You see, but you do not observe.

You reason well, and your wit is bold, but you are too prejudiced. You do not let your eyes see nor your ears hear, and that which is outside your daily life is not of account to you. Do you not think that there are things which you cannot understand, and yet which are, that some people see things that others cannot?

आप वही हैं, जो आप तब होते हैं, जब कोई नहीं देख रहा होता है।

Perceive that which cannot be seen with the eye.

[O]ur percept is an elaborate computer model in the brain, constructed on the basis of information coming from [the environment], but transformed in the head into a form in which that information can be used. Wavelength differences in the light out there become coded as 'colour' differences in the computer model in the head. Shape and other attributes are encoded in the same kind of way, encoded into a form that is convenient to handle. The sensation of seeing is, for us, very different from the sensation of hearing, but this cannot be directly due to the physical differences between light and sound. Both light and sound are, after all, translated by the respective sense organs into the same kind of nerve impulses. It is impossible to tell, from the physical attributes of a nerve impulse, whether it is conveying information about light, about sound or about smell. The reason the sensation of seeing is so different from the sensation of hearing and the sensation of smelling is that the brain finds it convenient to use different kinds of internal model of the visual world, the world of sound and the world of smell. It is because we internally use our visual information and our sound information in different ways and for different purposes that the sensations of seeing and hearing are so different. It is not directly because of the physical differences between light and sound.

There is nothing more real than what cannot be seen and there is nothing more certain than what cannot be heard.

Sie müssen sowohl an Dinge glauben, die Sie nicht sehen können, als auch an Dinge, die Ihrer Meinung nach bewiesenermaßen unmöglich sind.

People can't hear anything except when it's nonsense. Then they hear every word. If you try to talk sense, they think you don't mean it, or don't know anything anyway, or it's not true, or it's against religion, or it's not what they are used to reading in the newspapers...

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?

My ears hear colors and my eyes see sounds.

On ne voit bien qu'avec le cœur. L'essentiel est invisible pour les yeux.

"A few people, however, can still see and hear in the old way. But most of the members of the human race have lost the capacity to he painters, poets or musicians, and are not left the option of seeing and hearing directly even if they can afford to; they must get it secondhand. The recovery of this ability is called here "awareness.

What senses do we lack that we cannot see or hear another world all around us?

What you are you do not see, what you see is your shadow.
