Philosophy is a dumb science where people sit on their arses watching society and thinking of ways to fix it. It has developed into an art as so many people enjoy lounging and doing nothing. People who study philosophy are called philosophers (because it comes from the main word, dumbs!).
Philosophy came from ancient Greece where Plato wrote some lame ideas on how government should work. He was known for being fat since he had no real job.
Newer philosophers such as The Thinker have done even less than old philosophers like Plato. They sit and don't even think, giving them even less value.
Philosophers are also called thinkers. Glenn Beck calls himself a thinker.
