John Norton: "Einstein could not see how to formulate a fully
relativistic electrodynamics merely using his new device offield
transformations. So he considered the possibility of modifying
Maxwell's electrodynamics in order to bring it into accord with an
emission theory of light, such as Newton had originally conceived.
There was some inevitability in these attempts, as long as he held to
classical (Galilean) kinematics. Imagine that some emitter sends out a
light beam at c. According to this kinematics, an observer who moves
past at v in the opposite direction, will see the emitter moving at v
and the light emitted at c+v. This last fact is the defining
characteristic of an emission theory of light: the velocity of the
emitter is added vectorially to the velocity of light emitted....If an
emission theory can be formulated as afieldtheory, it would seem to
be unable to determine the future course of processes from their state
in the present. AS LONG AS EINSTEIN EXPECTED A VIABLE THEORY LIGHT,
ELECTRICITY AND MAGNETISM TO BE AFIELDTHEORY, these sorts of
objections would render an EMISSION THEORY OF LIGHT INADMISSIBLE."

Albert Einstein: "I consider it entirely possible that PHYSICS CANNOT
BE BASED UPON THEFIELDCONCEPT, that is on continuous structures.
Then NOTHING WILL REMAIN of my whole castle in the air, including the
theory of gravitation, but also nothing of the rest of contemporary
physics."

Louis de Broglie: "Tout d'abord toute idée de grain se trouvait
expulsée de la théorie de la Lumière : celle-ci prenait la forme d'une
théorie du champ où le rayonnement était représenté par une
répartition continue dans l'espace de grandeurs évoluant continûment
au cours du temps sans qu'il fût possible de distinguer, dans les
domaines spatiaux au sein desquels évoluait le champ lumineux, de très
petites régions singulières où le champ serait très fortement
concentré et qui fournirait une image du type corpusculaire. Ce
caractère à la fois continu et ondulatoire de la lumière se trouvait
prendre une forme très précise dans la théorie de Maxwell où le champ
lumineux venait se confondre avec un certain type de champ
électromagnétique."

Lee Smolin: "It is also disappointing that none of the biographers
mention the writings that lead John Stachel, the founding editor of
the Einstein Papers project, to speak of "the other Einstein." These
writings look beyond his struggles with the unified field theory to
"the other possibility [which] leads in my opinion to a renunciation
of the space-time continuum..."

Do all those honest biographers have a serious reason to avoid "the
other Einstein" problem? Something to do with "NOTHING WILL REMAIN of
my whole castle in the air, including the theory of gravitation, but
also nothing of the rest of contemporary physics"?
