Harris was associated with Amos Bronson Alcott's Concord School of Philosophy from 1880 to 1889, when he became U.S. Commissioner of Education, serving until 1906. He did his best to organize all phases of education on the principles of philosophical pedagogy as espoused by Hegel, Kant, Fichte, Fröbel, Pestalozzi and many others of idealist philosophies.
