  The chapter advances a reformulation of the classical problem of the nature
of mathematical objects (if any), here called "Plato's problem," in line with
the program of a philosophy of mathematical practice. It then provides a sketch
of a platonist solution, following the same perspective. This solution
disregards as nonsensical the question of the existence of abstract, and
specifically mathematical, objects, by rather focusing on the modalities of our
access to them: objects (in general, both concrete and abstract) are regarded
as individual contents that we have (or can have) a de re epistemic access to.
The question of the existence of mathematical objects is then replaced by that
of the modalities of our de re epistemic access to individual mathematical
contents.
