Pierre Duhem frasi celebri

“Certo, io credo pienamente nelle verità rivelateci da Dio e trasmessaci dalla sua Chiesa, non ho mai nascosto la mia fede e Colui nel quale la ripongo mi salvaguarderà, lo spero nel profondo del cuore, dall'arrossirne. In questo senso è lecito affermare che la fisica da me professata è quella di un credente.”

Pierre Duhem

citato in Louis De Broglie, La vita e l'opera di Pierre Duhem

“Alla costruzione di questo sistema [la teoria del Grande Anno] contribuirono tutti i discepoli della filosofia ellenica – peripatetici, stoici, neoplatonici –; a questo sistema Abu Masar offrì l'omaggio degli Arabi; i rabbini più illustri, da Filone di Alessandria a Maimonide, l'avevano accettato. Per condannarlo e gettarlo a mare come una mostruosa superstizione, dovette venire il cristianesimo.”

“Ora queste due domande – Esiste una realtà materiale distinta dall'apparenza sensibile? e Qual è la natura della realtà? – non hanno la loro origine nel metodo sperimentale, che è conosciuto solo attraverso l'apparenza sensibile e non può scoprire nulla al di là di essa. La risoluzione di queste domande trascende i metodi utilizzati dalla fisica; è l'oggettto della metafisica.
Pertanto, se lo scopo delle teorie fisiche è spiegare le leggi sperimentali, la fisica teorica non è una scienza autonoma; essa è subordinata alla metafisica.”

Pierre Duhem: Frasi in inglese

“The first question we should face is: What is the aim of a physical theory? To this question diverse answers have been made, but all of them may be reduced to two main principles:
"A physical theory," certain logicians have replied, "has for its object the explanation of a group of laws experimentally established."
"A physical theory," other thinkers have said, "is an abstract system whose aim is to summarize and classify logically a group of experimental laws without claiming to explain these laws…
Now these two questions — Does there exist a material reality distinct from sensible appearances? and What is the nature of reality? — do not have their source in experimental method, which is acquainted only with sensible appearances and can discover nothing beyond them. The resolution of these questions transcends the methods used by physics; it is the object of metaphysics.
Therefore, if the aim of physical theories is to explain experimental laws, theoretical physics is not an autonomous science; it is subordinate to metaphysics…
Now, to make physical theories depend on metaphysics is surely not the way to let them enjoy the privilege of universal consent.”

“There you have, then, a theoretical physics which is neither the theory of a believer nor that of a nonbeliever, but merely and simply a theory of a physicist; admirably suited to classify the laws studied by the experimenter, it is incapable of opposing any assertion whatever of metaphysics or of religious dogma, and is equally incapable of lending effective support to any such assertion.”

“The one who contributed most to break down the barrier between physical method and metaphysical method, and to confound their domains, so clearly distinguished in the Aristotelian philosophy, was surely Descartes.”

“Every time people cite a principle of theoretical physics in support of a metaphysical doctrine or physical dogma, they commit a mistake, for they attribute to this principle a meaning not its own, an import not belonging to it.”

“Now, a symbol is not, properly speaking, either true or false; it is, rather, something more or less well selected to stand for the reality it represents, and pictures that reality in a more or less precise, or a more or less detailed manner.”
