Hi there!

It was requested, during the 20th chat, that I post my idea that I discussed, that pleasure and pain can be described using a Normal, or Bell curve.

Normal curves are used to describe just about anything. And are common mathematical models.

Standard deviation diagram - Normal distribution - Wikipedia

(Beware the Wikipedia article contains lots of heavy math I can't begin to fathom).

It dawned on me, that if you use pleasure inputs, for the horizontal axis, and pleasure felt, for the vertical axis, the curve would describe pleasure from and Epicurean perspective. As inputs increase, in response to pain felt, pleasure rises on the curve, finally reaching a peak at the top of the curve which is also the limit. As inputs continue to increase, the pleasure decreases as you are on the downward slope of the curve.

To give an example, say you are VERY HUNGRY! And are presented a large quantity of food. You start at the left bottom of the curve, the maximum of pain, and the minimum of pleasure, and chow down! As you are filling yourself your hunger pangs decrease, and your pleasure increases. Eventually, you peak out in pleasure at the top of the curve, but you compulsively keep eating. As you do this, the pleasure decreases, and pain increases on the declining slope of the curve until you are in as much pain as you were to begin with.

I hope you find this idea useful. Enjoy!
