Full Idea
Hume regarded the notion of resemblance as unproblematic, ..but any two objects share infinitely many Cambridge (whimsical relational) properties, and resemble in infinite ways. He needs real resemblance, which needs degrees of resemblance.
Gist of Idea
Hume does not distinguish real resemblances among degrees of resemblance

A Reaction
[compressed] See Idea 191. We forgive Hume, because he is a pioneer, but this is obviously right. Draw a line between 'real' resemblances and rest will be tricky, and bad news for regularity accounts of laws and causation.
