I’ll respond to all these fantastic responses more in depth tomorrow, but for now I just wanted to mention how much I appreciate that Epicurean philosophy is grounded in everyday reality.
Regardless of all the abstract reasoning I’m engaging in while trying to understand this point, the final judge is the senses and what I’m actually experiencing. I know and I can see clearly that a life of nothing but bread and water would leave me unsatisfied, despite my hunger and thirst being satiated. It is obvious to me that the pleasure of trimming my fingernails is not equivalent to the pleasure of dancing with friends.
So despite my confusion here, I don’t doubt for a second the validity of the philosophy. I can be sure of this because the conclusions align with what I actually experience - the proof is in the pudding.
Even while figuring out how the clock works, I can be sure that the time it displays is accurate.
