Today, while reading my copy of SICP and googling related stuff, I came across this guy's website where he joyfully recounted how he got his copy to be signed by the authors, after reading it cover to cover. Even it not being anything out of ordinary, it got me puzzled.
Since I'm currently working at CSAIL (MIT), it is not rare for Sussman himself or people like Rivest (RSA inventor), Stallman (FSF founder) to pass me by.
To be honest, it is indeed exciting, isn't it? But why is that?
Why do we get fulfilled through autographs, or memorabilia in general?
As matter of fact, this is so much true that people make a lot of money out of it. Look up for you favorite movie start or singer on the web to find out that he/she is probably already selling signed stuff. But wait, it is not only about famous people. We do keep our own old stuff as a way of recalling past sensations, memories...
If we want to understand this better, we should definitely take into account social interactions, after all who wouldn't love to brag about having a guitar signed by the Beatles? Still, I believe that the primary reason has to with the individual himself.
Throughout life, we find inevitable to refer to past moments or feelings in our lives or other people's. And that could happen either as a way to avoid repeating mistakes, to relive or reproduce past successes or to get closer to people we like.
Of course I'm not naive to believe this is as a complete explanation, but it suffices for now.
Thus I should finish this post exactly here.
