Poetical assumption

"Writing starts with an assumption. There has to be space in which work can evolve - let's assume a context. There has to be a medium in which to communicate - let's assume a language. There has to be someone out there to receive it all - let's assume a reader. In Christianity, assumption stands for the bodily translation of an individual, from earth to heaven, and in a military terminology, assumption is (yet) another definition of taking control or power over a region.
