"The limit in the amount of pleasures
is the Removal of all pain.
Whenever there is Pleasure,
then for that time that it is present,
there is no Pain or Sadness
or any Mixture of both."
Metródoros makes the same point from a different angle:
"Τhis very thing is the good:
Escaping from the bad-
because It is not possible for the Good to be placed anywhere
when neither What is painful nor What is distressing is any longer making way for it."
Τοῦτο αὐτὸ τὸ ἀγαθόν ἐστι:
τὸ φυγεῖν τὸ κακόν-
ἔνθα γὰρ τεθήσεται Tἀγαθόν οὐκ Ἔστιν
ὅταν μηθὲν ἔτι ὑπεξίῃ μήτε Ἀλγεινὸν μήτε Λυπηρόν"
–preserved by Plutarch at 1091 A-B in his diatribe "Ότι ουδέ ήδεως ζην έστιν κατ' Επίκουρον"
