The mathematical proof is the most important form of justification in mathematics. It is not, however, the only kind of justification for mathematical propositions. The existence of other forms, some of very significant strength, places a question mark over the prominence given to proof within mathematics. This collection of essays, by leading figures working within the philosophy of mathematics, is a response to the challenge of understanding the nature and role of the proof.
'The two volumes edited by M.Detlefsen without doubt constitute an important and valuable reference for research on the very intricate network of concepts, theories and theses connected with the concept of proof.' - Erkenntnis
