Human education is concerned with certain changes in the intellects, characters and behavior of men, its problems being roughly included under these four topics: Aims, materials, means and methods.

Psychology is the science of the intellects, characters and behavior of animals including man.

Human folk are as a matter of fact eager to find intelligence in animals.

Human beings are accustomed to think of intellect as the power of having and controlling ideas and of ability to learn as synonymous with ability to have ideas. But learning by having ideas is really one of the rare and isolated events in nature.

Just as the science and art of agriculture depend upon chemistry and botany, so the art of education depends upon physiology and psychology.

It will, of course, be understood that directly or indirectly, soon or late, every advance in the sciences of human nature will contribute to our success in controlling human nature and changing it to the advantage of the common weal.
