descartes discourse 5 in regards to machines

Descartes says that machines can be made by humans in all the likeness of humans, but a soul cannot be created for them. Only God can create a soul. So therefore, machines cannot function as a human, only mimic one. A machine can be programmed to adhere to a vast amount of functions, but still finite. where a machine fails a certain task that a human has asked of it, the human can choose an alternative approach. Humans cannot do everything, but this is not their function as intended by God. God created a human to be able to choose to change themselves. Like machines can understand their function as bestowed on them from their creator, but never understand the reason for the intention, so too can humans understand their function, but never the understand the reason of God's intent. Therefore, humans do have a will and a function, and both include choice.
