If you take away everything we have, we are left with our thoughts. It would certainly seem like they form the very core of who we are, or our individuality. If I don’t own my thoughts, what else could I possibly own?
And yet great efforts are made to try and control how we think. A movie can make you cry, an ad campaign can make you buy a product, a politician can earn your vote. Manipulating someone’s thoughts to make them do something is incredibly powerful.
I want to believe that what I think is somehow up to me and me alone, but I know that isn’t true. Hence the question: How much of our thoughts are our own?
