The eye sees only what the mind is prepared to comprehend.

Reality is merely an illusion, albeit a very persistent one.

Perception is not reality, but, honestly, it's what matters. It's everything.

The map is not the territory, but we navigate by these imperfect maps we've drawn in our minds.

What we perceive is not nature itself, but nature exposed to our method of questioning.

The mind is its own place, and in itself can make a heaven of hell, a hell of heaven.

What you see and hear depends a good deal on where you are standing; it also depends on what sort of person you are.

Perception is the first act of creation - before we can change the world, we must first perceive it differently.

The world appears different when you stop telling yourself stories about what you're seeing.

Our perceptions are hypotheses about the world, constantly being tested and updated.

To see is to forget the name of the thing one sees.

Perception creates our reality long before reality confirms our perceptions.

The most difficult subjects can be explained to the most slow-witted man if he has not formed any idea of them already; but the simplest thing cannot be made clear to the most intelligent man if he is firmly persuaded that he knows already.

We don't see the world - we see the story we tell ourselves about the world.
