Ämne: Re: SV: Only logic is necessary?

I'd say the decision to use classical logic is an 
assumption that you're applying it to sentences or propositions where it
will work (i.e. declarative, timeless sentences), not an assumption about
logic.  Same for geometry.  I use 
Euclidean geometry to calculate distances in my backyard, I use spherical
geometry to calculate 
air-miles to nearby airports, I use WGS84 to calculate distance between
naval vessels at sea.

Cooper says that all sentences have substans. The logic asumption is that
there are some that have not and are timless.
