By the pulse of contemporary mathematics I mean the development of the
kind of mathematics relating to Fields Medals: Langlands conjectures,
Weil conjectures, Topological quantum field theory, knot theory, Thurston
on 3-manifolds, Monstrous moonshine, etc., and the extraordinary connections
between these topics. Presumably, we agree that your work on foundations
has no bearing on the way mathematicians view the proper organisation of
mathematical ideas.
Where we may differ is that I believe there is a task for philosophers to
treat
this organisation. In doing so I can appeal beyond Lakatos to Frege and
Plato.
Miles Burnyeat wrote an excellent paper on the role of mathematics in The
Republic. Plato clearly has a sense about the organisation of the whole of
existing mathematics. For the philosopher-king, after 10 years of being
taught math between the ages of 20 and 30, the next 5 years is to be spent
on dialectical discussion, part of the job of which is to question the
founding
assumptions of mathematics, e.g., have we got the definitions of geometry
right?
In many ways the true Platonist of the 20th century is Lakatos - conceptual
development via dialogue.
