Two Concepts of Dignity for Humans and Non-Human Organisms in the Context of Genetic Engineering

The 1992 incorporation of an article by referendum in the SwissConstitution mandating that the federal government issue regulations onthe use of genetic material that take into account the dignity ofnonhuman organism raises philosophical questions about how we shouldunderstand what is meant by ``the dignity of nonhuman animals,' andabout what sort of moral demands arise from recognizing this dignitywith respect to their genetic engineering. The first step in determiningwhat is meant is to clarify the difference between dignity when appliedto humans and when applied to nonhumans. Several conceptions of humandignity should be rejected in favor of a fourth conception: the rightnot to be degraded. This right implies that those who have it have thecognitive capacities that are prerequisite for self-respect. In the caseof nonhuman organisms that lack this capacity, respecting their dignityrequires the recognition that their inherent value, which is tied totheir abilities to pursue their own good, be respected. This value isnot absolute, as it is in the case of humans, so it does not prohibitbreeding manipulations that make organisms more useful to humans. But itdoes restrict morally how sentient animals can be used. In regard togenetic engineering, this conception requires that animals be allowedthe uninhibited development of species specific functions, a positionshared by Holland and Attfield, as opposed to the Original Purposeconception proposed by Fox and the Integrity of the Genetic Make-upposition proposed by Rolston. The inherent value conception of dignity,as here defended, is what is meant in the Swiss Constitution article.     

Genetic engineering and the dignity of creatures

The Swiss expert report suggests that the inherent dignity of a living being be identified with its inherent value. But the phrase “inherent value of a living being” seems to connote two concepts of inherent value. One has a morally obligating character but is counterintuitive because of its egalitarianism. The other is one of non-moral value. It is more compatible with considered intuitions but insufficient for substantiating the expert report’s claim that human beings have moral duties towards animals and plants. The paper discusses these concepts. Consideration is then given to the problem of how discursive support can be generated for the expert report’s claim that human beings have the moral duty to abstain from impairing those functions and abilities of a non-human being that members of its species as a rule can practice.

大型厂房消防安全设计评估

借鉴国际性能法规发展的经验,跟踪国际火灾科学研究前沿,着手研究和建立适用于我国新的建筑防火设计规范体系,已成为我国消防现代化建设的重要战略任务之一。作者以具体实例为对象,分别采用处方式和性能化设计方法进行建筑防火设计评估,演示两者设计过程和设计理论的差异。本文将是一组文章之一,针对一个大型边间厂房的具体设计按照处方式法规进行了评估,文章鉴别设计中不符合现行规范的条款并按规范提出修订方案,其阐述和讨论结果可为进一步进行火灾安全性能设计提供参考。有关的性能设计分析将在另一篇文章中详细介绍。
