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
Induced demand Every attempt to cul-de-sac city streets, to change traffic patterns in favor of pedestrians, or to narrow street ends is met with the same howl of protest from the authorities: this will increase congestion because urban traffic is a zero-sum game. Any reduction in volume in one place in the city will inevitably be accompanied by a rise in traffic somewhere else. This claim is fallacious: the true corollary is the opposite. In case after case, a reduction of the space available for vehicular traffic has simply resulted in the reduction of traffic overall.
