However, it is also clearly true that a single brick -- or even a huge pile of bricks -- is not as good as a whole stable and established brick building.
That would be exactly the analogy I seek to use with the "full cup" of pleasure and what I take DeWitt's "fullness" argument to mean. Yes you want your life to be 100% pleasure and 0% pain, and you want it to stay that way, neither needlessly below the rim (due to the presence of pain) or sloshing over the rim (causing intrustio of pain due to the sloshing). But no matter what perspective you look at the vessel, what it is full of is real tangible experiential pleasure. Or using the other analogy, when you build a house of bricks you have something more desirable than a pile of bricks, but you would be a fool to then think that you have freed yourself from reliance on bricks. You don't need a greater quantity of bricks when you finish building a house in the same way that you don't need a greater quantity of pleasure when your life is 100% full of plesure.
But who would be such a pinhead or so stupid -- when you have a completed house or a full life of pleasure -- to go on a campaign apologizing for, or talking down, or even outright dismissing, the value of bricks or pleasure???
