By creating a self-policing, self-reporting, sort of self-monitoring culture through law, through statute, and imposing that on the academic world, I think not only are we losing a significant measure of freedom in academic traditions and in our civil society, but we're actually making ourselves less competitive with every other country around the world that does not do that. Because that's where researchers are going to go and that's where academics are going to go. And ultimately, that's where breakthroughs are going to occur.

I have been to the darkest corners of government, and what they fear is light.
