“But then, the Manifesto – and this is not the least of its remarkable qualities – is a document which envisaged failure. It hoped that the outcome of capitalist development would be ‘A revolutionary reconstitution of society at large’ but, as we have already seen, it did not exclude the alternative: ‘common ruin’. Many years later, another Marxian rephrased this as the choice between socialism and barbarity. Which of these will prevail is a question which the twenty-first century must be left to answer”. (in introduction to the Manifesto).
