It is a wonderful thing to see a first-rate philosopher at prayer. Tough-minded thinking and tenderhearted reverence are friends, not enemies. We have for too long separated the head from the heart, and we are the lesser for it. We love God with the mind and we love God with the heart. In reality, we are descending with the mind into the heart and there standing before God in ceaseless wonder and endless praise. As the mind and the heart work in concert, a kind of "loving rationality" pervades all we say and do. This brings unity to us and glory to God.
-Søren Kierkegaard, The Prayers of Soren Kierkegaard, “Reflections”
