  On top of that, the intermediate effect, or non-basic value, (e.g. experiencing pleasure) can have a diminishing contribution to value. Varying diminishing marginal value in these cases is easily explained psychologically. It is just the way we are—we get less and less enjoyment from donuts as we eat more and more (at least in one sitting). However, we may well get the same amount of enjoyment from the tenth Johnny Cash song that we did from the first. In order to deal with the higher and lower pleasures case the monist will have to argue that pleasures themselves can have diminishing marginal utility—the monist can argue that gustatory pleasure gets boring after a while, and hence contributes less and less to the super value—well being, or whatever it  is.[9]
