"It is change ... that is the dominant factor in society today... the world as it will be. This means that ... every man must take on a science fictional way of thinking.""
- Isaac Asimov

Brain Erasure  
  Deleting selected knowledge from the brain using electrical impulses.  

How would you respond to this advertisement?

Do you want to know more?
Do you yearn to learn? But are you repelled by the dreary months and years of study?
Electro-Education is the answer! Study, classrooms, are now obsolete!

Or, perhaps this:

WHY GO TO COLLEGE FOR KNOWLEDGE?
Would You Drive A Horse and Buggy to Work? GET SMART THE MODERN WAY!

And what if you have already loaded your brain up to its maximum capacity? You might want to erase some of that material.

"... The scanner can erase this new-found knowledge from the brain, by using a neutralizing electronic impulse. Then the student can learn entirely new subjects."
From The Knowledge Machine, by Edmond Hamilton.
Published by Thrilling Wonder Stories in 1948
