Bradski has it correct; emotions are a movement of appetite, of which desire, love, hate, sorrow, anger, etc., are several of the movements, tending toward establishing union with what is perceived as good to be united to, or tending to avoiding what is apprehended as bad to be united to.
Cognition is in reference to thinking about what your senses apprehend, in order to understand what you are experiencing.
Cognition, or reasoning about what you are experiencing can end up with a “judgement” that “this is BAD news to be near this thing I am approaching”, upon which the appetite automatically moves a movement of fear, an escape tendency (or perhaps a fight tendency).
But this movement can be moderated or reversed by the Will and intellect, as a voluntary movement of the Will, which can temper the appetite with its passions (emotions).
