- Cogito Ergo Sum - I think therefore I am
It's possible that they don't exist, but I think that would ultimately create more philosophical problems then it would solve.
So mostly, FUCK YOU Descartes for attempting to prove to me that some people don't exist.
- Analytic Geometry - The Cartesian Coordinate System
For a platypus I am a well educated individual. If one can assume a B.S. in Anthropology is actually well educated, and I think there is some reason both for doubt and not doubting that is the case. But this is one thing I can never forgive Rene Descartes for. His coordinate system makes about as much sense as chimpanzee feces splatter on a picture of Lady Diana.
- Cartesian Doubt
This is the idea that we should through everything under the light of skepticism, even if it is absolutely absurd to do so. In other words, Rene Descartes was bored one day contemplating his bellybutton lint (his abnormally shaped bellybutton gathered lots of lint) and he decided that he was going to have a thought experiment.
I am usually a big fan of thought experiments they work well in cooking, theoretical physics, and writing.
Thought experiment: If Rene Descartes was being dangled over a pit of firey burning lava and you had the choice to save him and in doing so you would save half the worlds population from starving to death for a day OR if you don't save him you will bring world peace and an end to world hunger. What would you do?
I think I had a better point at some point.
