If the selection fails in that the subject fails to persist, natural selection is teleological and directed toward unfitness.
If this is a posteriori, remind Darwin of that.
The constancy of nature is its telos.
"If survival is the outcome of selection, natural selection is teleological and directed toward survival."
No, it isn't. It is directed toward nothing. It has no goal.
An outcome doesn't need a purpose or a goal; it just *is*.
" If the selection fails in that the subject fails to persist, natural selection is teleological and directed toward unfitness."
Natural Selection can never *fail*; it's a statement of what is. There is no goal.
