SUBJECTIVISM
Some subjectivist claims:
Moral realism is the claim that there are facts or truths about what is right and wrong that are prior to and independent of the beliefs and attitudes of appraisers.
Moral subjectivism denies that there are objective moral truths. It claims that moral judgments involve noncognitive attitudes. Subjectivism is not the view that moral demands are relative to circumstances or that moral judgments are relative to non-moral belief. The subjectivist thinks that moral judgments are only a matter of feeling. We should distinguish two version of subjectivism.
THE TROUBLE WITH SUBJECTIVISM
If moral deliberation and judgment is to tell people what they should
do, then it seems to presuppose moral standards that purport to be correct
independently of one’s beliefs or attitudes.
Also, the linguistic form of moral judgments does not fit the subjectivist analysis. Unlike expressions of attitudes, moral judgments are assertive in form. They ascribe properties to persons, actions, and institutions. Unlike reports of the speaker’s attitudes, moral judgments do not refer to the appraiser or his internal states.
SUBJECTIVISM AND DISAGREEMENT
Subjectivists often appeal to the fact that there is such a diversity
of moral opinion both within and especially across moral communities.
But convergence is not a precondition of objectivity. There are plenty
of disagreements about the correct interpretation of quantum mechanics
and about basic facts of cosmology. Creation scientists reject evolutionary
theory. Theists and atheists disagree. Sometimes the disagreement
is reasonable and sometimes it is not.
Also, we should be less inclined to question the objectivity of a domain to the extent that we can understand and explain lack of convergence. And there are many such resources for the moral realist to explain lack of convergence. One reason morality is contentious is that it often concerns matters of considerable personal and emotional importance, such as the appropriate distribution of the benefits and burdens of social and personal interaction. It’s not hard to see how various factors – such as personal loyalties, self-interest, or ideological commitments – could be potential forms of distortion, interfering with one’s tendency to track moral facts reliably.
In fact, moral disagreement actually undermines subjectivism. Consider again:
RELATIVISM AND TOLERANCE
Realism might seem objectionable if it commits one to dogmatism and
subjectivism may seem attractive if it underwrites tolerance. The
realist must think that his own moral beliefs are right and that his opponent’s
are wrong. But isn’t that dogmatism and doesn’t it breed intolerance?
By contrast, the implications of subjectivism might seem more reassuring.
If I am a subjectivist, I deny that there is a single true morality and
insist that moral judgments merely report or express noncognitive attitudes.
But then I cannot regard my moral opinions as better or more correct than
yours. So I should be humble and have no reason to interfere with
the moral beliefs and practices of others.
These arguments make several assumptions that are worth making explicit and addressing separately.
