I am a democratic socialist and I believe that the young Popper worked out, as no one else has ever done, what the philosophical foundations of democratic socialism should be. And like him I would like to see these ideas replace the garbled mixture of Marxism and liberal-minded opportunism which passes for politcal theory on the demoracric left: in 1962 I published a book advocating this in the context of British Labour Party politics called The New Radicalism. In short, while making it clear that Popper is no longer a socialist, I want to claim his ideas for the democratic socialism in which he was so deeply enmeshed when he began to produce them, and in response to whose needs they were produced. This is where I believe their real significance is, and where their future lies. My longest-running argument with the older Popper is about what in my contention is his failure to accept, in matters of practical politics, the radical consequences of his own ideas.
The guiding principle for public policy put forward in The Open Society is: ‘Minimize avoidable suffering’. Characteristically, this has the immediate effect of drawing attention to problems.
