「友谊藉着对恩惠的报答而得以维系。」
《神学大全》IIa-IIae，第106题，第2条
“Per recompensationem beneficiorum amicitia conservatur”
Summa theologiae IIa-IIae q. 106, a. 2
阿奎那指出，友谊藉着对所受恩惠的感念而得以维系。首先，我愿向公教神学手册协会（L’Associazione Manuali di Teologia Cattolica，AMATECA）的理事会致谢，感谢他们盛情邀请我参与这项重要的神学计划。特别感谢John Janaro先生与Lisa Lickona女士对书稿提出有益的意见，也感谢Susan Needham女士在英文版的筹备过程中给予慷慨的协助。耶稣会的John McIntyre神父以明快睿智的文字为本书的德行研究作序，我很高兴在此表达我的感激。我将本书献给Thomas Dominic Rover神父，首先是为了向这位道明会弟兄致以深深的谢意，因为最初教导我认识真理与友谊的，正是他。
Friendship, observes Aquinas, is preserved by the acknowledgment of a favor received. First of all, I would like to express my appreciation to the governing board of L’ Associazione Manuali di Teologia Cattolica (AMATECA) for the kind invitation to participate in this important theological project. Special gratitude goes to Mr John Janaro and Mrs Lisa Lickona for providing helpful observations about the manuscript, and to Mrs Susan Needham for her gracious assistance in preparing the English edition. For introducing this study of the virtues with his intelligently lithe prose, I am happy to acknowledge my indebtedness to Jesuit Father John McIntyre. And by dedicating this book to Father Thomas Dominic Rover, I want above all to recognize with profound gratitude the Dominican brother who first instructed me about truth and friendship.
