An excerpt from an undated letter from BR is found in Structure, Method and Meaning, edited by Paul Henle, Horace M. Kallen and Suzanne K. Langer (New York: Liberal Arts Press, 1951) (B&R B&R H44.1a). The letter is extracted in Horace M. Kallen's Preface, dated 1 Sept. 1950, p. vi.
On learning of the plan for a book to honour Sheffer, BR wrote in a letter, "I have for a large number of years been a great admirer of his work. In particular, his substitution of one undefined term in place of 'or' and 'not' has rendered possible a simplicity in the logic of propositions which had previously been unattainable. I mention this among many other propositions because it was particularly in my province."

Proofread by K. Blackwell
I have for a large number of years been a great admirer of his work. In particular, his substitution of one undefined term in place of “or” and “not” has rendered possible a simplicity in the logic of propositions which had previously been unattainable. I mention this among many other propositions because it was particularly in my province.1
