I'd call that realistic rather than pessimistic, and I'd call it much preferable to imagining that there is a better life after death, or a magic pill that overrides nature, becaus those things just don't exist, and I'd rather know the truth about my situation rather than spend whatever time I have under fake pretenses.
I agree, well said.
"A man cannot become wise with every kind of physical constitution, nor in every nation."
This one has always been a bit prickly for me. If Epicureanism is a philosophy that is beneficial for everyone, and wisdom is so vital for prudently pursuing pleasure, then the idea that certain people are involuntarily unable to work towards this feels rather deflating. What is one to do if they lack the “physical constitution” or live in the “wrong nation”? Does Epicureanism still have something to offer such people, or are they better off looking elsewhere for pleasure and the reduction of pain?
