/There is something similar in Hilbert's letter to Frege on December 29, 1899 (cf. Frege-Hilbert correspondence):
"If in speaking of my points I think of some system of things, e.g. the system: love, law, chimney-sweep... and then assume all my axioms as relation between these things, then my propositions, e.g. Pythagoras' theorem, are also valid for these things."
and he goes on to say:
"All the statements of the theory of electricity are of course also valid for any other system of things which is substituted for the concepts magnetism, electricity..., provided only that the requisite axioms are satisfied."
On January 6 1900, Frege answered:
"Given your definitions, I do not know how to decide the question whether my pocket watch is a point."
