My own feeling is that one should refuse to participate in any activity that implements American aggression - thus tax refusal, draft refusal, avoidance of work that can be used by the agencies of militarism and repression, all seem to me essential.

My memory - faded, as I say - is that Paul Johnson was trying to vilify all intellectuals who were at all critical of the states he worships, and of power generally (except, of course, the power of enemies, which we must denounce, imitating the commissars who are his models, though he doesn't understand it).

In the primary debates for the 2016 election, every single Republican candidate was a climate change denier, with one exception, John Kasich - the "rational moderate" - who said it may be happening but we shouldn't do anything about it. For a long time, the media have downplayed the issue.

Don't be obsessed with tactics but with purpose. Tactics have a half life.

I have no Facebook page or Twitter - I don't participate in it, and I don't like it particularly. I mean, it's a form of interaction, which strikes me as extremely superficial.

I also learned from reading the left-wing press about the [Franklin] Roosevelt administration's indirect support for Francisco Franco, which was not well known, and still isn't.

We have to be a little cautious about not trying to kill a gnat with an atom bomb. The performances are so utterly absurd regarding the "post-truth" moment that the proper response might best be ridicule.
