Karl Popper was one of the most important liberal thinkers of the 20th century, as much for his development of an evolutionary understanding of human knowledge as for his more overtly political books.
For an excellent short introduction to his work see the book by Bryan Mageee.
In 1988 Popper took part in three programmes for Channel 4 under the title Uncertain Truth. In the first one he was interviewed by Ernst Gombrich, and by John Eccles and then Anthony Quinton in the next two.
Those programmes are on Youtube. Each is split in two, there are six videos.
When the deaths of Dale Griffin from Mott the Hoople and Glenn Frey from the Eagles followed that of David Bowie, people tweeted things like "I wonder if God is starting a band in Heaven, he's collecting awesome talent from us."
The truth is more mundane. Rock's Golden Age in the 1960s and 1970s was a long time ago and figures from that era have been dying off pretty regularly for a good while now.
My own favourites, the Spencer Davis Group, appear to be the only important British group of the Sixties where all the original members are still alive.
It's just that the extraordinary media attention given to Bowie's passing has made us notice these deaths in the past few weeks.
Anyway, today's choice was going to be a tribute to both Bowie and Dale Griffin - Mott the Hoople singing All the Young Dudes.
But after posting that song I noticed that it had already appeared as a Sunday music video. So here is a different Mott the Hoople song
That's what Guido Fawkes reveals in the Sun today:
You have to feel for the Lib Dems. Wiped out at the ballot box in May and now they are being evicted.
Aides are preparing to leave their HQ at Great George Street after Westminster, one of England’s most Tory councils, gave the go-ahead for plans to turn it into flats. It’s the Tories telling the Lib Dems to pack their bags all over again.
It won't be the council who have given us notice, of course, but the owners of the block. You can read about their plans for this building on New London Development.
Since Liberal Democrat News ceased publication I have not had much reason to visit party headquarters, but Great George Street never appealed to me the way that Cowley Street did. Maybe it was the arms dealers upstairs. Where will we turn up next? Maybe it's time to reread the call from Simon McGrath for party HQ to be moved out of London.
