And the reason, of course, is that Twin Earth externalism never looked very promising in the mathematical sphere. Therefore, it is not at all implausible that externalism does <I>not</I> affect <I>all</I> of our thoughts, and in particular not our logical and mathematical thoughts. So, if you use such an "un-externalist" example you will not very much impress the more sensible externalist!Joachim Horvathhttps://www.blogger.com/profile/08377048142101247179noreply@blogger.com
