In the late '60s, Hundertwasser delivered a number of nude speeches in which he denounced rationalist architecture and pledged to free people from the "godless" straight line that had become pervasive with the rise of modernization and industrialization. In an essay titled "There are No Evils in Nature. There are Only Evils in Men," he called for a return to a more organic lifestyle, "When man thinks he has to correct nature, it is an irreparable mistake every time. A community should not consider it an honor how much spontaneous vegetation it destroys; it should rather be an honor for every community to protect as much of its natural landscape as possible." When creating a building, Hundertwasser was also careful to offset the destructive aspects of construction with regenerative environmental measures.
