If speculative ideas can not be tested, they're not science; they don't even rise to the level of being wrong.

Einstein has a feeling for the central order of things. He can detect it in the simplicity of natural laws. We may take it that he felt this simplicity very strongly and directly during his discovery of the theory of relativity. Admittedly, this is a far cry from the contents of religion. I don't believe Einstein is tied to any religious tradition, and I rather think the idea of a personal God is entirely foreign to him.

Well, our friend Dirac, too, has a religion, and its guiding principle is "God does not exist and Dirac is His prophet."

It is not only not right, it is not even wrong.

From the point of view of logic, my report on 'Exclusion principle and quantum mechanics' has no conclusion. I believe that it will only be possible to write the conclusion if a theory will be established which will determine the value of the fine structure constant and will thus explain the atomistic structure of electricity, which is such an essential quality of all atomic sources of electric fields actually occurring in nature.

I have done a terrible thing, I have postulated a particle that cannot be detected.

You know, what Einstein has just said isn't so stupid.
