If you are looking for a Kierkegaard primer, you won't do better for an easy way in than Clare Carlisle's admirable Kierkegaard: A Guide for the Perplexed.
And below is a nice quite from Søren Aabye himself -- quoted by Carlisle from Philosophical Fragments, but online at sorenkierkegaard.org:
But one must not think ill of the paradox, for the paradox is the passion of thought, and the thinker without the paradox is like the lover without passion: a mediocre fellow. But the ultimate potentiation of every passion is always to will its own downfall, and so it is also the ultimate passion of the understanding to will the collision, although in one way or another the collision must become its downfall. This, then, is the ultimate paradox of thought: to want to discover something that thought itself cannot think.
