What place does "simple" have in Epicureanism?

I will throw this in:

"For the one who is accomplished, this is the most important thing produced by total accuracy: to be able to quickly use one's attention with each thing referenced by simple component principles and statements"
-- Epikouros D.L. 10.36b

The "the one who is accomplished," that is, a student who has gone through all the material is a fun word: ὁ τετελεσιουργημένος,"te-te-le-si-our-gē-me-nos" (or tetelesiourgēmenē for a woman).

Good point as to the context of the statement in the letter to Herodotus. The word "simple" has a huge number of connotations and it would be good (as stated in the first post) to flesh out which ones are and are not relevant to Epicurus. I think a lot of people tend to associate the word first and foremost with something rhyming with ascetic, but that's not at all the only option. Dictionary.com

He's the section from my recent talk:

Did the Epicureans follow a simple, plain, frugal lifestyle? Yes, from all descriptions they appeared to live a simple, plain, frugal lifestyle… NOT unlike other average ancient Greeks of the time. Not “spartan,” not “ascetic,” not a life of self-denial! Simple, plain, frugal. Frugal doesn’t mean self-denial.

Words and phrases along these lines often associated with the school were:

Simplici victu = They led a simple, plain way of life

οἱ τε λιτοὶ χυλοὶ = They had simple, inexpensive, frugal flavors and tastes

Καλιάδα = a simple cottage (Philodemus’ description of his apartments in the lavish estate of Piso)

εὐτελέστατα καὶ λιτότατα διαιτώμενοι = lead one's life in a manner that was easily paid for and simple, inexpensive, and frugal.

To me, this doesn’t sound like self-denial or asceticism. It sounds like common sense! It sounds like Epicurus is reminding people to live within their means!

Having just finished Dewitt’s “Epicurus and His Philosophy”, the following idea is fresh on my mind:

“Moreover, it was Epicurus who specifically declared that a laborious life was inconsistent with the perfect bliss of the gods…” - dewitt, pg.53

And:

“This notion was so well known as to have been familiar to the dull Horatian commentator Porphyry, who lived early in the third century A.D. Horace had quoted freely from Lucretius: ‘I have learned the lesson that the gods live a life free from concern.’ 60 The comment runs: ‘This derives from the doctrine of the Epicureans, who assert that the gods cannot be immortal unless enjoying leisure and immune from all responsibility.’"

To me, this is the spirit of “the simple life”; avoidance of that which one finds excessively laborious. The simple life is one in which prudent planning ensures your needs are met, your health of mind and body is maintained, and pleasures abound, all with only exactly as much effort as is required and no more.

To me, it’s the opposite of the “rat race” of modern society. The gluttonous levels of consumerism, the social posturing with large houses, exepensive vehicles, and wildly expensive lifestyles that require constant upkeep and 80 hour work weeks.

“Simplicity” is a call to figuring out what truly pleases you, avoiding the all too common “hamster wheel” of life, and realizing that most of the greatest pleasures of being a human on earth don’t require much effort to obtain.

Quote from Al-Hakiim von Grof

Al-Hakiim von Grof RE: "a laborious life was inconsistent with the perfect bliss of the gods"

Thanks for that clarification to avoid "excessively laborious" actions. Certainly, we should labor to meet the simple daily needs for ourselves and our family. We can find pleasure in laborious tasks that build something beautiful that gives ongoing pleasure to us or to friends and families, or local community. I fully agree with your definition of "the simple life". For me that definition of "the simple life", is one where these "simple" actions or avoidance of actions leads to a balanced/stable & fulfilling life (eustatheia & eudaimonia).
