For Chalmers, the natural solution to this problem of indexicality is to identify scenarios with centered worlds: ordered tuples of (possible) worlds, individuals, times, and places. According to such a solution, two arbitrary tokens of &#8216;now&#8217; and &#8216;here&#8217; (respectively) have the same primary (or epistemic) intension, picking out the time/place marked at the center of any given scenario. Against this, I will object that there are a posteriori true, i.e. epistemically contingent, utterances of both &#8216;Now = now&#8217; and &#8216;Here = here&#8217;. Since identifying scenarios with centered worlds seems to be the natural solution to the problem of indexicality, this will undermine Chalmers&#8217; two-dimensional semantics.]]></p></abstract>
<abstract abstract-type="short" xml:lang="es"><p><![CDATA[Resumen: Como el propio Chalmers señala, su semántica bidimensional conduce al problema de cómo los escenarios -es decir, los mundos epistémicamente posibles- pueden representar de la mejor manera la información acerca de quién soy, dónde estoy y qué hora es ahora. Para Chalmers, la solución natural a este problema de la indexicalidad consiste en identificar los escenarios con mundos centrados: tuplas ordenadas de mundos (posibles), individuos, tiempos y lugares. Según esta solución, dos casos arbitrarios de &#8220;ahora&#8221; y &#8220;aquí&#8221; (respectivamente) tienen la misma intensión primaria (o epistémica), al designar el tiempo o el lugar marcados en el centro de cualquier escenario dado. Frente a esto, objetaré que hay enunciados de &#8220;Ahora = ahora&#8221; y &#8220;Aquí = aquí&#8221; que son verdaderos a posteriori, es decir, epistémicamente contingentes. Dado que identificar los escenarios con mundos centrados parece ser la solución natural al problema de la indexicalidad, esto socavará la semántica bidimensional de Chalmers.]]></p></abstract>
