text: The rationale, according to one kind of duality (S-duality), is that one theory at strong coupling (high energy description) is physically equivalent (in terms of physical symmetries, correlation functions and all observable content) to another theory at weak coupling (where a lower energy means a more tractable description), and that if all the theories are related to one another by dualities such as this, then they must all be aspects of some more fundamental theory.
