Almost at the end of the Cold War, arguably the most important natural law jurist of the West, John Finnis, published a very acrimonious and provocative essay in dialogue with the Christian theological morality and dogmatic tradition entitled “Nuclear Deterrence and the End of Christendom” (1988). In many respects, this essay speaks volumes to our present, but it also solicits new questions around limits that have been severely traspassed in the current atomic age headed towards extinction. It is worth noting that from the outset, Finnis reminds us how a fellow Catholic liberal theologian, Jacques Maritain in a lecture of 1955, claimed with surprising conviction that “America is today the area in the world in which…the notion of Christian-inspired civilization is more part of the national heritage than any other spot-on earth. If there is any hope for the sprouting of a new Christendom in the modern world, it is in America…” [1]. If this sounds completely analogous to the current program of “national conservatism” that today animates American political elites, defined by the ruthless attempt at the convergence of instrumental Christian vocation and political imperium, it is because these prophetic words have been thoroughly realized. 

Finnis does not hesitate to put his thumb on the theological monstrosity maintained by Maritain at mid century – although he does not say it explicitly, it is a concrete restitution of imperial Eusebianism decades before denounced by Erik Peterson in his famous essay on political monotheism – that by accepting nuclear deterrence as a form of uncontested ‘minor evil’ in face of the Soviet menace Christians were endorsing heretic positions at odds with the teachings of the Second Vatican Council. As Finnis argues, the logical structure itself of nuclear deterrence, precisely due to its affirmative promise to exclude “target populations”, fails to differentiate between combatants and non-combatants in an endgame that promises the potential massacre of innocent human beings [2]. This means, first and foremost, that nuclear deterrence (as well as its new preventive forms that have become normalized among global hegemonic powers) terrorize human communities as a direct public act of forthcoming devastation [3]. 

Even though Finnis does not stop to reflect about the notion of “public act”, it is very clear that this action, insofar as it is a linguistic act, aims at the effective cancellation of the possibilities of language and communication. Nuclear deterrence and proliferation are instruments that speak publicly, and that by doing so, it contributes to the atrophy of human language. As a rebuttal to Maritain’s celebratory artificial gnosis, Finnis sees in the language of nuclear deterrence coincides with the language of ‘utopia’ as a new absolutization of morality. This means that Maritain’s philosophical error – which Finnis calls the “theologian’s position”, since it also implicates an official sector of the Church – is to abandon practical reason of allocated goods (including human life) in the name of a comprehensive aim of building a civilizational “Christendom” coupled in a national community [3]. But whoever fully identifies the spiritual-providential realm with the political-legislative order is already at the mercy of an utopian project embedded in the sacrificial structure promoted by nuclear deterrence.

Towards the end of his essay, Finnis laments (implicitly repeating Karl Barth’s well-known 1930s essay but in an opposite direction) that the relationship between Church and State from the point of view of the atomic age and nuclear deterrence has now been completely altered. From now on, the atomic age demands a Christian vocation based on conscience. Specifically, Finnis calls for a position of refusal and minoritarian observance against the general options of radical evil: “The choice to reverence human life by refusing to participate in public choices to destroy it, is thus a choice is material of the Kingdom and has real and truly lasting effects…even when worldly wisdoms understand it only as a choice of greater evil’ [4]. And citing Cardinal Ratzinger, Finnis endorses the position of Christians as “belonging to a minority” finding courage in nonconformity within the normative order of social space [5]. The Finnis-Ratzinger’s position was still oriented by a Catholic commitment to dogmatics and public reason and virtue, which depends on the luminosity of the subject of religion. 

But the objection of conscience is a subjective reduction of modern secularization. In this sense, it might be pertinent to compare Finnis’ position to Ivan Illich’s own stance in the wake of nuclear testing in Germany in the 1980s, which he witnessed in “horrified silence…in order to make the horror visible” [6]. For Illich, who had come to see the triumph of civilizational mysterium iniquitatis in the institutional deformity of the conspiratio of the human species towards controlled subjectivity (conjutario) amounting to “intolerable realities”. The language of Christian prophecy is not the same as the language of silence, because only in the second we can become witnesses through the voice of pain and experience, because pain can uplift a contact with the world without redemption. As Illich made clear in his text “The Eloquence of Silence”, it is through the condition of silence that the word can become flesh and prepare a new life. It is very telling that in a later footnote to the essay in the 2011 edition, Finnis appears doubtful about the religious ground stating that: “Over twenty years later, the unsatisfactory state of Catholic teaching on the matter remains just as it was in 1988” [7]. What changed? At the end of the eighteenth century Novalis had noted that for any orientation of public reason in the West to materialize there needs to be a substrate of the divine mystery, but this is precisely the substrate that desecularization has effectively untied and obliterated from the public. A public where general annihilation percolates without restraints.
