"Unless one supposes that all human powers are irremediably subverted by the Fall, that there has been a complete corruption of human nature, there will always be some instinct in that nature, however weak, which is oriented to reality and therefore oriented to these basic qualities of reality: truth, goodness, unity, and beauty. Also there is, of course, always the possibility that the grace of God is at work in uncovenanted ways in human hearts and situations, so that those instincts can be assisted by grace to respond to the divine presence in the Creation. This is what it ultimately comes down to."
