Roy Sorensen interviewed by Richard Marshall @ 3 AM Magazine: his views on armchair philosophy and experimentation have my eyebrows raised. Color me skeptical, especially after a peculiar example or two of his. From the article: Suppose I cut the handle off your coffee mug leaving two holes. Would the coffee flow out of one hole faster than the other? If we tried to figure this out by experiment, we would need to carefully measure the flow – and we would ruin your mug. We should instead mentally replace the handle with a tube. If the flow of one hole exceeded the other, we would have a perpetual motion machine. Since that is absurd, we can deduce that the holes have the same rate of flow.
