Sir Bernard Rowland Crick was a British political theorist and democratic socialist whose views were often summarised as "politics is ethics done in public". He sought to arrive at a "politics of action", as opposed to a "politics of thought" or of ideology.
Thought-provoking, certainly. This collection of essays, gathered by Political Quarterly and published in 1970, covered a wide range of subjects within the general theme of political discontent, radicalism and revolution.
It was in places a little dated (naturally, though of course many of the concerns of fifty years ago remain), a little heavy going and impenetrable (I was reminded frequently by the tone/content that I was an interested layperson as opposed to someone with a keen interest in political philosophy), and at times it came over a bit like I was being talked 'at' not 'to' (understandable too) but there was enough in this to keep me amused on a short trip away to the home of municipal socialism.
