The skill of perception The newborn baby and the [blind man suddenly gifted with sight] do not have to learn to see. Sight is given to them. But they do have to learn to perceive. Perception is learnt and learnt slowly. Skill is required for perception as for speech. We are largely unaware of the skill we exercise. None of the things we have to learn to perceive are self-evident, or, apparently, instinctively evident. No doubt, however, we have an instinctive aptitude for this learning, and once we have learnt we cannot easily see as though we had not. As Ruskin says, one has to strive, if one is to see with the 'Innocent Eye'. David Pye, The Nature and Aesthetics of Design The innocence of the eyethe innocent i seeingperceptionlearninginstinct
The arbitrariness of the sign A key difference between verbal language and the modernist ideal of a visual “language” is the arbitrariness of a verbal sign, which has no natural, inherent relationship to the concept it represents. The sound of the word “horse”, for example, does not innately resemble the concept of a horse. Ferdinand de Saussure called this arbitrariness the fundamental feature of the verbal sign. The meaning of a sign is generated by its relationship to other signs in the language: the sign’s legibility lies in its difference from other signs. Ellen Lupton & J.
