Whatever logical statement is made, it is only as strong and truthful as its premises. A premise may be 2+2; the conclusion is = 4. Two pulse two is a strong premise as long as 2 always means 1+1. But if 2 ever changes to mean one;then , the conclusion of 2+2 is two instead of 4. But remember the premise changed. In reality the less a premise has changed, the more dependable is the logic.Sorry, can you explain that. I'm not sure what you mean about premises and conclusions about what is real.
God is the most basic premise to everything man knows, not experience,not humanism,not communism but God. If one does not believe in God, he has rejected all premises upon which to make conclusions. Is that what you were looking for?
