Well, values presuppose an alternative. Only living organisms face an alternative. So, unless your art is an expression of plant or animal values (can’t think of a single example, feel free to provide me with one), it’s an expression of human values. And human values are ethical values. That’s what Ethics is, the study of human values.
Or maybe your art is not an expression of values at all. Not sure what it’s good for then (well, I am, actually: it’s not good, by definition).
If by metaphysical values you are referring to a sense of life, I don’t think just saying “metaphysical values” is going to communicate that to someone. I head to go asearchin’ too.
Besides, the only distinction between personal moral values and what you’re referring to (if this is what you’re referring to) is in scope. Personal values refer to what is good and important for the individual, “metaphysical values” to what is good and important for man in general.
The “metaphysical value-judgments” Rand wrote about are what the artist personally holds to be “regarded as essential, significant, important” - about existence. These, naturally, can be good - or not - for men.
“An artist does not fake reality - he stylizes it. he selects those aspects of existence which he regards as metaphysically significant - and by isolating and stressing them […] he presents HIS view of existence.”
[Art and Sense of Life, RM]
So, in his creation, from the conceptual to the perceptual, abstraction to concrete, he is guided by his value-judgments, is my understanding.
"Cognitive abstractions are formed by the criterion of: what is ESSENTIAL? [Epistemologically, regarding the class of existents.]
Normative abstractions are formed by the criterion of: what is GOOD?
Esthetic abstractions are formed by the criterion of: what is IMPORTANT?"
[AR]
I think an artist’s ‘m-v-j’s’ and his ‘sense of life’ get mixed up too easily in discussions. “(A sense of life is a pre-conceptual equivalent of metaphysics, an emotional, subconsciously integrated appraisal of man and existence.)”
and also:
“A sense of life is NOT infallible. But a sense of life is the source of art, the psychological mechanism which enables man to create a realm such as art.”[AR]
They are closely related, but can often be contrasting and opposed, I think. Loosely speaking, such would
be an artist with “mixed premises”, I reckon.
