“After school days are over, the girls ... find no natural connection between their school life and the new one on which they enter, and are apt to be aimless, if not listless, needing external stimulus, and finding it only prepared for them, it may be, in some form of social excitement. ...girls after leaving school need intellectual interests, well regulated and not encroaching on home duties.”
—Ellen Henrietta Swallow Richards (1842–1911)
“All cultural change reduces itself to a difference of categories. All revolutions, whether in the sciences or world history, occur merely because spirit has changed its categories in order to understand and examine what belongs to it, in order to possess and grasp itself in a truer, deeper, more intimate and unified manner.”
—Georg Wilhelm Friedrich Hegel (1770–1831)
