The Eye Sees Only What The Mind Is Prepared To Comprehend.

Not what the mind sees, but what the mind imagines the eye must see.

People only see what they are prepared to see.

"We're eye doctors."

"What's something about the eye that most people don't realize?"

"The eye doesn't see. The brain sees. The eye just transmits. So what we see isn't only determined by what comes through the eyes. What we see is affected by our memories, our feelings, and by what we've seen before."

We all see only that which we are trained to see.

The mind knows only what lies near the heart.

A person hears only what they understand.

The eye of the human understanding is not a naked organ of perception (lumen siccum), but an eye imbued with moisture by Will and Passion. Man always believes what he determines to believe.

...be wary of evidence given by others, for in all evidence there is some interpretation. The eyes see, the mind explains. But does the mind explain correctly? The mind only has what experience and education have given it, and perhaps that is not enough. Because one has seen does not mean one knows.

It is only with the heart that one can see clearly, for the most essential things are invisible to the eye.

Here is my secret. It's quite simple:
One sees clearly only with the heart.
Anything essential is invisible to the eyes.

It is only with the heart that one can see rightly; what is essential is invisible to the eye.

Man sieht nur mit dem Herzen gut, das wesentliche ist für die Augen unsichtbar.

Hence at any moment only part of the visual elements of a scene is available for conscious perception.
