For the second half of the 20th century, the best philosophers of science, philosophers like Sir Karl Popper, Thomas Kuhn, Imre Lakatos and Paul Feyerabend, attempted to explain what science consists in and how it differs from myths and religion. And no matter how hard they tried, eventually, the debate died out their realization that science, much like religion, requires faith. To choose one scientific theory over another, is simply a matter of aesthetics in the hope that this theory and all to the other is going to work out.Coyne is right to criticize this, but the video is essentially correct that modern philosophers have abandoned the idea that science discovers objective truths. Popper was one of the last to believe that theories could be disproved, even if they could not be proved true, but his ideas are rejected today.
But there is no way to disprove or prove in theory. And since there is no way to prove it or disprove it, then there is no point where it becomes irrational for a scientist to stay with a failing theory.
I used to say that physicists are still believers in hard science, and had not succumbed to philosophers nonsense. But now too many physicists teach the multiverse and all sorts other ideas that have no scientific support at all.
So, the best example of this is the case of heliocentricism. Heliocentricism was first put forward about 2,000 years ago. And for about 1,600 years, it was a failing theory. However, at some point, Kepler and Galileo decided to take it up. And even though it was failing for 1,600 years, they managed to convert it in a very successful theory. The choice, however, to do so, was not because the theory was a good one — since obviously it was failing for a long time — but simply because they liked it and for some reason they had faith in it. So scientists choose to stay, we the few, simply because they have faith in it. So both science and religion seem to require faith, which means that it is not so easy to distinguish between creationism and evolutionary biology.This example is what convinced Kuhn that scientific revolutions, aka paradigm shifts, are driven by scientists who had an irrational faith (Kuhn preferred the term arational), and other scientists jumping on the bandwagon like a big fad.
As ridiculous as this is, it is the dominant view among philosophers of science today. Even physicists echo this nonsense when it suits them getting papers published.
Kepler and Galileo “converted” heliocentrism to a good explanation because of OBSERVATIONS, you moron! It was not because they had “faith” that the Sun was the locus of the solar system.That is only partially true. Kepler admitted that he could not prove that the Earth goes around the Sun.
Galileo made some excellent observations with his telescope, but his biggest argument for the motion of the Earth was with the daily tides. Galileo claimed that it caused one tide a day, which is nonsense because there are two tides a day, and they are caused by gravity, not motion.
Coyne blames religious influences for undermining views of what science is all about. I am sure that is true in many cases, but the overwhelming attacks on science in academia come from philosophers who hate religious almost as much as he does.
At least the religious folks are up-front about saying that their beliefs are based on faith.
