"I have a problem. You may recollect that in 1969 we raised with Lord Russell the possibility of adding to Human Knowledge an edited version of the notes that he had compiled and which were not at the time included, as he half wished, in My Philosophical Development, but which now exist in manuscript at McMaster and have been looked at and edited by Professor Jack Pitt." "... I would like to find out whether, in principle, those who look after Lord Russell's affairs like the idea of this new edition edited by Professor Pitt and whether they would like to look it over to see whether Professor Pitt has done a good job."
