"Remember that for Ockham there is nothing in the universe that is
in any way universal except a concept or word: there are no real
natures shared by many things. However, things do resemble one
another, some things more closely than others. So the various
degrees of resemblance give a foundation in reality for our conceptual
structures, such as Porphyry's tree.
Now resemblance (or similitude or likeness) is a relation.
If such relations are realities, then we can say that there are realities
out there that correspond to our conceptual structures."
