It is a subjective and individual situation, so not something that is applied straight across the board - everyone needs to decide for themselves regarding "the absense of pain is the highest pleasure".
Thinking further on this...that on the opposite side of this idea is that this is too high of a bar to reach. If a person is looking to feel pleasure which is absent from pain, then they will be thinking with a mind-set which is looking to root out pain. This can quickly become depressing (and difficult to do). It may end up being better to think about choosing "pleasures with less pain" than "pleasures without any pain"...and choosing pleasures which crowd out the pain (and lead to health of the body and happiness of the soul).
It's important to remember that only the gods experience perfect pleasures.
Also, that means when I decide to stop buying candy, I need to choose something else pleasurable to do instead ![]()
