Titus -- In further response to your question, the need to focus on a few core ideas is why I added the graphic that appears at the top of the right sidebar on the home page now. I am sure the list could be tweaked and wording improved, but at the moment these four are my best effort at selecting the most important distinguishing issues about which there ought to be unity. In my view the "tetrapharmakon does not cut it for this purpose, because (1) the focus on pleasure as the goal needs to be more clear and explicit, and (2) the separate of Epicurus from "virtue-based" reasoning is probably so important as to be in the main list. The "all good and evil consists in sensation" doesn't include the word virtue but it does provide a direct quote which seems a good starting point (as with the 'blessed life" quote). I would be tempted to substitute Diogenes of Oinoanda's "shout" quote, to clearly set out that virtue is a means to pleasure and not the end in itself, but that's probably too long for a pithy summary. However if there were one I would be tempted to change if the space allowed it, it would probably be to try to incorporate a short version of the "shout" quote or something from Torquatus on virtue. As it is, I would just use the Diogenes "shout" or explanation from Torquatus in explaining what the "good and evil" statement means.
So this is my best effort currently.
