these discussions also remind me of what I think is (to me) the most clear and unmistakeable way of referring to pleasure -- as "the guide" of life more so than "the good."
It's like that cliche we hear a lot today about how "the journey is more important than the destination."
Pleasure is an experience --- I'd say that the goal of an Epicurean is to experience a pleasureable life.
A non-Epicurean may be focused on the life goal of getting things and achievements, through the abstraction of "virtue" or "being (or striving to be) a good person" or "excellence" or "rising to the top". But this would not guarantee a happy life. So Epicurus says here is the path that he believes will guarantee a happy life. And also important to consider that virtue still does have a place within Epicureanism, as a tool which leads to a good experience --- to give an analogy: one properly tunes up one's car engine so that the car runs smoothly. And another anology: when playing a guitar one properly tunes the strings for the most pleasant sounds, avoiding over-tightening or under-tightening the strings -- so we "properly tune up our life" so that we don't go through life feeling tense, anxious or frought, or lethargic or sleeping all the time -- and this would be important for the experience of a pleasureable life.
 
		 
				
		
	 
															
		
 The affective circumplex and the teeter totter are both conceptual models or analogies and therefore it could be assumed that they don't fully represent the biological processes at work. They seem to imply a neutral state at 0,0 or at perfectly level, respectively. But it could be that these implied states are a failure of the analogies, or that they are so infinitesimal as to be meaningless.
