Looking at art should be like walking in the countryside．You may not know exactly where you are，what bird is making that strange sound， or what the hill ahead of you is called，but that's part of the fun of it．You don't need to know these things to feel the beauty of nature．

    Of course， if you do know your birds， trees and local history， a walk can be more attractive． Yet such knowledge comes slowly． It is picked up through experience．A true knowledge of nature cannot just be given to you through an app on your phone．Imagine pointing your phone at the hill and getting plenty of information on screen． Would that enrich your dreamy walk or ruin（毁灭） it？

    Braggarts enjoy an app that allows them to show off their knowledge， for example， about baroque（巴洛克风格的） paintings． In fact， apps in museums try to provide on﹣screen art history at once just to encourage people to read their phones instead of looking at paintings．

    It is a mistaken idea that you need to be spoon﹣fed（灌输） amazing facts about a work of art in order to appreciate（欣赏） it． Our first experience of a work of art should be raw（自然状态的），unguided，and a bit puzzling， like following a path in the woods． Later， you might choose to do some personal research into the work． It can further increase your enjoyment and appreciation for it． Yet it is best done when you're away from the art itself， so that even when you return， the work still feels fresh．

    Anyone who thinks knowing some dates and details makes you better understand a work of art is wrong． We all need to put aside our screens and our supposed knowledge when we look at art． Let the paintings flow in； let your intuitions（直觉） fly off． Art is a journey in the wilderness or it is nothing at all．
