"In 1903 there appeared Problems of Idealism, a collection of essays many of whose authors had recently been Marxists, but which condemned Marxism and materialism for their moral nihilism, contempt of personality, determinism, and fanatical pursuit of social values regardless of the individuals who made up society; they also attacked Marxism for its uncritical worship of progress and sacrifice of the present to the future. (pp. 420-1)"
