I recently listened to a song from the album A Thousand Suns called Wretches and Kings (good song, 3 uses of the s-word if you want to listen), and a part kept coming up. Something about machines and putting bodies on the levers and you got to make it stop? I didn't know what it was so after looking up some of the phrases I remember, I found the speech "Bodies Upon the Gears/ Operation of the Machine" by Mario Savio on December 3, 1964. Here's the part that was highlighted: 

"There is a time when the operation of the machine becomes so odious, makes you so sick at heart, that you can't take part; you can't even passively take part, and you've got to put your bodies upon the gears and upon the wheels, upon the levers, upon all the apparatus, and you've got to make it stop. And you've got to indicate to the people who run it, to the people who own it, that unless you're free, the machine will be prevented from working at all!"

     The song was about people being manipulated by groups and higher-ranking people claiming power and how the manipulated and deceived need to rise up. So how does a speech like this fit in a song about social control? Well, the machine can be seen as the groups/people taking and the bodies put upon the gears, wheels, levers, and the apparatus are the deceived and manipulated. Mario calls for the people whose bodies are upon the machine to rise up and rebel against the manipulators and deceivers. The quote has been taken out of context, but it was for a sit-in against the University of California Berkeley. This part gets referenced the most and is a true encapsulation of what the Free Speech Movement was. If anyone has another example of this in the media, please let me know as Linkin Park is the only one I know of so far. I hope you research this movement and learn how impactful this speech was to the movement it represents. Here's one for you to get started with: Free Speech Movement | UC Berkeley Library
