Researchers at the University of Edinburgh recently discovered a letter written by Albert Einstein in which Einstein writes that his theories were inspired by the 18th Century (subjectivist) philosopher, David Hume.

Here is an excerpt from Einstein’s letter:

You have correctly seen that this line of thought was of great influence on my efforts and indeed Ernst Mach and still much more Hume, whose treatise on understanding I studied with eagerness and admiration shortly before finding relativity theory…. It is very possible that without these philosophical studies I can not say that the solution would have come.

Hume definitely was not an Objectivist.

I am not endorsing Hume. I am trying to stimulate discussion similar to what Hugh Akston might have had with his star students Galt, D'Anconia, and Danneskjold.
