莱斯认为自然危机的根源在于控制自然的观念;控制自然的实质在于控制人;科学技术已成为控制自然乃至控制人的工具;只有依靠伦理和道德的进步才是解决自然危机的根本出路。莱斯的控制自然思想对人类解决生态危机具有一定启示,但其控制自然的思想存在着理论上困境。 Rice believes that the root causes of natural crises lie in the idea of ​​controlling nature; the essence of controlling nature lies in controlling people; science and technology have become tools for controlling nature and even controlling people; and only by virtue of ethical and moral progress is the fundamental solution to natural crises. Rice’s thought of controlling nature has certain enlightenment to mankind’s solution to ecological crisis, but there are theoretical difficulties in his thought of controlling nature.
