It is not enough to present the wisdom of love as a credible line of thought; the text must also leave the reader with a renewed sense of being in touch with the most compelling component in human life. It must move the heart as well as the mind. If, however, my writing elicits only an emotional response, I will have failed to trace the influence of love as it presses its way into every aspect of human existence-not only in personal relationships in families and faith communities, but in business and the military establishment as well.
