In a moment of doubt about the socialist record Eric Hobsbawm once wrote: 'If the left have to think more seriously about the new society, that does not make it any the less desirable or necessary or the case against the present one any less compelling.'1 There, in a nutshell, is the sum of the New Left's commitment. We know nothing of the socialist future, save only that it is both necessary and desirable. Our concern is with the 'compelling' case against the present, which leads us to destroy what we lack the knowledge to replace.
