Nye is a good example of someone who promotes science as a close-minded ideology, not an open search for truth.
A real “March for Science” would celebrate scientific puzzles, disagreements, and competing ideas rather than fear them.
Just ask Italian philosopher of science Marcello Pera. In his book The Discourses of Science, he writes that science advances as scientists argue about how to interpret the evidence. They can only do that, though, if they are free to challenge established ideas and advance new ones.
Those who truly want to support science should defend the right of all scientists — including dissenters — to express their views. Those who stigmatize dissent do not protect science from its enemies. Instead, they subvert the process of scientific discovery they claim to revere.
Ron Bailey at Reason reminds us of an important point:
One problem is that many of the marchers apparently believe that scientific evidence necessarily implies the adoption of certain policies. This ignores the always salient issue of trade-offs. For example, acknowledging that man-made global warming could become a significant problem does not mean that the only “scientific” policy response must be the immediate deployment of the current versions of solar and wind power.
