¿Está disuelto el puzzle de Frege? Tres objeciones a Howard Wettstein

In this paper I focus my attention on the proposal given by Howard Wettstein in 1980 to the cognitive phenomenon stated by Gottlob Frege in his paper “On sense and reference”. I offer three arguments in order to show that his answer does not weaken this phenomenon. Particularly, I defend three ideas: first, it is legitimate that philosophical semantics, in contrast with what Wettstein defends, provides an answer to the cognitive phenomenon; second, Wettstein does not conceive Frege’s argument correctly by considering it generates a semantic theory from a purely mentalist phenomenon; third, the explanation supplied by Wettstein is assumed by Frege when he states the phenomenon.
