- You mentioned the biography by Pais, Subtle is the Lord: do you find
- this particular objection mentioned in that book? I ask because I
- don't recognize it myself. Pais, rather, emphasizes Einstein's realism.
- By the way, to speak of "philosophical prejudices" is not to trivialize
- Einstein's convictions in any way, but only to emphasize that they were
- not theological.
-
- Here are some relevant passages from Pais:
-
- During the last twenty-five years of life, Einstein maintained that
- quantum mechanics was incomplete. He no longer believed that quantum
- mechanics was wrong but did believe that the common view of the physics
- community was wrong in ascribing to the postulates of quantum mechanics
- a degree of finality that he held to be naive and unjustified. ...
-
- It was in 1935 that Einstein stated his own desiderata for the first
- time in a precise form. This is the criterion of objective reality,
- to which he subscribed for the rest of his life. ...
-
- In contrast to the view [expressed by Bohr] that the concept of
- phenomenon *irrevocably* includes the specifics of the experimental
- conditions of observation, Einstein held that one should seek for
- a deeper-lying theoretical framework which permits the description
- of phenomena independently of these conditions. That is what he meant
- by the term *objective reality*. After 1933 it was his almost solitary
- position that quantum mechanics is logically consistent but that it
- is an incomplete manifestation of an underlying theory in which an
- objectively real description is possible. ...
-
- From this [1933] lecture as well as from discussions with him on the
- foundations of quantum physics, I have gained the following impression.
- Einstein tended to compare the successes of classical mechanics with
- those of quantum mechanics. In his view both were on a par, being
- successful but incomplete. For more than a decade, Einstein had
- pondered the single question of how to extend the invariance under
- uniform translations to general motions. His resulting theory,
- general relativity, had led to only small deviations from Newton's
- theory. (Instances where these deviations are large were discussed
- only much later.) He was likewise prepared for the survival of the
- practical successes of quantum mechanics, with perhaps only small
- modifications. He was also prepared to undertake his own search for
- objective reality, fearless of how long it would take. It is quite
- plausible that the very success of his highest achievement, general
- relativity, was an added spur to Einstein's apartness. Yet it should
- not be forgotten that this trait characterized his entire ouvre and
- style. ...
