John Earman is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand John Earman rather than just read about it. In short: John Earman (born 1942) is an American philosopher of physics. He is an emeritus professor in the History and Philosophy of Science department at the University of Pittsburgh.

Key takeaways

  • John Earman belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect John Earman to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of John Earman from memory before moving on to harder problems.

Reference excerpt

John Earman (born 1942) is an American philosopher of physics. He is an emeritus professor in the History and Philosophy of Science department at the University of Pittsburgh. He has also taught at the University of California, Los Angeles, Rockefeller University, and the University of Minnesota, and was president of the Philosophy of Science Association.

Life and career John Earman was born in Washington, D.C. in 1942. Earman received his PhD at Princeton University in 1968 with a dissertation on temporal asymmetry (titled Some Aspects of Temporal Asymmetry) and it was 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. He remained at Pittsburgh for the rest of his career. Earman is a former president of the Philosophy of Science Association (2001–2002) and a fellow of the American Academy of Arts and Sciences, and of the American Association for the Advancement of Science. He is a member of the Archive Board of the Phil-Sci Archive.

The hole argument

Earman has notably contributed to the debate about the "hole argument". The hole argument was invented for 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 John Earman, John Stachel, and John D. Norton. The trio of Einstein scholars have sometimes been jokingly referred to as John3 = John Norton × John Stachel × John Earman. 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 {\displaystyle d} as the identity function over all elements over the manifold M {\displaystyle M} , excepting a small neighbourhood (topology) H {\displaystyle H} belonging to M {\displaystyle M} . Over H {\displaystyle H} , d {\displaystyle d} comes to differ from identity by a smooth function. With use of this function d {\displaystyle d} we can construct two mathematical models, where the second is generated by applying d {\displaystyle d} to proper elements of the first, such that the two models are identical prior to the time t = 0 {\displaystyle t=0} , where t {\displaystyle t} is a time function created by a foliation of spacetime, but differ after t = 0 {\displaystyle 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.

Worked examples

Example 1 — a first encounter with John Earman

Start with the simplest possible case. Write down what John Earman claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to John Earman before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about John Earman ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of John Earman

In research
John Earman appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses John Earman in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
John Earman is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1942 births, 20th-century American essayists, 20th-century American male writers, so understanding it makes those chapters shorter.
In everyday life
Look for John Earman outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
