"Si
uno se pregunta, abstracción hecha de la mecánica cuántica, qué es lo
característico del mundo de ideas de la física, uno se halla ante todo
marcado por lo siguiente: los conceptos de la física hacen referencia a
un mundo real existente, es decir, las ideas se establecen en relación a
cosas tales como cuerpos, campos, etcétera, los cuales reivindican una
"existencia real" o sea independiente del sujeto que las percibe. Es
además característico de de estos objetos físicos el que, con
independencia del pensamiento, se hallan ordenados en un continuo
espacio temporal. Un aspecto esencial de esta ordenación de las cosas
en física es que pueden reclamar, en un momento determinado, una
existencia independiente del otro, con tal de que estos objetos se
hallen 'situados en diferentes partes del espacio'. A menos de hacer
propia esta asunción relativa a la independencia de la existencia de
objetos que están suficientemente alejados el uno del otro (...) el
pensar de la física en el sentido usual del término no es posible (...).
La relativa independencia de objetos (A B) suficientemente alejados
puede expresarse mediante la siguiente idea: una externa influencia en
A carece de interna influencia en B; esto es conocido como el principio
de localidad (...) Si este axioma llegara a ser abolido (...) la
postulación de leyes que podrían ser verificadas empíricamente en el
sentido aceptado del término, sería imposible" .[1]

"If one asks what, irrespective of quantum mechanics, is characteristic of the world of ideas of physics, one is first of all struck by the following: the concepts of physics relate to a real outside world, that is, ideas are established relating to things such as bodies, fields, etc., which claim a "real existence" that is independent of the perceiving subject [...]". It is further characteristic of these physical objects that they are thoughtless arranged in a space-time continuum. An essential aspect of this arrangement of things in physics is that they may claim, at a certain time, to an existence independent of one another, provided these objects ‘are situated in different parts of space'. Unless one makes this kind of assumption about the independence of the existence of objects which are far apart from one another in space [...].physical thinking in the familiar sense would not be possible [...]". The following idea characterizes the relative independence of objects far apart in space (A and B): external influence on A has no direct influence on B; this is known as the "principle of locality" [...]. If this axiom were to be [...] abolished [...] the postulation of laws which can be checked empirically in the accepted sense, would become impossible"
