“Education is the most powerful weapon which you can use to change the world.” That according to Nelson Mandela.
I object to the characterization of education as a weapon. Weapons are used as tools of destruction, not construction. Remember the distinction between tools and weapons: all weapons are tools (instruments; means to an end) but not all tools are weapons (“any device used in order to inflict damage or harm to living beings, structures, or systems.”)
Changing the world is a fine objective. Most people want some changes in the world around them and most people (though not all) want some change in themselves too.
