## "Evolution of the Platonic workshop:

the manufacture of new mathematical entities"

One way of narrating the history of mathematics is by plotting against time the range
of entities that make up the subject matter of mathematics at any given stage. New
entities can arise from demands made on mathematics from outside, or from the growth of mathematics itself. Entities arising in the second way are much more likely to be problematic.
