Thanks be to blessed Nature because she has made what is necessary easy to supply, and what is not easy, unnecessary. (Ioannes Stobaeus Anthology, XVII.23)
We cannot say that the good which has rounded out a happy life, the good for which Epicurus rendered thanks in the last words he uttered, is not equal to the greatest. (Seneca, Letters to Lucilius, 66.47)
But what epithet do they deserve – with your "roars" of ecstasy and "cries of thanksgiving" and tumultuous "bursts of applause" and "reverential demonstrations," and the whole apparatus of adoration that you all resort to in supplicating and hymning the man who summons you to sustained and frequent pleasures? (Plutarch, Against Colotes, 1117A)
[Epicurus] writes this to his friends about himself: "The way in which you have provided for me in the matter of sending the grain was godlike and magnificent, and you have given tokens of your regard form me that reach to high heaven." So if someone had taken that corn ration of his bread-stuff from our philosopher’s letter, the expressions of gratitude would have conveyed the impression that it was written in thanksgiving for the freedom or deliverance of the whole Greek nation or of the Athenian state. (Plutarch, Contra Epicuri Beatitudinem, 1097C)
