[Solipsism is] a theme that was important for Russell throughout his writings. In fact, in some of his works he famously mentions his encounters with Ladd-Franklin, hinting at a difference of opinions and her inability to see the inconsistency in what she claimed.

This article aims to show what really transpired as evidenced by the letters, of which seven of the extant eleven are reproduced in full with annotations.
