Full Idea
The question of values is more fundamental than the question of certainty: the latter obtains its gravity only on the presupposition that the question of value has been answered.
Gist of Idea
The question of values is prior to the question of certainty

A Reaction
I think that nowadays most people, and notably scientists, have given up the pursuit of certainty - so Nietzsche has won this battle. If values label what is important, then they are self-evidently the first question in any enquiry.
