Einstein's Sidelights Relativity 23 We ought not..to reject the possibility that the facts comprised in the quantum theory may set bounds to the field theory. 1929Einstein in Nature 2 Feb. 175/1 The purpose of my work is..to reduce to one formula the explanation of the field of gravity and of the field of electromagnetism. For this reason I call it a contribution to ‘a unified field theory’. 1934J. F. Brown in Philos. Sci. I. 325 The central idea of a ‘field’ theory is that the behavior of an object within the field is determined by the field structure or spatial-temporal configuration of the energy within the field. Ibid., By ‘class’ theory I mean essentially what Lewin has called Aristotelian theory, and by ‘field’ theory what Lewin has called Galilean theory. Ibid. 334 Aristotle was trying to answer the question: ‘Why do bodies move?’ Galileo, the first thinker in the field⁓theoretical tradition, attempted the more modest question: ‘How do bodies move?’ 1961M.
