Einstein stated: "The significant problems we have cannot be solved at the same level of thinking with which we created them." The philosopher Martin Heidegger expressed the same thought this way: "All saving power must be of a higher essence than what is endangered, though at the same time kindred to it." He also said regarding technology on a global scale: "Only a God can save us."
