性伦理的研究需要回答三个基本问题:其一,性是否有关善恶?这个问题的关键在于性行为能否成为道德价值的客体。显然,我们认为人的性行为是有意识、有目的且具有社会利害关系的行为,理应受到道德的评判。其二,对性行为是否有特殊的道德要求,即性道德是否必要?我们认为性行为不只是要受到一般社会道德规范的约束,还要受到以“爱”和“忠贞”为基本内容的性道德的要求,这是基于人格完善和社会和谐的道德需要而提出的道德要求。其三,性道德需要法律强制吗?我们认为,当性行为损害到公共利益的时候,法律当然可以强制实施性道德,但由于法律强制的社会成本和经济成本太大,所以动用法律强制需要特别谨慎。 The study of sexual ethics needs to answer three basic questions: First, whether sexuality is related to good or evil? The crux of this question lies in whether sexual behavior can become the object of moral values. Obviously, we think that human sexual behavior is a conscious, purposeful and socially interested act that deserves moral judgment. Second, is there any special moral requirement for sexual behavior, that is, whether sexual morality is necessary or not? We think that sexual behavior is not only restricted by the general social moral norms, but also subject to “love” and “loyalty” as The basic moral requirements of the content, which is based on the moral needs of personality and social harmony put forward the moral requirements. Third, does sexual morality require legal coercion? We think that when the sexual act harms the public interest, the law can of course enforce sexual morality. However, because of the compulsory social and economic costs imposed by law, the use of legal coercion requires special cautious.
