I wholeheartedly agree that the tools of scientific investigation are crucial to eliminate error and objectively evaluate that which can be observed in order to counterbalance the possible distortion caused by subjective interpretation. However, to my way of thinking, the essence of science is investigation--not doubt. If science is used in the service of humanity, its mandate is to explore and expand the bounds of knowledge. The springboard is then curiosity and the goal is KNOWING. If doubt becomes the driving force of science then it often is subverted to the goal of debunking anything that cannot currently be measured or explained. Science then takes on the stature of religion and the dominant myth that is accepted is that one should not entertain, accept, or believe that which cannot be currently proven. Unfortunately, this eliminates from the arena all those things for which there are so far insufficient theory, measurements, and conceptual frameworks.
