Spe Salvi - Part 21 - Pope Benedict XVI
True, Marx had spoken of the interim phase of the dictatorship of the proletariat as a necessity which in time would automatically become redundant. This “intermediate phase” we know all too well, and we also know how it then developed, not ushering in a perfect world, but leaving behind a trail of appalling destruction. Marx not only omitted to work out how this new world would be organized—which should, of course, have been unnecessary. His silence on this matter follows logically from his chosen approach. His error lay deeper. He forgot that man always remains man. He forgot man and he forgot man's freedom. He forgot that freedom always remains also freedom for evil. He thought that once the economy had been put right, everything would automatically be put right. His real error is materialism: man, in fact, is not merely the product of economic conditions, and it is not possible to redeem him purely from the outside by creating a favourable economic environment.
