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.
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.
This growth in the number, speed of formation, permanence, delicacy and complexity of associations possible for an animal reaches its acme in the case of man.
To the intelligent man with an interest in human nature it must often appear strange that so much of the energy of the scientific world has been spent on the study of the body and so little on the study of the mind.
When, instead of merely associating some act with some situation in the animal way, we think the situation out, we have a set of particular feelings of its elements.
