The celu of the philosophical literature on the hole argument is the 1987 paper by Earman & Norton [What Price Space-time Substantivalism? The Hole Story Br. J. Phil. Sci.]. This paper has a well-known back-story, concerning work by Stachel and Norton on Einsteins thinking in the years 1913-15. Less well-known is a connection between the hole argument and Earmans work on Leibniz in the 1970s and 1980s, which in turn can be traced to an argument first presented in 1975 by Howard Stein. Remarkably, this thread originates with a misattribution: the argument Earman attributes to Stein, which ultimately morphs into the hole argument, was not the argument Stein gave. The present paper explores this episode and presents some reflections on how it bears on the subsequent literature.
We address a recent proposal concerning surplus structure due to Nguyen et al. [Why Surplus Structure is Not Superfluous. Br. J. Phi. Sci. Forthcoming.] We argue that the sense of surplus structure captured by their formal criterion is importantly di
A Norton algebra is an eigenspace of a distance regular graph endowed with a commutative nonassociative product called the Norton product, which is defined as the projection of the entrywise product onto this eigenspace. The Norton algebras are usefu
Typicality arguments attempt to use the Copernican Principle to draw conclusions about the cosmos and presently unknown conscious beings within it. The most notorious is the Doomsday Argument, which purports to constrain humanitys future from its cur

Hideki Yukawa, Sin-itiro Tomonaga and Shoichi Sakata pioneered nuclear and particle physics and left enduring legacies. Their friendly collaboration and severe competition laid the foundation to bring up the active postwar generation of nuclear and p
