Default Re: Evidence and all that

I'm trying to clear up some of the recuring issues about evidence.

Propositon E.
Suppose two theories T1 and T2 do not make different predictions about the world. Then deciding whether to believe T1 or T2 is nothing to do with evidence.

[/ QUOTE ]



Consider
T1: It has never been possible to get to Narnia thorough my bedroom wardrobe.
T2: It was possible to get to Nrania through my wardrobe between 2200-2300 GMT on 15 December 2005.

By proposition E, deciding between T1 and T2 is not a matter of evidence.

Therefore anyone who believes that there has never been a link between my bedroom wardrobe and Narnia doesn't believe this because of the evidence.

Note I am fairly sure no one inspected my bedroom wardrobe between 2200-2300 GMT on 15 December 2005.

Precisely. (assuming no possibility of evidence of the past in this case).
