Babies are a more common miracle than suddenly cured blind men, and it turns out you can ask them Locke's question, too. They think Locke, like Berkeley, got it wrong. Andy gave one-month-old babies one of two pacifiers to suck on. either a bumpy one or a smooth one. The babies necer saw the pacifiers. They just felt them. Then he let the babies look ar bumpy and smooth objects, without letting them feel them. The babies looked longer at the object that was the same shape as the one they just been sucking on. Somehow, they could relate the feel of the pacifier in their mouths with its visual image.
