I think Godfrey 's point that desires (επιθυμία ) and pleasure (ηδονή ) are two different things is a very important one, and conflating the two is part of the trouble in discussing this topic.
I think we had a good discussion about some of this last night.
I think most people will have no problem understanding that pleasure and pain are feelings.
But what are "desires"? I presume you are saying that they may generate feelings if met or unmet, but are not feelings themselves?
So how in plain English do we suggest Epicurus was considering desires to be described? Are they goals? Opinions? Thoughts? Will?
And how would this relate to the apparent use of the terms choices and avoidances?
