My father's note: “To be read with the Devil’s Eye, especially those within The Movement, however tangentially. Consider the potentials for barbarism… ‘The movement as Primitive Culture.’ PRIMITIVE CULTURE TOWARDS RATIONAL CULTURE, which has never been tried, never been tried. TOO LATE.”

There is no "rational culture". Culture is rationalized, one way or another. My parents even as self-described and committed humanists were never able to see the anti-humanism at the heart of their own dreams.
