I have been thinking a lot about Descartes viewing animals as machines and the more I think about it the more implausible it seems. If animals are seen as machine, then what are we? I feel that people act much more like machines than any animal does. We are very much driven by time and routine. We leave the house at the same time everyday to get to class or work. We do things step by step in our everyday life. Shampoo goes before conditioner, etc. I started working at a restaurant and that is also very formulaic. Once you ask the customer the same set of questions, walk them to the table, put the menus down, and go grab them water and tell them "a server will be right with you". Animals on the other hand are on no set schedule. They don't check the time every few minutes to make sure their day is on track and they are not going to be late for the next place they have to be, they just do.
