对于科学与宗教的关系问题,历史上曾发生过争论。从历史上看,科学与宗教是接续关系,从结构上看是转换关系。前者主要表现在西方数学源于宗教;在基督教的传统中分娩出了现代科学;以及中国道教的自然哲学是古典科学等三个方面。而后者则主要表现为:在现代,基督教由中心沦为边缘,而科学则成为新宗教,但科学与宗教仍将长期共处。另外,在对待科学与宗教关系问题上的“中国现象”有着极其复杂的原因。从科学的知识、活动、建制和文化等四个基本维度看它与宗教的对应关系,可知在文化多样性的时代,宗教对科学仍有多方面互补的意义,从前提性知识到价值目标,从方法论补充到社会规约等,双方形成了新的对话格局。新时代的科学应更加独立、民主和理性,并积极寻求与宗教及其他文化的多方面合作。

对于人类即将进入的“第二轴心期时代”,莱布尼茨的文化哲学具有重要的启迪价值。莱布尼茨是一个喜欢并善于调和与综合的哲学家。在莱布尼茨看来,世界文化是个多样性的整体,文化的他者有其不可替代的价值,知识与科学是文化统一的有力杠杆,中国文化是世界上最伟大的文化之一,它是欧洲文化的对手而非克星。因此,应当宽容平等地对待其他文化,文化各方不应是以哪一方压倒另一方而结束,而是通过各种力量的合理分配实现统一。人类文化的融合是一个必然过程,前定和谐、多样性统一和最终完满是文化融合的基本环节。多样性统一的文化观念源于莱布尼茨一向的哲学主张。欧洲文化传统及当时的社会形势为莱布尼茨提供了思想的温床。个人的独特经历和学术趣味为莱布尼茨文化哲学提供了个案基础。作为莱布尼茨本体论基石的单子范畴,除了自然属性外,也具有伦理和文化属性。由单子所构成的多样性统一的世界,为莱布尼茨文化哲学的建构奠定了系统坚实的思想基础。今天,全球的一体化更需要维护文化的多样性。人类应学会像莱布尼茨那样对待他者文化,正在和平崛起的中国也应对莱布尼茨的文化理想作出自己的回应。为了继续前进,“为了照亮我们这个时代的历史”,我们至少应有莱布尼茨那样的洞见、胸怀和信念。

人类文明因环境、资源和大规模杀伤性武器等问题的压力而遭遇到了前所未有的根本性危机,其根源则在于文明的底基是人之自然性的不断释放,以至于最终突破了地球的承载极限。因此,按照文明之U型总模式的进路,人类接下来的文明之旅必须“往回返”,其拐点即为第二开端。如同第一开端基于形而上学的哲学范式一样,第二开端也需要自己的哲学范式,而生态哲学则是新开端的第一哲学。建设第二开端的哲学必须重视和开发精神及其自由的文明价值,培养和塑造第二开端的人与文化。

人类社会从各民族和国家单一的历史向统一世界史的转变。使我们看待世界的方式发生根本变化,"整体论的复兴"即因于此。由于处境和视角不同,整体论表现出构成论、先验论和生成论的不同类型。这既是其不同构型,又是其历史上的展开形态。作为人类总体命运思考方式之一的全球伦理,即以一种构成论思路展示其"伦理之伦理"的特征。全球伦理的最大优长是真实、开放和突出全球价值,其难处则在扩展、具体推动者、宗教基础和终极目的方面。与之相对的天下体系选择了先验论的思路。它试图以中国原初时代的天下范畴来取代全球或世界概念,并通过"以天下观天下"的方式超越西方从民族国家看天下的思维,因而具有很强的形而上学建构力。只是这一思路既无法协调先验的天下公理与经验的帝国模型的边界对接问题,更无法保证"天下"不再成为霸权,因而最后留下的可能只是一种"天下神学"。全球伦理和天下体系的共同困境在于它们囿于还原论的限制。生成论不同于这二种思维而把人类的自我理解由宗教和国家批判引向文明的反思。从文明发展的"大逻辑"看,人类文明史大体经历了三个不同时期——暴力逻辑合法性的普遍化时期、资本的全球化时期和文明或自由价值的普遍化时期。这大体对应着整体论思维发展的三种形态:先验论——构成论——生成论。文明复兴的基本任务是重新修复已被阻断了的文化自调机制,以共筑的姿态生成和塑造一个新文明。而目前最紧要的,是在生成论的框架内把人们已有的共识组织起来,确立类思维、建构非同一性哲学和推动互美伦理等,以形成一个思考未来、引导实践的初步规范。

Fermented sour soup is a unique traditional sour food of the Miao and Dong ethnic groups in China. However， due to the commonly used traditional fermentation， the unstable fluctuation of microbial community often leads to some unpleasant inherent off-flavours in rice sour soup. In this study， the microbial composition and volatile flavour components of off-flavour and normal rice sour soup were examined by high-throughput sequencing (HTS) and headspace solid-phase microextraction coupled with gas chromatography-mass spectrometry (HS-SPME-GC-MS). Then， based on Pearson correlation coefficients， the correlations between fungi and bacteria and those between core microorganisms and key volatile flavour components were investigated. The dominant fungal genera included Candida， Dekkera， Pichia， Rhizopus， and Issatchenkia， whereas the dominant bacterial genera included Lactobacillus， Pectinatus， Bifidobacterium， Pseudomonas， and Acetobacter. Compared to normal rice sour soup， off-flavoured rice sour soup contained the significantly increased relative abundance of Candida and the significantly decreased relative abundance of Dkkera. In addition， 80 volatile flavour compounds detected in off-flavoured rice sour soup， mainly including esters， acids， and alcohols， were different from those detected in normal rice sour soup. Especially， some substances were only detected in off-flavoured rice sour soup， such as 1-hexanol (68-207 μg/kg)， butyric acid (20-91 μg/kg) and heptanoic acid (11-44 μg/kg)， which might be the main source of off-flavours. These results provide new ideas and strategies of removing or abating odour from fermented rice sour soup.
