There are two issues being conflated here, I think. There may be one
logical system that somehow captures every correct deductive inference.
Logic, in this sense, might be the foundation of every science as
Steve suggests. But, that does not mean that what
the correct logical system is. Logic, as a branch of philosophy,
is to a large extent the study of correct inference to find out what
rules it uses. Hence the current debate between classical
logicians, intuitionists (such as Dummett), relevance logicians,
paraconsistent logicians, and so on.
