[catalogued under 8. Modes of Existence / E. Nominalism / 2. Resemblance Nominalism]

Full Idea

'Blue' is vague by vague by some standards, for it has borderline cases, but that does not make it a family resemblance term, for all the shades of blue resemble each other in some respect.

Gist of Idea

'Blue' is not a family resemblance, because all the blues resemble in some respect

Source

Timothy Williamson (Vagueness [1994], 3.3)

A Reaction

Presumably the point of family resemblance is that fringe members as still linked to the family, despite having lost the main features. A bit of essentialism seems needed here.
