J.L.Marroquin (1976) in “Human Visual Perception of Structure”

There is…a basic issue that is only very seldom discussed: What do we mean by “visual experience”? Very often the problem of vision is oversimplified, and to “see” a scene is identified with the task of computing a verbal description of it. This problem is difficult enough, but it is important to recognise that there is much more in visual perception than assigning verbal labels to “objects”.
