"At the present time the main question is whether a field theory of the kind here contemplated can lead to the (*Unified Field) goal at all. By this is meant a theory that describes exhaustively physical reality, including four dimensional space, by a field.

"The present day generation of physicists is inclined to answer this questiion in the negative. In conformity with the present form of the quantum theory it believes that the state of a system cannot be specified directly, but only in an indirect way by a statement of the statistics of the results of measurements attainable on the system. The conviction prevails that the experimentally assured duality (corpuscular particle and wave structure) can be realized only by such a weakening of the concept of reality. I think that such a far reaching theoretical renunciation is not for the present justified by our actual knowledge, and that one should not desist from pursuing to the end path of the relativistic field theory." - Albert Einstein, Ideas & Opinions, Last page, last paragraph, last sentence, p. 377
