What Makes the Common Good Common?Key Points from Charles De Koninck1 Aquinas Guilbeau, O.P. In even the most capable philosophical hands, the common good remains a slippery concept. Its essence eludes the grasp of those who reach for it. This is due in part to the concept's complexity. "Common good" is composed of two rich, philosophically pregnant notions: goodness and commonness. Reflection on these two notions is ancient, of course. How a thing is good has preoccupied philosophers since the dawn of time. How a thing may be common has exercised philosophers less throughout history, but even the ancients recognized that the question of a thing's commonness remains as intricate as the question of a thing's goodness. Despite their long philosophical history, however, the notions of goodness and commonness evade quick and easy description. Because they represent elemental characteristics of being itself, they share in being's fundamental mystery. As a result, millennia of reflection have not exhausted these notions' meanings. Like being, goodness and commonness require careful study by each generation, so that its intellectuals and teachers might clarify these notions' remaining secrets. Thus does each generation contribute to the perennial philosophy. When we modern and post-modern thinkers try to describe the common good, and thereby grapple with its notions of goodness and commonness, we find one of these two notions more elusive than the other. Which of the two might surprise us. It is not the common good's goodness. [End Page 739] Despite the philosophical confusions of our age, we more or less still agree publicly as to what constitutes a good, and as a result what constitutes an evil. We deem health a good, for example, while we deem disease an evil. We embrace one as perfective; we repulse the other as destructive. To my knowledge, no one has yet extolled COVID-19 as a good. So, we moderns and post-moderns have not completely lost hold of reality. We still share a sense of goodness, even if our generation mislabels some evils as goods. When it comes to describing the common good, therefore, it is not the common good's goodness that eludes us. Rather, it is its commonness that we have difficulty grasping. What does it mean for a good to be common? How is a common good common? Are all common goods common in the same way? How is the example of health common? Is health a common good properly speaking, or does it only appear to be common? How do we know the difference? Is there a difference? Unfortunately, few of us can answer these questions well. The reasons may not all be our fault, but we should admit that, along with our secular contemporaries, we remain largely unversed in commonness. A sign of our inexperience with the concept is that we seldom ask questions about commonness. Instead, we take it for granted that we know what commonness involves. When pressed to describe it, however, we quickly discover just how uncommon understanding of commonness is. In the first half of the last century, Charles De Koninck was well aware of modernity's inexperience with commonness. He recognized that individualism and its philosophical prerequisites had so captured the popular imagination, even among Catholics, that the common quality of the common good was disappearing from view. As a result, political discourse—to say nothing of political life—had entered serious difficulty. Between the World Wars, De Koninck spoke up among Catholic philosophers to remind them of the "primacy of the common good," not simply as a practical concept but as a speculative one, in accord with its classical conception. De Koninck recalled for his contemporaries not only that but also how commonness, like goodness, is primarily something objectively real and metaphysically constituted, and only secondarily something subjectively perceived and practically useful. To revive the objective and metaphysical notions of goodness and commonness among Catholic intellectuals—many of whom had traded these for easier subjective and practical notions2—De [End Page 740] Koninck composed his famous essay The Primacy of the Common Good, Against the Personalists.3 In it, De Koninck spends eighty pages reviewing the objective...
