Full Idea

Even if possible worlds could differ in many different respects, there is no useful way to combine these different respects into one measure of overall comparative similarity.

Gist of Idea

Worlds may differ in various respects, but no overall similarity of worlds is implied

A Reaction

[idea of Michael Moreau 2010] This is an objection to the use of 'close' possible worlds in causation theories. The idea is true in general of the concept of similarity. It makes sense of specific 'respects', but not really of two whole objects.
