Donald Hoffman: Do we see reality as it is?  (script)
Summary
What is seeing? It seems to be said from in the past that a state of consciousness comes about the results of irritating nervous tissue. It's the relationship between your brain and your conscious experiences. It's not still clarified, because we ourselves seem to think that we lack the necessary concepts and intelligence to solve it and we are unable to solve also.
However, the speaker has different thought: those might be wrong and our vision is not like a camera. It's because you would have experienced that you misinterpreted your perceptions before.
In our brain, billions of neurons and trillions of synapses are engaged in vision. Their works are creating all the shapes, objects, colors, and motions that we see in real time. It's not taking a snapshot as it is. They're constructing everything that we see. They don't construct the whole world at once. They construct what we need at the moment. That can be explained by the three-dimensional cube can be translated to the screen of flat, in our brain. We have experienced that.
And then, perception evolved to survive. So the organisms which can see all of the reality are going to extinct. Thus, perception is constructed, further reconstructed to adapt environment. It'll be difficult to think that we're blind, however, we have to recognize that perception is not about seeing the truth.
