Summary Writing

An Extension of the Human Brain

Other people can help us compensate for our mental and emotional deficiencies (欠缺)，much as a wooden leg can compensate for a physical deficiency . To be exact , other people can extend our intelligence and help us understand and adjust our emotions. When another person helps us in such ways , he or she is participating in what I’ve called a “ social prosthetic (义肢的) system.” Such systems do not need to operate face-to face , and it’s clear to me that the Internet is expanding the range of my own social prosthetic system . It’s already a big bank of many minds . Even in its current state , the Internet has extended my memory and judgment .

Regarding memory : Once I look up something on the Internet , I don’t need to keep all the details for future use ------I know where to find that information again and can quickly and easily do particularly striking when I’m writing ; I ‘m no longer comfortable writing if I ‘m not connected to the Internet. It’s become natural to check facts as I write, taking a minute or two to dip into PubMed, Wikipedia , or other websites.

Regarding judgment: The Internet has made me smarter in matters small and large . For example , when I ‘m writing a textbook , it has become second nature to check a dozen definitions of a key term , which helps me dig into the core and understand its meaning . But more than that , I now regularly compare my views with those of many others . If I have a “ new idea”, I now quickly look to see whether somebody else has already thought of it , or something similar-and I then compare what I think with what others have thought . This certainly makes my own views clearer . Moreover , I can find out whether my reactions to an event are reasonable enough by reading about those of others on the Internet .
