His journal entries are antecedent to your 1965 conversations, so maybe he did eventually come to conclusions.

I'll definitely be interested to read what you write. I'm also certain I do not know the full story. How does a man go from a humanistic/transpersonal psychologist focused on self-actualization and transcendent experience, talking about how everyone has peak experiences, to discussing outright eugenics murder? That's a hell of a shocking transition.

I gotta say, it's kinda disturbing to hear you say Maslow's thinking about humans was so heavily informed by the behaviour of farm yard chickens. What on Earth would make him think that he could generalize chicken behaviour in captivity to human behaviour in complex modern human environments? It is a pretty, pretty big leap...
