Critically Assess the View That Ethical Judgements Should Be Based on Natural Properties or Nature
Critically assess the view that ethical judgements should be based on natural properties or nature
In this essay I will explain the idea of meta-ethics through ethical naturalism, part of ethical cognitivism and ethical non-cognitivism. I believe that ethical judgements cannot be based on natural properties or nature because I donât believe that anything is objectively right or wrong, and therefore âgoodâ, for example, doesnât have any natural properties (something objective that can be identified empirically) and so cannot be defined.
I will first approach ethical naturalism. Ethical naturalism claims that ethical statements can be translated into factual statements, and therefore can be verified or falsified. In other words, moral statements can be proved or disproved through empirical evidence. For example, saying âX killed someoneâ and âX is a bad personâ would both be viewed as factual information to the ethical naturalist, as they believe that through behaviour one can judge whether or not someone is a good person. In this case the behaviour of X killing someone has defined him or her as a bad person. However, does killing someone actually make you a bad person? What if X killed this person to save him or herself, or to save someone elseâs life? So killing someone doesnât necessarily define âbadâ. Now to say âX is a bad personâ means that you have made two presuppositions. The first being that it can be proven by empirical evidence, and the second that it is mass approved, i.e. something that is generally thought to be either right or wrong by most people, or it can be proved through a scientific method. Here all ethical statements are basically reduced down to statements of approval and disapproval.
However there are huge problems with this theory. The first, thought of by Hume, is that it isnât possible to get an âoughtâ statement from an âisâ statement. Ethical naturalists try to make âgoodâ and âbadâ etc. descriptive, rather than evaluative. Hume says that this isnât possible, if one person says âX is a bad personâ doesnât mean X is a bad person, nor does it mean someone else will say, âX is a good personâ. Ethical statements simply cannot be derived from fact because the former (ought) is evaluative and the latter (is) is descriptive. This exposes the fundamental philosophical flaw of ethical naturalism- that value judgements can be deduced from actual statements.
Humeâs law is backed up by Brandt, who expands on this idea. He says that the only time an ethical conclusion can be made from a statement is if the original statement had an ethical component in it to begin with. For example, if a certain act maximised happiness for all is seen as ârightâ, then in that specific situation, telling a lie to someone would be seen as ârightâ because it would maximise happiness for all
