Focus, for me, is a term we borrowed from photography. This means we narrow something down to a very sharp image. First, it's a notion of narrowing to something, but also, it's a notion of sharpness and clarity. Focus is one of the things that clarifies purpose. So once we get a sense of thesis, that helps illuminate the photography image, illuminate what the overall purpose of the paper is.
