The way I look at it moral values as well as aesthetic ones fall into two
categories: Williams' thick and thin notions. The thin notions like right
and wrong, good and bad do not fall under the scope of moral realism. They
are too vague.
It is the thick notions that are the interesting ones. Examples are
Brutal, courageous, tacky. These notions denote what I would term moral
properties. The only way you can explain to someone what it is to be
brutal or commit a brutal action is to show them an example of brutality.
You can't break this term down any further.
In an Aristotelian fashion, people learn what it is to be brutal by forming
connections when shown sequences of brutal things. The fact that something
is brutal entails that is wrong and by making the connection enough times
from being exposed to it, we get moral learning.
A philosopher called Mccdowell claims that moral values are like colours.
They have secondary objectivity. This means that they are not independent
of perception itself but they are independent of any particular person's
perception. A sound needs the ability of a sense of hearing to be heard
but not necessarily mine or yours to be heard. My view goes one step
further to claim that moral values have primary objectivity and do not rely
on perception at all. We are exposed to moral properties which can be
ascribed to actions just as other non-moral properties and these have an
effect on us. Thick notions do not need to rely on our sense of perception
to continue to be moral properties just as a square does not rely on
perception to continue to still have its property of squareness.
This type of resemblance nominalism, how ever convincing still falls
prey to a vicous
and fatal regress, the idear that by recognizing a thing as being of a
certian type by referance to a group of exmplar items, mmmmm, but what
identifys these things as being part of the exmlpar group.
to put it simply to say that somthing is red simply because it
resembales other red things, in virture of what do those other "red"
things qualify as being red? by referance to a higher order of red
things, and so on Ad infinitum? :-(
