Remember too that when people get to make their own purposes, the door is opened to limitless variety, with no individual purpose better than any other. There would be no way to say, for example, that Megan the social worker could have a purpose that was any better than Robert the stockbroker or even (as ghastly as it sounds) Drake, the sex-slave trader, since that would require a Purpose that served as a kind of benchmark the others could be measured by. But in matter-ism that benchmark does not exist.
