Skepticism is to cynicism as doubt is to...?

Truth is to fact as faith is to knowledge as hope is to optimism. You can know a fact; you can only glimpse a truth. A fact is like a stick of lumber. Complete, nailed down, utilitarian. You can turn it over and pass it around and examine it from every angle. But a truth is alive, a cool toad between cupped palms. You just barely get to peek at it through a gap between your fingers. Open too wide and it’s gone. Squeeze too tight and you kill it. And it will more than likely pee in your hand.
