 Let us now see how this hierarchical proposal works. Consider an abstract pattern of curving lines, which is elegant. It might be necessary that that pattern is beautiful. This is because the beauty depends on or is determined by that specific pattern. But it is not part of what it is to be that pattern that it is beautiful. That is, the pattern is necessarily beautiful but it is not essentially beautiful. (On the general distinction between necessity and essence, see Fine 1994.) Furthermore, we can think of that pattern without thinking of it as beautiful.
