I wrote: 1. From the preface or the introduction to the Grundgesetze: Frege's report of his own reaction upon learning from Russell of the paradox of class membership. The paradox showed that Frege's Rule V was untenable, and his project of establishing mathematics on a foundation of logic was doomed. I now realize that this could not be right, for the Grundgesetze was published in two volumes, and Russell's discovery wasn't acknowledged until Volume II was about to go to press. So this would be from an appendix or a postscript to it.
