The Long Revolution is a book of parts of variable value. Its first part is largely theoretical, but the theory is largely Williams's own, with little discussion of other theories of the concepts it addresses - the creative mind, culture, the individual and society. The conceptual vocabulary is quite impoverished and there is too much reliance on the concept of 'experience', which after a while becomes inadequate to his purposes. Overall the first part is a bit of a slog, with the exception of a brief but interesting excursion on the English novel in the 1840s.
The second part is altogether more interesting, as a detailed account of the history of different cultural forms - the novel, the drama, the newspaper and periodical. However, these quantitative and empirical accounts can tend towards the overly descriptive. I, at any rate, found myself wanting more analysis of the meaning and morphology of the themes and subject matter these forms were used to address. That said, there are still interesting points made throughout this part - for instance, Williams's explanation for the extraordinary achievements of Elizabethan drama.
Both the first and second parts clearly represent the beginning of a new form of cultural analysis, combining both sociology and literary criticism of an impressively broad scope. The narrowness of its theoretical horizons is more a testimony to the intellectual environment of Britain in the 1950s than to Williams himself, who later went on to do work of greater theoretical depth informed by engagement with Marxism, and especially the work of Gramsci, in the 1970s.
The final section, 'Britain in the 1960s' is dated now, but still quite interesting in some respects. It is striking to see how early Williams was calling for constitutional reform, cultural and industrial democracy, and more internal party democracy - a demand that has still gone largely unmet today. If I disagree with the detail of some of his proposals, it seems clear that he was one of the first British left intellectuals to articulate, in outline at least, what must still remain the substance of any socialist movement's political programme, if it aspires not just to temporarily improve people's lives, but achieve a durable new working class hegemony.
