Graduate Copenhagen: Restriction on knowledge or restriction on ontology?

Click For Summary
The discussion centers on the Copenhagen interpretation of quantum mechanics, debating whether it restricts knowledge or ontology. Participants argue that the interpretation suggests certain properties, like position and momentum, do not exist outside of measurement, challenging classical views of reality. The implications of the Bell theorem are explored, indicating that if something exists, it must adhere to non-local laws, contradicting local interpretations of nature. Some contributors emphasize that quantum systems lack classical properties until decoherence occurs, suggesting a need for a new understanding of quantum reality. Ultimately, the conversation reflects a tension between traditional physical realism and the non-representational views of quantum mechanics.

It is an illusion however that we could have done otherwise.
Yes, but the illusion is so strong that nobody really thinks that way when one is doing something.

No reality until observed.
I think it would be more accurate to say no values for observables until observation. That is not the same as denying reality.

Perhaps plural values is more accurate. There are values, they just aren't fixed.
