A new study suggests that concussions and head trauma can cause degenerative diseases similar to A.L.S. and that Lou Gehrig may not have had Lou Gehrig's disease.
I wonder what the experimental philosophers are going to say? It certainly does look like the authors of the study are with Kripke. Upon coming to doubt that Gherig had A.L.S., they didn't say that they had evidence that A.L.S. isn't Lou Gherig's disease, they said that they had evidence that Lou Gherig had neither A.L.S. nor Lou Gherig's disease. Maybe the experimental philosophers will do a cross cultural study to look for non-English speaking doctors willing to describe the results as evidence that Lou Gherig's Disease is actually a degenerative disease similar to but distinct from A.L.S. often caused by concussions and trauma.
