very entertaining.
Even in the low forms of life instincts are not perfect at the start, or perfect in details, and almost every
member of a species will show individuality in dealing with an obstacle to an instinctive action. In other
words, though there is instinct and this furnishes the basis for action in the lowest forms of life, there is also
the capacity for learning by experience,--and this is Intelligence. "The basis of instinct is heredity and we can
impute an action to pure instinct only if it is hereditary. The other class of actions are those devised by the
individual animal for himself on the basis of his own experience and these are called generally intelligent. Of
intelligence operating within the sphere of instinct there is ample evidence. There are modifications of
instinctive action directly traceable to experience which cannot be explained by the interaction of purely
hereditary tendencies and there are cases in which the whole structure of the instinct is profoundly modified
by the experience of the individual." Hobhouse, whom I quote, goes on to give many examples of instinctive
action modified by experience and intelligence in the insect and lower animal world.
What I wish especially to point out is that man has many instinctive bases for conduct, but instincts as such
are not often seen in pure form in man. They are constantly modified by other instincts and through them runs
