Some people find pleasure in many different ways -- do we agree on that?
We agree but it's irrelevant. The feeling of pleasure is the canonical faculty at work. We feel pleasure, then ask why that was pleasurable. Feeling, then reason. The action or thought or recollection that elicits a pleasurable feeling is then chosen or rejected to be engaged in again or not on the basis of that feeling. The feeling -- to be modern -- is a reflex response to a stimulus. Those endorphins are the same chemical reaction for all humans. We feel the pleasure before any "thinking" about why we felt it. That's why it can be a standard. It's a biological response not predicated on cognitive reasoning.
If we do, then that's the first indication that a canonical faculty gives different results for different people.
It seems to me you're conflating different "results" with different "feelings." There are different results because different people have different reactions to their feeling of pleasure. Pleasure is pleasure. Opinions about pleasure can be different. To use a metaphor: Fire can be used to burn a house down or cook your food. The results are different, but the nature of the fire remains the same regardless of the outcome. Same for pleasure.
This is a more in depth and fascinating discussion than I can handle at 11:30 pm. I promise I'll re-engage tomorrow. For now
