1920s–1950s, 4D Timelock (1928)
Context: There will come a time when the proper education of children, by a glorified system of spontaneous education of choice, similar to the Montessori System, will be made possible. Children, as well as grown-ups, in their individual, glorified, drudgery-proof homes of Labrador, the tropics, the Orient, or where you will, to which they can pass with pleasure and expedition by means of ever-improving transportation, will be able to tune in their television and radio to the moving picture lecture of, let us say, President Lowell of Harvard; the professor of Mathematics of Oxford; of the doctor of Indian antiquities of Delhi, etc. Education by choice, with its marvelous motivating psychology of desire for truth, will make life ever cleaner and happier, more rhythmical and artistic.
