This fresh and timely book argues that we can detach Marx the critic of current society from Marx the prophet of future society, and that he remains the most impressive critic we have of liberal, capitalist, bourgeois society. Wolff also shows that the value of the 'great thinkers' does not depend on their views being true, but on other features such as their originality, insight, and systematic vision. For these reasons, and more, Wolff shows us why Marx still richly deserves to be read.
