Euthyphros dilemma...

[Angrboda]

Instead of this, the mind has inherent value because it has the essential attributes of life and love.

I don't see how claiming this to be true by fiat has any value.

The challenge remains unanswered. The concept of good has no meaning apart from the life of a knowing subject and that which is most to be desired. Without a concept of good no value system can stand. Meaning, value, and teleology have no place in either ontological or methodological naturalism. Turning to chemistry or evolution as a basis for value is a fool's errand.

So it's an argument from ignorance then, and therefore fallacious.
