Atkins continues to this day to argue based on scientism. For a professor, he isn't much of a student.
If one adopts scientism as the only way of knowing, then you can't prove even scientific theories are true since they are based on:
- Mathematical truths not provable by science
- Logic truths not provable by science
- Philosophy of science truths not provable by science
- The majority of which are tested empirically in an external world I can't prove exists using science.
- Experiments are performed by scientists that also can't be proven to exist using science.
- Further Science progresses over time which requires the past to be a real feature of this world which in turn is not provable using science.
- Scientist test intuition and inference, not provable by science.
The majority of the world we engage every day is done so without scientific knowledge. Now that doesn't mean science isn't a valuable method for understanding a portion of the physical world.
When a person makes a claim at knowledge or to oppose such a claim watch to see if they are a arguing based on scientistic assumptions, incoherent ones.
Example:
2+2=4 is not a scientific statement, it is a mathematical one.
It is proven with math and logic.
If one were to boldly claim "No one is able to prove to me 2+2 =4 using empirical methods (AKA Science)!" They are betraying their scientism because we are applying an epistemological method (method for gaining knowledge in a specific field), that isn't able to tell us about immaterial, non-physical, abstract objects.
Equally I couldn't prove that the law in the U.S. is that all vehicles must drive on the right side of the road using science. This is proven using Law.
These are just tricks. And not very subtle either. One post should be enough to dissuade the average reader. At the undergrad level it takes one conversation, at the grad school level I hardly run into this trick, but at CF it is popular and many atheists defend it tooth and nail.
Finally, while we can easily reject the fallacious claims made by Peter Atkins in this video, this leaves us without positive claims for why one should believe God exists. For that video search for the full-length debate.
