Full Idea
How shall we prevent a sorites taking us to the conclusion that a chair might have originated in a completely disjoint lot of wood, or even in some other material altogether?
Clarification
A 'sorites' is a slippery slope
Gist of Idea
If a chair could be made of slightly different material, that could lead to big changes

A Reaction
This seems a good criticism of Kripke's implausible claim that his lectern is necessarily (or essentially) made of the piece of wood it is made of. Could his lectern have had a small piece of plastic inserted in it?
