"We are tempted, indeed in a consumer culture encouraged, to reduce life to a simple search for happiness. Happiness, however, withers if there is no meaning. The other temptation is to disavow the search for happiness in order to be faithful to that which provides meaning. But to live only for meaning—indifferent to all happiness—makes us fanatic, self-righteous and cold. It leaves us cut off from our own humanity and the humanity of others. We must hope for grace, for our lives to be sustained by moments of meaning and happiness, both equally worthy of human communion. And it is this grace, this love, which in our darkest moments allows us to endure."
