Most of us live primarily in the everyday mode, where we have ordinary thoughts and feelings that accompany our engagement in ordinary activities such as working, eating, paying bills, driving, sleeping, exercising, and shopping. Even when we are with friends and family members, most of our thoughts, feelings, and actions are of the everyday variety. However, there are certain moments, rare and ephemeral though they may be, where the everyday mode of life is unexpectedly pierced and where some kind of (...) difficult-to-explain experience of lifting or transcendence occurs. Often these moments of lifting or transcendence are triggered by the awareness of beauty – for instance, the beauty of a song, a story, a beach, or a green field. And often these moments have a wistful quality. Though they are deeply fulfilling and, indeed, are more fulfilling than any of the moments that we experience in the everyday mode of life, they are nevertheless tinged with disappointment in that (a) they do not last and (b) they seem to point beyond themselves to something even better, but which seems just out of reach. C. S. Lewis took these moments to be intimations of heavenly existence, and he thought that they revealed to us that we have an inborn desire for heaven – and, with it, God. Lewis referred to this inborn desire as Joy (always with a capital “J”), and in different writings he advanced the argument from desire; that is, he argued that our inborn desire for heaven and God provides us with evidence that heaven and God exist. Though Lewis is probably more closely associated with the argument from desire than anyone else, there are others who are closely associated with this argument, notably, Aquinas. In this chapter I will examine the argument from desire, and while doing so I will often focus on points that Aquinas and Lewis have made. (shrink)
