Descartesí Observations on Language
Öwe must not confuse speech with the natural movements which express passions and which can be imitated by machines as well as by animals
We communicate in many ways other than language.
Laughing, crying, shouting in pain, etc.
These acts of communication are indications of our emotional state (rather than of ideas) and tend to be involuntary.
Descartes feels that these types of communication are shared with animals.
Compare the shout of pain with his description of how a machine could speak only if touched in particular spots.
A distinction can be made between language and communication.
