It is a staple of liberal moral psychology, stemming from the ahistorical anthropological assumption of the individual preceding social formation, that man’s nature is an inherently self-interested one. Typically, the liberal arguments for the creation of social orders first presuppose some version of self-interest as an explanatory efficient cause. The various flavours of liberalism may qualify self-interest differently yet the core claim of the moral agent being principally motivated by that which is of most use to him holds true through most formulations.
Giambattista Vico’s argument against such a view of self-interested man begins from the quintessentially Aristotelian claim that the social order precedes man. Man, as seen from the liberal view, may ceaselessly act for what he takes to be personal particular ends, but said ends are ultimately are contingent upon the various institutional roles he occupies. When he is a father he identifies his interests with those of his kin; when he is a citizen he identifies them with those of his city; and when a national, with those of his nation.1 In each stage of social complexity, something new is disclosed about a given moral agent which makes what his interests are, intelligible. A man’s intentions fundamentally rest upon the social institutions which give his life meaning. Strip him of these and you lose the agent whose good you are inquiring into. So naturally, the verdict to be concluded upon regarding self-interest-itself is that it is a meaningless concept because there is no man, and has never been any man, that existed and developed outside of social orders or authorities of any kind.
If one is to identify pleasure with self-interest then, one must ask what kind of socialisation such a man has had to conclude that such a good is his primary good. Indeed if it is this masturbatory self-pleasure, this is the closest we get to pure self-interest, but such disposition in man can only come about after he is made to define himself against his social institutions, or is otherwise lead into such a life that deracinates him of his connection to the shared good of which his institutions allow him participation in. Historically, this process of individualisation is a product of political centralisation2, so we must also conclude that pleasure as self-interest is also artificial. One may indeed argue that in all such circumstances man desires principally his own welfare, but what it is that constitutes his own welfare is disciplined by his social order.
The fundamental question self-interest seeks to answer after all is, “why this good and not another?” Even if we were to posit man as this inherently hedonistic, desiring machine, he must still make that evaluative judgement between the various goods he may choose to enjoy. If he is intimately connected to his social institutions, he will use the role he plays in them as a chief factor in making such an evaluation. If he is disconnected, atomised, he will look elsewhere to other authorities, often nowadays without even identifying such agents as authorities, that will discipline him into desiring other goods. Such is the fate of the wage-slave who finds no fulfilment because he exhausts himself in a role that hardly serves as a true vocation. Naturally, he turns into a hollowed consumer. Yet even his existence as a consumer, as we see with consumers generally, ends up constructing new identities and loyalties which unifies him, and others like him, to corporate authorities.
Let us now consider the nature of the Good from Proclus. He argues that it belongs as a primary quality of God, the primal Good, to conserve all that exists. Likewise, if that which conserves – holds together the being of a multiplicity of things – is unity, then goodness, wherever present, makes the participant one, and holds its being together in virtue of this unification. Every good tends to unify what participates in it, and all unification is good in some manner.3
This gives us a very interesting manner in which to continue talking of social institutions and the human identification of goods. As we see from Vico above, it is this unification of the moral agent with the institution he is defined by that inebriates him with identification of goods which he sees as in his interest, but this can go much further than the individual. This ontological subordination of agent-to-institution is inherently good, as abused as it might otherwise be under advanced capitalist modernity and democracy, because it subsumes the individual good within the shared good.
Yet the logic of political and economic liberalism is always to lead away from unity and appeal to this mythic individualised self-interest, even if its success is predicated upon a more fundamental unity of which it exists in spite of. After all, it is the competitive logic of the market and of the electoral struggle – the institutional conflict between entities – not the cooperative logic of the unified social order that seeks internal goods which underlies both capitalism and democracy.
Unity allows for the development of grand projects; whether they be intellectual, artistic or political, they all depend on this homonoia to function. Insofar as it is unified, it is thus good, because it allows for such projects to flourish in an unfrustrated manner towards the interior goods of their respective practices.
Thus we can conclude in a Proclean fashion, as Vico himself does, that there is an inherently divine quality to the unity that allows for the flourishing of such shared projects. Vico identifies this divine quality with Providence itself. Unable to attain all the goods he wishes, man is constrained to pursue that which he is due, which is just. Any new set of institutional arrangements must always involve some manner of underlying agreement about the practices they make possible and the determinate content of this depends upon the inherited institutions of the historic social order. This regulating force of human justice, as Vico magnanimously declares; is divine justice which is administered by Providence to preserve social orders.4 That is how intrinsic authority is to human nature, which is to say, it is more fundamental than human nature itself. It is not for no reason that authors of the Gospels write that everyone is to be subject to the governing authorities, for there is no authority except that which God has established (Rom. 13) and that the faithful are implored to give all men their due, to;
