More on Ellul, and yet more...
"The Unabomber borrowed heavily, says Foster, especially from the writings of Jacques Ellul. It was in February 1965 that American readers were first introduced to Ellul's Technological Society in that magazine. Kaczynski wrote his brother David that he was deeply impressed by Ellul's writings which closely mirrored his own beliefs. These ideas pop up all over Kaczynski's writings, letters and manifesto..."
Ellul is also referenced in the first memo of The Illuminatus Trilogy... hmmm....
Some of Ellul's writing is available online here
