I'd like to know what you think of the "wrecking ball" which David Hume applies to science. Does he really show that the "necessary connections" which we commonly refer to as the "Laws of Nature" are merely based on psychological conditioning-- or, as he puts it, "constant conjunctions" of similar events? What do you think is-- or should be-- the impact of Hume and empiricism in this era of great scientific and technological advances?
