You´re not perceiving what's out there. You're perceiving whatever your brain tells you.

One of the most impressive features of brains - and especially human brains - is the flexibility to learn almost any kind of task that comes its way.

The brain "fills in" the missing information from the blind spot. Notice what you see in the location of the dot when it's in your blind spot. When the dot disappears, you do not perceive a hole of whiteness or blackness in its place; instead your brain invents a patch of the background pattern. Your brain, with no information from that particular spot in visual space, fills in with the patterns around it. You're not perceiving what's out there. You're perceiving whatever your brain tells you.

Death... The moment, sometime in the future, when your name is spoken for the last time.

After all, across the population there are slight differences in brain function, and sometimes these translate directly into different ways of experiencing the world. And each individual believes his way is reality.

All creation necessarily ends in this: Creators, powerless, fleeing from the things they have wrought.

As Carl Jung put it, "In each of us there is another whom we do not know." As Pink Floyd sang, "There's someone in my head, but it's not me."
