forum for week of 26 September: skepticism

I believe that a lot of people intentionally choose not to argue against philosophical skeptics not only because their theory isn't falsifiable, but also because the theory has very little impact on people's lives. the "fact" that 2+3=5 may not be true, but at least this reality, 2+3 always seems to be 5 to everyone. because of this consistency, the world is able to function with no problem regardless of how true our knowledge(which may be a giant interconnection of wrongness) is. In a way, this is an attitude similar to that of an externalist's since it is like arguing that what really matters is the end result, in which case would be the functioning of the world, rather than the process of getting to the end result.
