No but it is, as alluded some time back, similar to the problem of infinite regress of dependent causes. It's the problem of infinite regress of be-causes. Without inherent value (no because needed), some axiom, self-evident truth, assumed to be true, etc., you have an infinite logical regress.
It's the limit of logic's conditionality.
Not that you have to reach it, but if you claim your values are all *purely* logic based...
So, what's an inherent value of a Paramecium?
