论道德愤怒的正当性

伦理学研究 2024年第2期 44-50页

作者：周谨平谭文中南大学人文学院

道德愤怒是一种有道德意义的情感,又隐含着不道德的风险。道德愤怒的困境在于道德判断的主观性、报复过度的威胁性、人际关系的阻碍性三个方面。要走出道德愤怒的困境,需要对道德愤怒进行严格限定,厘清道德愤怒的判断标准、行为准则和... 详细信息

道德愤怒是一种有道德意义的情感,又隐含着不道德的风险。道德愤怒的困境在于道德判断的主观性、报复过度的威胁性、人际关系的阻碍性三个方面。要走出道德愤怒的困境,需要对道德愤怒进行严格限定,厘清道德愤怒的判断标准、行为准则和人际交往意向。道德愤怒是基于正义感,反对不公平、追求公众福利的情感体验。唯有对这一情感进行有效规导,避免隐含的道德困境,才能保证道德愤怒的正当性。

近年来,中国农业过密化问题引起广泛的社会关注。本文基于黑龙江省农垦447户农户2018年的种植业调查数据,利用三阶段DEA模型测算农业过密化程度,并从土地经营规模视角进一步讨论如何纾解农业过密化。研究发现,现阶段黑龙江农垦农户的农业过密化均处于较高水平,其中,农药过密化程度最高,超过了40%,其他要素投入的过密化程度均在30%以上。基于不同土地经营规模农户的研究发现,大规模农户过密化程度最低,其次为小规模农户,中规模农户的过密化程度最高。为有效纾解农业过密化,本文认为中国农业应该走小规模精细化农业模式的道路,或进一步扩大规模,开展大规模农业经营模式,避免陷入中规模经营农业过密化陷阱。

1921年至1949年,中国共产党领导的婚姻伦理建设极大地促进了革命根据地婚姻道德关系的革新与进步,建立起男女平等、一夫一妻、婚姻自由的新民主主义婚姻伦理。大革命时期,早期共产党人开始将马克思主义婚姻伦理运用于对中国实际的分析,建立革命根据地后即确立并推行新民主主义婚姻伦理规范。抗日战争和解放战争时期,中国共产党又根据革命情势对婚姻伦理建设的方针措施作出灵活调整,以强化新民主主义婚姻伦理规范。中国共产党领导的婚姻伦理建设在新旧交替、复杂动荡的时代背景下展开,呈现出人文性与政治性相糅合、继承性与发展性相结合、前进性与曲折性相统一的基本特点。

近年来,美国推动实施“友岸外包”政策,使得全球供应链不确定性增加。为明确这一政策产生的影响,本文构建包含投入产出关联、劳动力迁移和资本配置的一般均衡模型,通过切断投入产出关联,增加非关税壁垒以及提高关税3种方式刻画“友岸外包”,量化评估实施“友岸外包”政策给中国和世界带来的经济成本。研究表明:平均而言,3种刻画方式下,中国消费者福利分别降低4.76%、2.74%和2.90%,而世界各国消费者福利遭受的损失分别为11.07%、1.34%和5.93%。机制分解表明,贸易量效应、贸易条件效应和要素配置效应是“友岸外包”经济成本的主要来源。反事实模拟结果显示,畅通国内大循环和国际循环将使“友岸外包”引起的福利损失分别降低27.09%和15.27%。其中,国内循环中要素市场一体化发挥的作用要大于商品市场一体化。此外,全面推动国内国际双循环可使“友岸外包”造成的福利损失降低43.80%。

本文主要探讨评价标记“你说”和“别说”的功能差异及成因。研究发现,二者差异主要体现在评价话语的信息结构、后续话语形式和语音停顿等方面,这些差异取决于二者语义功能的不同:一是评价对象不同;二是互动性不同。二者源结构在会话不同序列位置的不同用法,即“别说”处于引发序列的语用推理和“你说”处于回应序列的引述回应决定了二者功能的差异。本文最后总结出言者引发评论时使用评价标记“你说/别说”的条件。
