I wanted to quickly drop in to this thread to say that this episode has brought up some questions for me - regaring the use of the word "pleasure" in every-day speech.
I personally feel that I want to start using more words, and different words, which are more accurate for each and every given situation.
The word pleasure can encompass so much, however in my mind and perhaps others who speak English, the word pleasure is used to apply to sensations that have a certain intensity and stimulate the senses. (Perhaps other languages/nationalities have a different understanding than American/British people. For example, in France they might say "It's a pleasure to meet you" - but in the USA we would never say that.)
So then more accurately we would say that the goal of Epicureans is to seek out pleasing experiences, pleasantness, and also pleasures (sensations) - what is agreeable, pleasant, and pleasurable. When is comes to mental pleasure we say "enjoyable" or "pleasant".
