St. Augustine

"Suppose, then, we were wanderers, and could not live happily away from our homeland, and that we felt wretched in our wandering, and wishing to put an end to our misery, determined to return home. We find, however, that we need transport, either by land or sea, in order to reach our homeland, the object of our enjoyment. But the beauty of the country through which we pass, and the very pleasure of the motion, charm our hearts, and turning these things which we ought to use into objects of enjoyment, we become unwilling to hasten the end of our journey; and becoming engrossed in a factitious delight, our thoughts are diverted from that home whose delights would make us truly happy. Such is a picture of our condition in this life of mortality".
