| Il [Penrose] est fondamentalement un platoniste qui croit en un monde unique des idées qui décrivent une réalité physique unique. Moi, au contraire, je suis un positiviste qui croit que les théories physiques ne sont que des modèles mathématiques que nous construisons et qu’il n’y a pas de sens à demander si elles correspondent à la réalité, mais seulement si elles prédisent les observations. |

Theories and models develop over time. Based on data, they undergo a long-term process of testing and refinement before becoming accepted scientific explanations or tools in a given domain. […]
Scientific theories, even when generally accepted after much testing and refinement, are still never complete. Each can be safely applied in some limited domain, some range of situations or conditions for which it has been well tested. Each might also apply in some extended regime where it has yet to be tested, and may have little or nothing to offer in still more distant domains. That is the sense in which no theory can be proven to be true; truth is too complete a notion. We need to emphasize that the incompleteness of theory in no way compromises the stability over time of well-established understanding in science—an important notion that is seldom made explicit. |
