J. Gresham Machen was prophetic about many things. His insight into ideas and their consequences made him stunningly precient. Even so, it is difficult to believe that he could have the foresight to write this--and in 1923 no less!
"When one considers what the public schools of America in many places already are--their materialism, their discouragement of any sustained intellectual effort, their encouragement of pseudo-scientific fads of experimental psychology--one can only be appalled by the thought of a commonwealth in which there is no escape from such a soul-killing system."
Wow! May God have mercy on us--nearly a century on.
