伦理思想作为安·兰德客观主义哲学思想的关键,其目前的研究现状可以从研究内容和研究方法两个方面来分析。研究内容上聚焦在总体特征、政治伦理思想、女性伦理思想以及商业和教育伦理思想等方面;研究方法上主要有阐释研究、论证研究和比较研究。总体而言,目前对兰德伦理思想的研究不足与局限在于:批评内容的狭窄和肤浅,批判方法的缺乏,以及批评态度的两极化。 As the key of Ann Lland’s philosophy of objectivism, the current research status of ethics can be analyzed from two aspects: research content and research methods. The content of the research focuses on the aspects of overall characteristics, political ethics, female ethics and commercial and educational ethics. The research methods mainly include interpretation research, demonstration research and comparative research. In general, the current research on RAND’s ethics is not enough and limited in the following aspects: the narrow and superficial content of criticism, the lack of critical methods, and the polarization of critical attitude.
