None of the individual metal hunks of an airplane have the property of ๏ฌight, but when they are attached together in the right way, the result takes to the air. A thin metal bar won't do you much good if you're trying to control a jaguar, but several of them in parallel have the property of containment. The concept of emergent properties means that something new can be introduced that is not inherent in any of the parts.
David EaglemanThe continuous networks of neural circuitry accomplish their functions using multiple, independently discovered strategies. The brain lends itself well to the complexity of the world, but poorly to clear-cut cartography.
David EaglemanWe open our eyes and we think we're seeing the whole world out there. But what has become clearโand really just in the last few centuriesโis that when you look at the electro-magnetic spectrum we are seeing less than 1/10 Billionth of the information that's riding on there. So we call that visible light. But everything else passing through our bodies is completely invisible to us. Even though we accept the reality that's presented to us, we're really only seeing a little window of what's happening.
