It has been observed many times before that, as yet, there are no
encompassing, integrated theories of mathematical practice available.To
witness, as we currently do, a variety of schools in this field
elaborating their philosophical frameworks, and trying to sort out their
differences in the course of doing so, is also to be constantly reminded
of the fact that a lot of epistemic aspects, extremely relevant to this
task, remain dramatically underexamined. This volume wants to contribute
to the stock of studies filling this perceived lacuna. It contains
papers by established, upcoming, as well as beginning scholars, covering
general, metaphilosophical themes such as naturalism, semiotics,
pragmaticism, or empiricism, next to more specific topics including the
unity of mathematical theories, thruth-flow in mathematics, diagrammatic
reasoning, erroneous argumentation, or numerical analysis.
