So the animal finally performs in that situation only the fitting act.

All that exists, exists in some amount and can be measured.

Dogs get lost hundreds of times and no one ever notices it or sends an account of it to a scientific magazine.

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.

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.

Amongst the minds of animals that of man leads, not as a demigod from another planet, but as a king from the same race.

Whatever exists at all exists in some amount. To know it thoroughly involves knowing its quantity as well as its quality.
