Among other statements, Einstein suggested the abandonment of Maxwell's electrodynamics with the following:
"Today, however, we must consider the hypothesis of ether as an obsolete standpoint. It cannot even be denied that there is a large class of facts concerning radiation which show that light is endowed with certain properties which can far easier be understood from the standpoint of Newton's emission theory than from the standpoint of the undulation theory. Therefore, it is my opinion that the next step in the development of theoretical physics will bring us a theory of light which must be conceived as some sort of fusion between emission and undulation theory. The following statements are intended to give reason to this opinion and to show that a deep change of our intuitions into the essence and nature of light is unavoidable."
