From Charles H. Hamm, Mind and Hand, 1886:

It is the most astounding fact of history that education has been confined to abstractions. The schools have taught history, mathematics, language and literature and the sciences to the utter exclusion of the arts, not withstanding the obvious fact that it is through the arts alone that other branches of learning touch human life... In a word, public education stops at the exact point where it should begin to apply the theories it has imparted... At this point the school of mental and manual training combined--the Ideal School--begins; not only books but tools are put in to the hands of the pupil, with this injunction of Comenius; "Let those things that have to be done be learned by doing them."

Also, from Charles H. Hamm:

When it shall have been demonstrated that the highest degree of education results from combining manual with intellectual training, the laborer will feel the pride of a genuine triumph; for the consciousness that every thought-impelled blow educates him, and so raises him in the scale of manhood, will nerve his arm, and fire his brain with hope and courage.

This theory is the antithesis of Plato, from Divine Dialogs:

"...the simplest and purest way of examining things, is to pursue every particular by thought alone, without offering to support our meditation by seeing or backing our reasonings by any other corporal sense."

So much for objective reality!
