Bob I watched several minutes of the video and formed an opinion that was neither in favor or against his opening statements.
My thought was that again we have differences on language and the assumptions that are drawn as the basis for the discussion. There again this is neither pro or con, but the use of a subset of a language(science) to frame a context that for the speaker is valid but not to everyone in the extended group.
I wish to point out that even if every thing that he said was a valid argument the other video that I referred to about music and the communication with someone that the baseline of society disallows as a member shows that for mentally disabled, his language context can not be reconciled with the moral/science debate. My conclusion is that as most things like that it sounds interesting but is revelation's to a select group is like a tree falling in the forest, only if the tree hits me in the head does it matter.
