If we do not want to believe that ideas are innate
or God-given, but the result of subjective
thinkers' conceptual activity, we have to devise a
model of how elementary mathematical ideas
could be constructed – and such a model will be
plausible only if the raw material it uses is itself
not mathematical.
(Ernst von Glasersfeld)

number (infinite instances) represented.
Instead, we have procedures to
operate with them. So whenever I face a
number symbol, I know what can be done
with it.
