A lighter note

So when I was in my intro to logic class this semester my professor at one point was talking about Descartes and his skepticism and I described it to a friend of mine with an example that was something along the lines of "Imagine you have a favorite pen. One that you know everything about, all the sights smells feel etc. and one day you let me bring it home as a favor and I bring it back to you the next day just totally burnt up. Its no longer the same color, shape, size, feel, any of that. How do you know its the same pen you gave me?" thinking I was being a real smartie with the thought experiment.

Fast forward a month or two and I'm reading Descartes's meditations and come across the exact same thought experiment, only using a block of wax instead of a pen. My "original idea" turned out to be something like 500 years old.

So I got a real kick out of the irony of that but at the very least I'm thinking like a philosopher!
