To rescue "degraded" Marxism from the Marxists and anti-Marxists is a valuable service. To save it from Marx and Engels is harder. But, helped by Hegel, Harrington is always absolutely clear about why he believes he knows what Marx really meant. Then his Marxism-not monistic, deterministic or altogether materialistic-is used to produce a "secret history" of the capitalist crisis of the 1970s that is less original than the rest of this stimulating work.
