Question #1 – Thomas Kuhn
- Hello SGU hosts, I’m a history teacher at a high school here in Tokyo, Japan. I love your show and sometimes use it in my class. The stuff you talk about on the show and the skeptical world view you advocate is very useful for my students, as Japan is a scientifically advanced country but has a lot of problems instilling critical thinking skills in its young people. My ‘World History’ class for 9th-graders covers the Renaissance and I have a unit that traces the shift in astronomical theories from Ptolemy all the way to Newton via Copernicus, Kepler Galileo, etc. When I teach it, I always emphasize that science is cumulative and that the scientific method is the best thing humans have come up with so far to understand the universe because it is objective and self-correcting when past theories are disproven through evidence. This Christmas break I was back home in Indiana hanging out with some college friends who are now in grad school. We were having a late-night, beer-fueled philosophical discussion about science and my friends started going on and on about Thomas Kuhn and how he proved that science was a not cumulative, inherently flawed, and just one of many, equally valid human perspectives. As a skeptic, I took issue with this and a friendly, but heated debate ensued. I think it was a tie, but I would have done better had I understood Kuhn’s real argument. The version my friends were using seemed to be either flawed form the start or misinterpreted. Could the SGU hosts explain what Thomas Kuhn was trying to say in ‘Structures of Scientific Revolutions’ and also give your take on why you think postmodernists in the academic humanities (my friends and their teachers) have chosen him as their guide when they want to criticize science. Cheers, Triston McMillan St. Mary’s International School Tokyo, Japan
