I forget who it was who said that Russell was a good mathematician and a poor philosopher. I’d suggest a qualification and an addition: his contribution to the philosophy of science stands up pretty well but his contribution to politics was always dreadful. And in his role as the philosophical grandfather of Willard Van Orman Quine I had more than one occasion to curse his memory while battling through Philosophical Logic at Oxford. As for his typically dreadful political statements in the late 1960s, all I have to say is that I hope I am that lucid in my late 90s.
