The Unabomber, Theodore Kaczynski, had a complex ideology that was primarily focused on opposing technological progress and modern industrial society. His views were outlined in detail in his manifesto, "Industrial Society and Its Future." Here are the key aspects of his ideology and what he was fighting against:
Anti-technology: Kaczynski believed that technological progress was destructive to human freedom and the natural world. He saw modern technology as a force that was increasingly controlling and limiting human behavior.
Critique of industrial society: He argued that industrialization had led to widespread psychological suffering, as people were forced to live in ways that were radically different from the conditions under which the human race evolved.
