@Setanta,
Quote:If there are "simple facts," then upon what basis do you allege that we may know what they are?
Upon the basis of naturalistic science. Facts are uncovered, but theories are created.
Take E=MC2 for instance. The equation is sound enough, but if we want to use it to form a theory, it is likely that we will carry our assumptions about energy, mass and movements with us. The result will be something we can relate to, but even though every single fact that supports the theory checks out, that is no guarantee that the theory itself is valid.
Ptolemy devised a system that can be used to navigate the oceans with pretty good accuracy. The system he devised is fundamentally flawed, since he believed the earth to be the center of the universe. The usefulness of his system indicates that it is a correct description of the movements of stars and planets, though we know today that it is not.
Similarly, usefulness is often the criteria by which we judge the success of our efforts. But we know from history that it is no guarantee that we don't have most things wrong...
