I just read Rancourt's article. It is bizarre. But in fact, it's not that bizarre. If you know something about Dr. Rancourt's actives outside of 911 Truth, it comes as no surprise that he appears to believe there is no such thing as modern science.
Dr. Rancourt was fired from the University of Ottawa because his version of 'teaching' is shared pretty much only with himself. I will quote Wikipedia because it is handy, but the facts of his dismissal are widespread on the Internet.
Rancourt describes his approach of "academic squatting" in which he took an existing course and changed the curriculum, using student input, without the approval of the university
Now before you go citing the further Wiki statement that,
During the second class of PHY 1703, the Dean of Science, Christian Detellier, announced that it had been shut down. A single student had complained the course's content did not match the official description. Thirty students in the class who supported Rancourt's actions complained to the administration.
I'd like to point out that the course is probably so popular because of
Rancourt's assigning of A+ grades to all students in a fourth-year physics course (PHY 4385 - cross-listed with PHY 5100) in the Winter 2008 term. Rancourt gave out the grades, which were officially approved by the university, because he believes that rank-ordering students is at odds with effective pedagogy.
Honestly, is that the way you want your doctors and dentists trained?
Rancourt points out in the article that no major activist of the left supports these ideas of a 911 conspiracy. He goes on to name them - Chomsky, Ward Churchill, George Galloway, and there are more. I am sure the strongest reasons for their rejection of the idea is just its scientific silliness. But there is another issue at stake here, considering the importance that politics seems to hold in Dr. Rancourt's belief system. Being a Canadian, he may not have noticed the way that the American right has picked up 911 Truth as a banner. Now Dr. Rancourt, anarchist intellectual, shares a seat next to neo-Nazi, apologists for deniers of the Holocaust, racists who want a white Christian America, and the John Birch Society.
There are a bunch of these kinds of guys floating around 911 Truth. David Ray Griffin, A. K. Dewdney, Graeme McQueen, maybe even Steve Jones and Dick Gage - old, leftists who still think 911 is a battle against George Bush. It's not anymore. Rancourt is wrong and 911 Truth is not this dangerous, edgy, intellectual thing too sharp even for the likes of Chomsky. It's just a silly cult-like belief system that appeals to lost, uneducated, right-wing kids.
Good luck marketing your ideas as cutting edge intellectual. To me, this is all just silly right-wing politics for the confused.
