Einstein:

Except for me.

Bohr:

But it's so plausible. According to quantum mechanics, it makes no sense to ask whether light is a wave or a particle. You should ask: "Does light, or any other quantum object, BEHAVE like a wave or like a particle?" And the answer to that depends on the nature of the experiment, because it is the experiment itself that decides which aspect of a quantum object will be observed. It's simply naive to still believe that we can know anything about things independent of observation.

Einstein:

I know that as well as you do, Mr Bohr. But it is in the nature of science to describe something that is independent of how it is perceived. Despite all the success of quantum mechanics, it will never get us there. Suddenly all we are allowed to talk about are observations and measurement results anymore and not objective reality.
