The restriction of studies of human intellect and character to studies of conscious states was not without influence on a scientific studies of animal psychology.

There is no reasoning, no process of inference or comparison; there is no thinking about things, no putting two and two together; there are no ideas - the animal does not think of the box or of the food or of the act he is to perform.

The un-conscious distortion of the facts is almost harmless compared to the unconscious neglect of an animal's mental life until it verges on the unusual and marvelous.
