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 Cognitive Style of PowerPoint An Essay by Edward Tufte www.edwardtufte.com In corporate and government bureaucracies, the standard method for making a presentation is to talk about a list of points organized onto slides projected up on the wall.

Early in the 21st century, several hundred million copies of Microsoft PowerPoint were turning out trillions of slides each year. Alas, slideware often reduces the analytical quality of presentations.

And how can we improve our presentations? Ban PowerPointsA Conference Without SlidesDocuments vs. decks
