朱熹与郑玄关于《论语》3. 8章"素"与"绚"之"本末轻重"的对立,揭示出"礼的二重性":一方面,在理论上"礼"必然区分为不能被进一步还原的"素礼"(质)与"绚礼"(文)这两个面相;另一方面,在历史实践中"礼"又永远指向"文质彬彬"的整全之"一"。礼的二重性表明,虽然传统学术不太重视知性区分,礼的生活主要表现为伦理生活、政治生活、审美生活等的合一,但今天的人们依然能够从礼学中区分出(建立)独立意义的伦理学、政治哲学和美学等;另一方面,分门别类地建立起来的各种独立自主的学术传统,反过来又夯实和重建了中国传统的真美善的"合一"。

从横渠的“执喻失义”看“善的来源”问题

同海沤喻、水冰喻一样,横渠的“虚气”也是一种譬喻。在对横渠哲学的解读中,存在着“执喻失义”现象,争执即起。牟宗三与熊十力之争便是一例。两人的争执有四。一是横渠哲学究竟是与道家合流的“气一元论”还是儒家的“体用不二”,其“气”到底是“形上实体”还是“形下流行”。二是横渠哲学究竟是自然主义还是人文主义,其“神”到底是唯气论与泛神论合一所带出的光彩、质力不二还是超然遍、常、一的神体。三是横渠哲学究竟是人道空虚、唯任造化玩弄的境界论还是参赞神化、天人不二的实有论,其“虚空即气”到底是道家的“无能生有”还是儒家的“人代天工”。四是横渠哲学究竟是“阴阳不二”还是“心物不二”,其“心”到底是“浮明”还是“乾知”。这些争执相互融摄,让“乾坤互含”与“乾统坤”之间张力凸显,儒家的“善”的“来源”问题被追问。争论表明,“善”虽然是超越者,是超时空的常道,但也是人的作品,也自然、经验地得以确立。自然与自由,在横渠这里完成了合一。

如何为人类增强划界,以防范现代技术不断渗透并侵蚀人性的风险,是这个时代非常紧迫和尖锐的问题。在技术“之外”单凭某种“思”就为人类增强划定界线几乎是不可能的。要走出狭隘的“人民意识”,挺立人的主体性,必须正视人性的开放性和人自己创造自己生活的意义。这意味着人类增强的界线只有在“真正的、人本学的自然界”与“人的激情的本体论本质”那种合一中来划定,才是可能的。儒家“天工人其代之”的高远理想或许能够与脑机接口、人体外骨骼等现代新兴人类增强技术在理论上相互支撑。
