Look, I'm not being 'sensitive', it's just that I've made that statement and repeated it twice already, and then you go and ask the same sort of question. Read the thread, plain and simple.
Unless the 'sensitive' thing was directed at my response to your phone 'joke', in which case sorry, but it was pretty retarded. =/
No one is suggesting you trust a mirror on a philosophical level. Just trust it on an electromagnetic level.
Since you use a mirror to comb your hair I'm guessing you do.
Here's the first line of my original post, back on page 1:
Philosophically, it makes perfect sense to assume that the Earth is flat based on its appearance.
If you're not suggesting I trust it on a philosophical level, then what exactly have you been challenging all this time?
So, in summary:
Philosophically trust nothing I am told. Scientifically I can trust things I am told.
Philosophically trust no pictures you are shown. Scientifically I can trust pictures I am shown.
Philosophically trust nothing you read in a book. Scientifically I can trust factual information in a book.
Philosophically I can't trust that the moon in the telescope view hole is the same moon that is in the sky. Scientifically I can trust that the moon in the tescope view hole is the same moon that is in the sky.
Philosophically the internet does not exist. Scientifically it does.
Philosophically the entirety of the earth at this moment must consist of cubicle walls surrounded at their perimeter by tinted glass which is surrounded by roads other buildings and a few trees. Scientifically I know that it isn't.
Philosophically the earth must be flat. Scientifically the earth is spherical.
Which one should I choose?
Philosophically is like the band at a college football game of science. Yeah they can make some noise when their team scores or makes a big play, and when the football teams are taking a break they provide some entertianment while nothing else is going on. They are not as good to look at as the cheerleaders and in all reality could be substituted with a PA system as the bulk of the crowd is there for football.
