Symmetresis" is the word I prefer to use in the place of "hedonic calculus."
That post cries out for explanation, Nate!
ΣYMMETPHΣIΣ – συμμέτρησις – symmétrēsis – Epicurus uses the word as συμμετρήσει (symmetrēsei) when describing “measuring things side by side and looking at both the advantages and disadvantages” (Ep. Men.)
In Epicurus’ Epistle To Herodotus, he uses several inflections of the word to refer to the process of arriving at correct judgments about sensation: σύμμετρον (47, 50), σύμμετροι (54), συμμετρότερον; and then several more times in his Epistle To Pythocles: (91), συμμετρίας (107), συμμέτρως (110), συμμέτρως (111), συμμετρήσει (130).
