“The best hopes of any community rest upon that class of its gifted young men who are not encumbered with large possessions.... I now speak of extensive scholarship and ripe culture in science and art.... It is not large possessions, it is large expectations, or rather large hopes, that stimulate the ambition of the young.”
—Rutherford Birchard Hayes (1822–1893)
“I am beginning to suspect all elaborate and special systems of education. They seem to me to be built up on the supposition that every child is a kind of idiot who must be taught to think.”
—Anne Sullivan (1866–1936)
