Hierarchy Problem: Compactification
There is an old joke which rates various branches of knowledge from more fundamental to less. The basic schema is something like math -> physics -> chemistry -> biology -> psychology -> philosophy where the punchline is that you compactify the whole schema by boundary identification, i.e. adding philosophy -> mathematics.
Lubos has a new version of the primitive schema with string theory -> QFT physics at the top and religion and mass delusions at the bottom. He forebears taking the inevitable step of boundary identification of religion and mass delusions subsuming string theory, but how can we resist?
