P. 189 of Green when discussing the properties of the language faculty -
talks about interfaces - this I take to mean "connection between any 2
functioning units, including organisms" (Penguin dictionary of
Psychology) Is this just saying that our language component of our
mind is divided up into 2 further subsections - Logical form (LF) and
Phonetic form (PF) each performing a different function?

>From Harnad's notes I understand that LF is when both the
person saying and receiving needs to understand the meaning
- its cold in here - meaning can you shut the window.
And is PF the section that sends signals to our motor
systems telling them that we need to talk? I.E. the tongue,
jaw, lips, etc.

The next question: is LF the same as Pragmatics? Asking
someone to do something in a round about way.
