Biography

John Earman was born in Washington, D.C. in 1942 and earned his Ph.D. at Princeton University in 1968 with a dissertation on temporal asymmetry directed by Carl Gustav Hempel and Paul Benacerraf. After holding professorships at UCLA, the Rockefeller University, and the University of Minnesota, he joined the faculty of the History and Philosophy of Science department of the University of Pittsburgh in 1985.[2] He remained at Pittsburgh for the rest of his career, recently retiring to become Professor Emeritus. Earman is a former president of the Philosophy of Science Association and a fellow of the American Academy of Arts and Sciences, and of the American Association for the Advancement of Sciences.[3] He is a member of the Archive Board of the Phil-Sci Archive.[4]

The hole argument

Earman has notably contributed to debate about the "hole argument". The hole argument was invented for slightly different purposes by Albert Einstein late in 1913 as part of his quest for the general theory of relativity (GTR). It was revived and reformulated in the modern context by John3 (a short form for the "three Johns": John Earman, John Stachel, and John Norton).

With the GTR, the traditional debate between absolutism and relationalism has been shifted to whether or not spacetime is a substance, since the GTR largely rules out the existence of, e.g., absolute positions. The "hole argument" offered by John Earman is a powerful argument against manifold substantialism.

This is a technical mathematical argument but can be paraphrased as follows:

Define a function d as the identity function over all elements over the manifold M, excepting a small neighbourhood (topology) H belonging to M. Over H, d comes to differ from identity by a smooth function.

With use of this function d we can construct two mathematical models, where the second is generated by applying d to proper elements of the first, such that the two models are identical prior to the time t=0, where t is a time function created by a foliation of spacetime, but differ after t=0.

These considerations show that, since substantialism allows the construction of holes, that the universe must, on that view, be indeterministic. Which, Earman argues, is a case against substantialism, as the case between determinism or indeterminism should be a question of physics, not of our commitment to substantialism.
