So, it would seem as if pleasure exists as a function of pain. This is because we know, at one end, no pleasure = 100% pain, and at the other, when we "fill the tank", we have a 100% effective pleasure, and a complete elimination of pain.
It is worth to clarify whether or not this is the point where the natural and necessary desires are fulfilled and we get into the territory of the other desires. Or is there no association/correlation?
So, since pleasure is clearly a function of relieved pain, it's consistent to think that the pleasures obtained after the threshold (of the elimination of evident pain), are also eliminating some pain too, albeit a non-evident one.
From the beginning of this post, Maslow's hierarchy started looming. At this point it seems more relevant, but I won't digress there.
The thing is that, it would seem, the "tank" is not the only place that takes "gas", apparently. There are other places in the "vehicle", less evident than the tank, where there's a capacity to receive gas, while not a necessity for it. A "reserve", would be a good analogy, as this is not needed, but can get you out of trouble. So, having access to fun stuff to do, can help you cope with hunger.
Does this make sense?
This makes sense to me, as this framework seems consistent and helps me to assimilate the PD.
Is anything contrary to any other PD or teaching?
Also... of the pleasures we can find beyond the threshold (of evident pain relieving), it could be smart to learn what pains are they eliminating, for us to gain more control and understanding over our experience. Going psychological here, if there's a pleasure I constantly seek and indulge in (which is, as accepted before, eliminating some pain) but that overall ends up producing me more pain afterwards (think addiction), it would make sense go try and find what is that non evident pain (most likely mental distress) that I'm eliminating with the pleasure, thus becoming capable of eliminating the vicious cycle in a reasonable manner consistent with the philosophy, rather than brute-forcing yourself out of it without addressing the root cause. What do you think?
