Instead of reality being passively recorded by the brain, it is actively constructed by it.

We don't really understand most of what's happening in the cosmos. Is there any afterlife? Who knows.

Constant reminding ourselves that we not see with our eyes but with our synergetic eye-brain system working as a whole will produce constant astonishment as we notice, more and more often, how much of our perceptions emerge from our preconceptions.

It is more parsimonious to assume that the sun goes around the Earth, that atoms at the smallest scale operate in accordance with the same rules that objects at larger scales follow, and that we perceive what is really out there. All of these positions were long defended by argument from parsimony, and they were all wrong.

Humans have discovered that they cannot stop Death, but at least they can spit in his drink.

It is the most wondrous thing we have discovered in the universe, and it is us.

The deep secret of the brain is that not only the spinal cord but the entire central nervous system works this way: internally generated activity is modulated by sensory input. In this view, the difference between being awake and being asleep is merely that the data coming in from the eyes anchors the perception.
