Murderous certainty

I can’t claim that there is much of connection between this post and the themes of my book, with which this blog is supposed to be concerned, but at the moment I can’t think of much else except the Charlie Hebdo massacre in Paris. Like almost everyone else I am shocked and revolted by it. Above and beyond the shock and revulsion that would accompany any such event, what is particularly disgusting is that it was an attack on free expression, which is central to democracy and to a free society.
