Argumentation theorists can make a much larger case for the significance of their discipline than they appear to do. This larger case entails asking the overarching question, "How is knowledge driven?" and seeking the answer in arguments for which there is near universal agreement that they drove the growth of knowledge. Three such benchmark arguments are Newton's on motion, Darwin's on evolution, and Mill's on women's intellectual equality to men. These and other seminal historical arguments suggest that alternative argumentation in (...) light of evidence is the mechanism which drives the gro';1h of knowledge. There are also a number of surprising results, among them that even the most epistemically salient arguments contain significant errors and that what is "reasonable" is a constantly changing intuition which is biased against superior but nove! ideas. This approach suggests a new fallacy as well, the intuitive fallacy of believing that plausibility is evidence for likelihood. (shrink)
