[T]here is an alarmingly wide chasm, I might almost say a vacuum, between the high-brow, who considers reading either as a trade or as a form of intellectual wrestling, and the low-brow, who is merely seeking for gross thrills. It is to be hoped that culture will soon be democratized through some less conventional system of education, giving rise to a new type that might be called the middle-brow, who will consider books as a source of intellectual enjoyment. ["The Nation," Jan, 25, 1912]
