Erasers are one of the best things man created for his feasibility. They let you rub out the bluntest of mistakes, and the darkest of errors; giving that fake impression of a clean, blank sheet by actually putting ‘originality’ (if such a thing exists) at stake.
Can a word re-written have the same effect as the Written Word?
The problem is, that even after erasing a blot of black from your sheet of white, you don’t necessarily forget what was there before. By blurring that image over there, you kinda make it more prominent on your mind’s slate.
They are awfully good at keeping such memories, by the way.
My point is: Humans make mistakes. Mistakes make humans human. But erasers keep you from acting responsibly, at times, by telling you that it’s OK to do that again for even a hundred times if you may — blinding you from the fact that this would eventually tear an otherwise precious paper off— in the most brutal of ways.
