马克思的自然观是空想社会主义学说、古典政治经济学和德国古典哲学三大知识传统综合创新的产物。“自然”概念在三大知识传统中发挥着奠基性的作用。空想社会主义把“自然权利”视为社会建构的尺度。古典政治经济学将现代社会分工体系看作满足人们“自然需要”的必要手段。德国古典哲学将“自在自然”理解为主体反思的起始环节。马克思自然观上的创新呈现为三条回环相扣的批判线索。其一是吸收古典政治经济学对社会分工的解剖,进而突破“自然权利”中私人利益与公共利益永恒对立的理论预设。其二是贯彻德国古典哲学对自在之物的批判,进而指认出“自然需要”观念在认识论意义上的局限性。其三是回溯空想社会主义的人本学唯物论源头、承继古典政治经济学解剖现代社会的理论构想,进而把德国古典哲学中思辨的自然观转化为对于“人化自然”的现实的批判。在此基础上,马克思最终确立了以人化自然为前提、以历史化了的自然为具体认识起点的辩证自然观。马克思的自然观为当代生态文明建设确立了科学的本体论根基、价值论立场和实践论导向。

The interaction between sites A, B and X with passivation molecules is restricted when the conventional passivation strategy is applied in perovskite（ABX3） photovoltaics. Fortunately, the revolving A-site presents an opportunity to strengthen this interaction by utilizing an external field. Herein, we propose a novel approach to achieving an ordered magnetic dipole moment, which is regulated by a magnetic field via the coupling effect between the chiral passivation molecule and the A-site（formamidine ion） in *** strategy can increase the molecular interaction energy by approximately four times and ensure a well-ordered molecular arrangement. The quality of the deposited perovskite film is significantly optimized with inhibited nonradiative recombination. It manages to reduce the open-circuit voltage loss of photovoltaic devices to 360 mV and increase the power conversion efficiency to 25.22%. This finding provides a new insight into the exploration of A-sites in perovskites and offers a novel route to improving the device performance of perovskite photovoltaics.

高度复杂的全球化与逆全球化浪潮相互交织,形成了我们必须面对和应对的实际性;这种实际性以敞开的方式把价值提供给人类,也以隐蔽的形式把风险和代价抛给我们。从工业主义时代到当今智能化时代,新兴技术给予现代风险以变革性的传播力度和范围,自然风险让位于人为风险,单个本土性的风险极易演变成全球范围内不可控的叠加风险。随着当今算法技术越来越深入地渗透到个体日常生活和社会治理领域,出现了一种新型的算法风险和垄断性的算法权力,它危及个体的自主能动性、身份认同乃至集体行动的实践能力。由贝克和吉登斯发展起来的“风险”和“风险社会”概念并不是纯粹价值中立的描述性词项,而是隐含了一个规范性预设:支配风险分布和分配的权力结构对个体和集体的自主能动性带来不应得的伤害。一方面,我们可以借鉴贝克—吉登斯的风险社会框架去理解算法风险的性质;另一方面,我们也需要突破这一框架,在自主能动性的规范性层面为理解和范导算法风险和算法权力提供一个可证成的伦理批判。
