In section 1 I discuss some arguments suggested by Dummet's work, aimed to support the claim that the real problem between realism and antirealism is one about the meaningfulness of sentences. I give sorne reasons to consider them less than conclusive, and to mantain the importance of the traditional approach in terms of the nature of the referred objects. In section 2 I give an account of Frege's view on the objectivity of arithmetic and its relationship with the objectivity of numbers. I defend the possibility of a partially constructivistic interpretation of Frege's analysis. In section 3 Husserl's criticisms of Frege are summed up. I claim that they are not efficient in their original version but it is also suggested that the objections can be rephrased in such a way that they come closer to Benacerraf's criticism on Platonismo An abstractionist altemative, connected with the Erlangen Program, is examined. According to what was said in section 2, it is suggested that even though Frege's view is still unsatisfactory, it is not refuted and the abstractionist view is even weaker.

Todos hemos estudiado que los números tienen un cierto valor simbólico, tanto en Pitágoras como en la Biblia. Concretamente, en la Biblia el número 40 tiene una especial presencia: aparece en más de cien ocasiones y, de alguna manera, expresa los límites de un tiempo en el que se realiza una tarea importante. Así, Jesucristo está 40 días en el desierto y 40 días tras la resurrección, y en el Antiguo Testamento el diluvio duró 40 días e Israel peregrinó durante 40 años hasta alcanzar la tierra prometida. We have all learned that numbers have a certain symbolic value, both in Pythagoras and in the Bible. Specifically, the number 40 has a special presence in the Bible: it appears more than one hundred times and, in a way, expresses the limits of a period of time in which an important task is carried out. Thus, Jesus Christ spent 40 days in the desert and 40 days after the resurrection, and in the Old Testament the flood lasted 40 days and Israel wandered for 40 years before reaching the promised land.
