Thanks for replying. I agree with what you are saying insofar as that is how science should be. I’m not so sure that’s how it is. So I think you may be being a little idealistic here.

You ask for specific examples of scientific ideologies. A fairly obvious one is the attachment to the general principle of physicalism, one example of which is that consciousness is an epiphenomenon of the brain. This has never been proved. Nor is there any scientific explanation for it, therefore no evidence, so much so that the attempt to explain it has been labelled the Hard Problem. Yet many so-called scientists remain convinced that it’s true, and certainly do not “recognize it when evidence starts to mount against their ideas”. I agree and hope that at some point “they will be pushed aside by other scientists”, along the lines of Thomas Kuhn’s new paradigm ideas. In the meantime they cling to their ideology, and show no signs of changing their minds.

So I will be happy to agree with you, if you think that physicalism, like Marxism, claims to be scientific but isn’t.

I could add other examples, but that is one of the most obvious ones.
