You don't see anything, do you? You see everything but the goddamn mind; you see all the little specs and crap, but you don't see what goes on, do you?

Thou hast seen nothing yet.

Perhaps there had never been anything at all to see.

You see, but you do not observe.

we can’t see what we aren’t looking for, and don’t notice what we don’t notice.

Do not look too far for you will see nothing.

There is nothing there. What you see is not what you see. What you see is nothing. Nothing but shapes, lines, colors. What you see is whats in your mind. What you see is something somebody told you to look for. Look out for anything you see! Watch it! Watch out! Take care! Don’t leap before you look out.

You cannot see what you don’t look for, and you cannot look for what you don’t believe in.

At the moment of vision, the eyes see nothing.

It is a terrible thing to see and have no vision.

Nothing in the visual field allows you to infer that it is seen by an eye.

We can see nothing face to face; our utmost seeing is but a fumbling of blind finger-ends in an overcrowded pocket.

إذا كنت لا ترى غير ما يكشف عنه الضوء ولا تسمع غير ما يُعلنُ عنه الصوت، فأنت في الحق لا تبصر ولا تسمع.

They do not see what they look at, hence they know not what they do.
