I always thought that we can imagine mathematics as a structure that was based on an unique principle and that we can see algebra, geometry, ... emerging when we're adding axioms to the first one.
In this way, all the mathematics could be represented in a large map. Someone could say how a theory and its axioms are distant from the first principle and how it relies to other theories.
Is my conception of maths wrong ? If not, what would be the founding principles ?
I would give anything to see such a diagram.
