The foundations of physics are problematic, for science is just a refinement of everyday thinking, and scientists are justified in analyzing the nature of everyday thinking. Science is like puzzle solving.

A shift to deductive (logical) thinking frees physics from nineteenth-century false hopes for "induction". The fundamental hypotheses of the theory of relativity have led to an unexpected expansion and broadening of the field theory and superseded the foundations of classical mechanics.

Einstein's generation spends twenty vain years searching for a uniform interpretation of the "quantum character" of systems and phenomena. Quantum mechanics has seized a good deal of the truth and will be a touchstone for a future theoretical basis, but not the starting point for it. The evolution of physics is...
