Oh yea, he disavowed his own stuff a LONG time ago.. I’ll see what I can find on it.
His own kid committed suicide.

This says it wasn’t his child, but his grandchild who killed himself (ironically, perhaps, off the building at which his father worked so hard).
And there is NOTHING in here about him revoking his views. In fact, his 1994 ed. (pretty late!) has a whole other “explanation” apparently included.
Note the section on “permissiveness”. There is nothing in there describing just how Spock DID NOT believe in permissiveness. He only states that “fact”. Doesn’t give an example, even.
