James J. Gibson

“The affordances of the environment are what it offers the animal, what it provides or furnishes, either for good or ill.”

“The meaning or value of a thing consists of what it affords.”

“We must perceive in order to move, but we must also move in order to perceive.”

“Information is not just in the head. It's in the world.”

“To see the world is to see what it affords.”

“Behavior is a function of the person and the environment.”

“Ask not what's inside your head, but what your head's inside of.”

“Perception is not a matter of having sensations and then interpreting them. It is a matter of directly picking up information from the environment.”

“The richest and most elaborate aspects of visual perception have to do with the layout of surfaces.”

“The senses are not channels of communication but organs for exploring the world.”
