Nicholas Rescher citations

“Leibniz … envisioned real possibility in terms rooted in axiological considerations of evaluative optimality. To be sure, it is clear that one cannot just optimize. … One has to optimize something, some feature or aspect of things. And if this factor is to be something that is qualified, be accepted as self-validating and self-sustaining, then the clearly most promising candidate would seem to be intelligence itself. … The value at issue here with "being for the best" is a matter of being so as intelligent creatures see it—that is from the vantage point of intelligence itself. Assuredly, no intelligent being would prefer an alternative that is inferior in this regard. And so, for an intelligent being—a rational creature—intelligence itself must figure high on the scale of values.”
