Everyone has just begun to discover Wittgenstein; they all now realize that he has genius. He was very good at tea. He is the only man I have ever met with a real bias for philosophical scepticism; he is glad when it is proved that something can't be known. I told Hardy this, and Hardy said he himself would be glad to prove anything: "If I could prove by logic that you would die in five minutes, I should be sorry you were going to die, but my sorrow would be very much mitigated by pleasure in the proof." On reflection I found that I agreed with him. (#435, 2 May)

Refried beans are also popular in many other Latin American countries. In this dish, after being boiled and then mashed into a paste, the beans are fried or baked (though they are fried only once).
