Scientific Veil of Ignorance

I've spent the last couple of days hashing out an idea I've had. I use Rawls' original position as a model for a new original position, the scientific original position. A group of scientists must choose a scientific methodology faced with a very real veil of ignorance. They do not know what theories are actually true in the world they inhabit. I've gotten pretty far in a short while, and have chosen to post the introduction. I am strongly considering using this as my writing sample for my graduate applications. I need to flesh it out a little more, though, and clean up the writing.
