Moore’s health was quite good in 1946-7, but before that he had suffered a stroke and his doctor had advised that he should not become greatly excited or fatigued. Mrs. Moore enforced this prescription by not allowing Moore to have a philosophical discussion with anyone for longer than one hour and a half. Wittgenstein was extremely vexed by this regulation. He believed that Moore should not be supervised by his wife. He should discuss as long as he liked. If he became very excited or tired and had a stroke and died—well, that would be a decent way to die: with his boots on.
