In fact, the brain generates its own reality,
This idea of reality is going into idealism.
-
seemed completely real. They didn’t just imagine pictures, they saw.
Materialist versus Idealist versus Realism
-
It feels as though you have direct access to the world through your senses.
Quantum mechanics thooo. Does having direct access to something make it real.

Is the quantum wave function real? What does it mean to say that it’s real?
Yes. Particles behave as waves until observed in a manner that directly causes it to collapse.
-
Which view of quantum reality is most plausible? The Bohmian view? The Everett view?
Ngl les be fun. Everett view!
-
How does quantum mechanics bear on the age-old philosophical debate between materialism and idealism? Does it tip the scale in either direction?
Quantum mechanics tip the debate to idealism, especially with concepts such as uncertainty and consciousness affecting reality. Quantum mechanics has a place for idealism.
-
if you measure it twice, within a short span of time, you will find that it has the same value.
Because the first measurement collapsed the wavefunction, so subsequent measurements will come to the same result in the case of a particle's eigenstate.

“many worlds,”
Moooltiversee
-
the world of our perception is just a projection of an incredibly high dimensional configuration space.
Like video game code, and what we see is the projection of the code
-
Everett interpretation of quantum mechanics.
Many-Worlds theory. Multiverse!
-
realist interpretation of quantum mechanics
That what is real is independent of us.
-
Bohmian mechanics also postulates the existence of a hidden field that guides the particle configurations
Pilot-wave theory. There is a wave that guides particles.
-
subjective idealism
Mind-only approach to reality. Reality is real only when we think about it.
-
But why treat particle configurations as special? One reason for thinking that particle configurations are always determinate is our eyes seem to tell us that this is the case!
Why is knowing the specific position of particles so important to us? Because our eyes, what we see, is what is perceived as "real."
-
Why would an electron have a state of motion, but not have a position?
But only for that moment that is measured. Have they measured the same electron for another metric?
-
So how are we to reconcile the fact that sometimes the electron doesn’t have a position with the fact that, whenever we look, it does have a position?
It's like our brain uses something beyond frequency but the idea like a radio. It can tune into what it seeks to find.
-
Whenever a conscious observer tries to determine the position of the electron, she will always finds that it does indeed have a position.
Because we are tuned into that measurement.
-
We’re saying that if the electron has some position, then it does not have any state of motion.
So for every discrete moment, an electron is limited to what type of measurement it can be. A snapchat. But the next moment can it be a different type, right?
-
There doesn’t seem to be any direct analogy between quantum reality and the reality we perceive with our senses.
How about what's in between a person blind from birth and a person who was blind but now they see. The latter, although can no longer perceive sight, has knowledge of what is sight. Whereas the former has never had perception of sight. How you do explain to one who is blind how it is to see. By attempting to use sound, right--by taking, that is? So same in quantum mechanics. How do we know what we don't see? Well, let's see if another signal can give us insight.
-
And we already knew that we are made of things that are too small for our eyes to see.
We can't see things too small or not within the visible light spectrum for humans.
