A paper by Tomasz Mróz titled Letters of Bertrand Russell and Wincenty Lutosławski on Immortality, Matter and Plato was published in “Russell. The Journal of Bertrand Russell Studies” (1, vol. 40, 2020, pp. 27-42; DOI: https://doi.org/10.15173/russell.v40i1.4417).
The paper presents letters between Wincenty Lutosławski and Bertrand Russell, but what seems to be the most interesting regarding AΦR are the post-war letters on Russell’s History of Western Philosophy, for despite their different philosophical positions, Lutosławski’s opinion on this work as a whole was favourable, in particular the chapters on Plato. Such an assessment was the exception rather than the rule for that book, and knowing Lutosławski’s general recognition in Platonic studies, Russell forwarded the letter to his publisher.
