The last thirty years of Einstein's life were largely devoted to a search for a so-called unified field theory that would unify James Clerk Maxwell's theory of electromagnetism with the general theory of relativity, Einstein's theory of gravitation. Einstein's attempt was not successful, and with hindsight we can now see that it was misconceived. Not only did Einstein reject quantum mechanics; the scope of his effort was too narrow. ... Nevertheless Einstein's struggle is our struggle today. It is the search for a final theory.

Quantum mechanics is the most useful and powerful theory physicists have ever devised. Yet today, nearly 90 years after its formulation, disagreement about the meaning of the theory is stronger than ever. New interpretations appear every year. None ever disappear. ... The message from QBism is this: You needn't feel guilty about never getting nervous about this stuff. You were right not to be bothered. But for the sake of intellectual coherence, you had better reexamine what you wrongly may have thought you understood perfectly well about the nature of probability.

A final moral concerns terminology. Why did such serious people take so seriously axioms which now seem so arbitrary? I suspect that they were misled by the pernicious misuse of the word ‘measurement' in contemporary theory. This word very strongly suggests the ascertaining of some preexisting property of some thing, any instrument involved playing a purely passive role. Quantum experiments are just not like that, as we learned especially from Bohr. The results have to be regarded as the joint product of ‘system' and ‘apparatus,' the complete experimental set-up.

When a war of annhilihation is surely though in point of time indefinately impending over a weaker state, the wiser, more resolute and more devoted men who would immediately prepare it for the unnavoidable struggle and thus cover their defensive policy with a strategy of offense always find themselves hampered by the indolent, cowardly mass of the money worshippers, of the aged and feeble, and the thoughtless who are minded merely to gain time to live and die in peace and to postpone and any price the final struggle.

'Party,' in the general vocabulary of world intellectuals, is basically a unified social organization with a 'world-view,' an 'Ideology,' a 'philosophy of history,' and 'ideal social order,' a 'class foundation,' a 'class orientation,' a 'social leadership,' a 'political philosophy,' a 'political orientation,' a 'tradition,' a 'slogan,' a 'strategy,' a "tactic of struggle," and ... a "hope" that wants to change the "status quo" in man, society, people, or a particular class, and establish the "desired status" in its stead.

Even a statement very close to the periphery can be held true in the face of recalcitrant experience by pleading hallucination or by amending certain statements of the kind called logical laws. Conversely, by the same token, no statement is immune to revision. Revision even of the logical law of the excluded middle has been proposed as a means of simplifying quantum mechanics; and what difference is there in principle between such a shift and the shift whereby Kepler superseded Ptolemy, or Einstein Newton, or Darwin Aristotle?
