External goods are the goods that practices can produce but that are not unique to them — money earned through chess could equally have been earned through poker; prestige achieved through medicine could equally have been achieved through politics. MacIntyre's distinction matters because external goods are the only goods that institutions and markets can reliably recognize, and because AI has a particular efficiency at producing them. When a technology amplifies external goods without amplifying internal goods, the ratio between the two shifts, and the incentive structure that sustains practices is progressively eroded. The accumulation of external goods without internal goods is the structural signature of the pathology MacIntyre calls institutional corruption.
External goods have three features that distinguish them from internal goods. First, they are objects of competition — the more one person has, the less there is for others. Second, they can be obtained through any number of activities, not only through the practice that might happen to produce them. Third, they are visible to markets, institutions, and measurement systems in a way that internal goods are not. These three features together make external goods the natural currency of institutional life, and they explain why institutions that were established to serve practices tend, over time, to become oriented toward the external goods that their practices produce.
The Trivandrum training described in The Orange Pill illustrates the asymmetric amplification of external goods. Twenty engineers with Claude Code produced twenty times the output they had previously produced. The external goods — shipped features, solved problems, measured productivity — multiplied with the arithmetic precision the productivity metric promised. The internal goods — the diagnostic intuition built through thousands of hours of patient engagement, the taste that distinguishes between solutions that merely work and solutions that are genuinely elegant — did not multiply. They could not, because internal goods are not the kind of thing that amplifies with tool use. They require the practice itself.
Alex Finn, also described in The Orange Pill, built a revenue-generating product without writing code by hand. He obtained the external goods of software development — a working product, revenue, professional recognition — in a fraction of the time previously required. Whether he obtained the internal goods of software engineering is a question the celebration of his achievement does not pose, because the vocabulary within which the celebration is conducted does not contain the category of internal goods.
The danger is not that external goods are amplified; external goods have always been necessary to sustain practices, and their more efficient production is often welcome. The danger is that the dissociation of external goods from internal goods — the possibility of obtaining the one without the other — undermines the incentive structure that previously made the cultivation of internal goods worthwhile. Why should a young developer undergo the discipline of learning to feel a codebase from the inside when the external goods of software engineering are available without that discipline? The market gives a clear answer: she should not. The market's answer is correct within its own frame of reference and catastrophic as a guide to what kind of practitioners we should become.
MacIntyre introduces the concept in After Virtue alongside internal goods, drawing on Aristotelian and medieval distinctions between goods pursued for their own sake and goods pursued as means to further ends. The distinction has been developed in contemporary virtue ethics by Shannon Vallor, Joseph Dunne, and others.
Competitive structure. External goods are necessarily scarce — more for one means less for another — producing the winner-takes-all dynamics that characterize market competition.
Practice-indifferent. External goods can be obtained through many different activities, including activities that are not practices at all.
Market-visible. The metrics by which institutions measure their own performance track external goods because these are the goods markets can price.
Amplification efficiency. AI has particular efficiency at producing external goods, creating the dissociation from internal goods that undermines practices.
Necessary but insufficient. External goods are necessary for sustaining practices but become corrosive when the pursuit of external goods displaces the pursuit of internal goods.
Whether markets can be redesigned to recognize internal goods, or whether the market's invisibility to internal goods is constitutive of what markets are — the latter view, defended by MacIntyre and by critics of neoliberal political economy, implies that markets will always create pressure against practices, and that the defense of practices requires non-market institutions.
