The philosophy of mathematics is an extremely challenging, in terms of interest, scientific field with special requirements, which presupposes knowledge of philosophy and knowledge of mathematics.

This translated book by M. Friend consists of six chapters that refer to the basic currents of the philosophy of mathematics with particular reference to mathematical concepts, such as the concept of infinity, and to fundamental philosophical disputes, such as that between mathematical realism and constructivism.

It is an important international contribution to the field, which combines and balances the philosophical with the technical mathematical level.

It explains the subtle conceptual differences, insists on understanding quite technical and sophisticated philosophical or logical and mathematical concepts, and teaches the reader with a flowing, direct, and lively speech.
