In a real sense, the important question is never one of validity or truth. Truth exists in the realm of mathematics and in the philosophy of logic, not in perceptions of reality. For those who would understand the world about them, the question is not one of truth, but of utility. Do our investigations deepen our understanding, further our ability to ask more refined questions, and lead to better predictions of events? If so, then the research is justified. If not, it remains but sophistry.
