RT Dissertation/Thesis T1 Objectivity with Objects. A Modal Explanation of the Infinite A1 Ordóñez Miguéns, Ismael K1 objectivity K1 fictionalism K1 multiversism K1 abstraction principles K1 potentialism K1 set theory AB The objectivity of mathematics has been questioned for two reasons: Benacerraf’s challengeand the emergence of several limitation theorems in mathematics. This has led to the searchfor new explanations of mathematical knowledge and alternatives to universist platonism.Mainly, mathematical knowledge has been reduced to logical knowledge. Against this,this dissertation argues that mathematical knowledge cannot be reduced to logical knowledge.The two best proposals defending this reduction, fictionalism and multiversism, runinto serious problems. Both will be challenged to explain how mathematical language acquiresits content. Then, it will be argued that they do not satisfy this test. Faced with thisproblem, an alternative explanation of mathematical language and mathematical knowledgewill be developed using abstraction principles. As a result, mathematical knowledge willbe explained through linguistic competence. Finally, the proposal will be applied to ZF settheory.
