 For some decades, the view that the philosophy of mathematics should take a historical and sociological turn remained restricted to a somewhat marginal school of thought in the philosophy of mathematics. However, in recent years the opposition between this new movement of mathematical practice on the one hand, and ‘mainstream’ philosophy of mathematics on the other hand, is softening. Philosophical questions relating to mathematical practice, the evolution of mathematical theories, and mathematical explanation and understanding have become more prominent, and have been related to more traditional themes from the philosophy of mathematics (Mancosu 2008). This trend will doubtlessly continue in the years to come.
