The use of other animals for human purposes is as contentious an issue as one is likely to find in ethics. And this is so not only because there are both passionate defenders and opponents of such use, but also because even among the latter there are adamant and diametric differences about the bases of their opposition. In both disputes, the approach taken tends to be that of applied ethics, by which a position on the issue is derived from a fundamental moral commitment. This commitment in turn depends on normative ethics, which investigates the various moral theories for the best fit to our moral intuitions. Thus it is that the use of animals in biomedical research is typically defended by appeal to a utilitarian theory, which legitimates harm to some for the greater good of others; while the opposition condemns that use either by appeal to the same theory, but disagreeing about the actual efficacy of animal experimentation, or by appeal to an alternative theory, such as the right of all sentient beings not to be exploited. Unfortunately, the normative issue seems likely never to be resolved, hence leaving the applied issue in limbo. The present essay seeks to circumvent this impasse by dispensing altogether with any moral claim or argument, thereby cutting the Gordian knot of animal ethics with a meta-ethical sword. The alternative schema defended is simply to advance relevant considerations, whereupon "there is nothing left but to feel." In a word, motivation replaces justification.
将其他动物用于人类目的是一个极具争议的问题,在伦理学中也是如此。之所以如此,不仅是因为对此类用途存在着激烈的支持者和反对者,而且还因为即使在后者中,他们对反对的理由也存在着坚决的、截然相反的分歧。在这两种争论中,所采取的方法往往是应用伦理学,通过这种方法,对这个问题的立场是从一个基本的道德承诺中推导出来的。这种承诺反过来又取决于规范伦理学,它为我们的道德直觉调查各种道德理论,以找到最佳契合点。因此,在生物医学研究中使用动物通常是通过诉诸功利主义理论来辩护的,该理论为了更大的利益而合法化对某些人的伤害;而反对者则要么通过诉诸同一理论来谴责这种使用,要么不同意动物实验的实际效果,要么诉诸替代理论,例如所有有感知能力的生物都不应被利用的权利。不幸的是,规范问题似乎永远无法得到解决,因此应用问题陷入了僵局。本文试图通过完全摒弃任何道德主张或论点来规避这一僵局,从而用元伦理学的利剑斩断动物伦理学的戈尔迪乌姆之结。所捍卫的替代方案只是提出相关的考虑因素,然后“除了感觉之外别无他物”。换句话说,动机取代了理由。
