Hegel had complex views on the relation between ethics and religion, and his thought on these matters evolved over time. As a teenager, he was impressed by writers of the German moderate Enlightenment, and immersed himself in the literature of classical antiquity. He graduated from the Lutheran seminary at Tübingen (where his roommates were the future philosopher Schelling and the future poet Hölderlin), but was reportedly very critical of the way theology was taught there.
Hegel’s earliest work is principally concerned with religious and social themes. He develops a critique of what he there calls “positive” religion, which he sees as putting excessive emphasis on particular representations, doctrines, and institutional forms. As a source for spiritual renewal, at this stage he looks mainly to the classical Greeks. He does not yet share Schelling and Hölderlin’s enthusiasm for Kantian philosophy. But a bit later, he begins to engage with Kant, and to move away from his earlier more unconditional classicism. In the works of this period, he interprets the teachings of Jesus as anticipating Kantian ethics, while also emphasizing love as a fundamental motivator. Now he begins to interpret Christianity and Kantian philosophy as the two main elements of a major historic spiritual advance beyond what was achieved in classical Greek culture.
I take the Phenomenology of Spirit to contain the best statement of Hegel’s mature views in this area, and will save that for last here.
His later lectures on the philosophy of history are very accessible, but in some ways extremely misleading. In general, Hegel popularizes and simplifies a lot in his lectures. And while today his so-called Philosophy of History is the best known example of this old genre, it is very much a genre piece. “Philosophies of history” particularly dedicated to valorizing the contributions of the nascent German nation had become commonplace in Germany since the late 18th century. University professors were civil servants who were expected as a condition of their employment to contribute to what might uncharitably be called propaganda supporting German nationalism and its state-sponsored religion. The most notorious characteristics of Hegel’s Philosophy of History in fact have much more to do with this obligatory social context than with the distinctive philosophy that Hegel develops mainly in the Phenomenology and the Logic.
Overly simplified formulations in the philosophy of history lectures are the main source for very common but deeply mistaken claims that Hegel sees world history as straightforwardly governed by a single linear and universal teleological unfolding (e.g., of “the realization of the consciousness of freedom”) that is either ordained by God, or itself constitutes God. As someone very interested in the details of Aristotelian teleology, Kantian “internal” teleology, and Hegel’s use of them, I see such a simplistic and overly strong historical teleology as completely incompatible with the principles Hegel defends in his main philosophical works.
Hegel does indeed see genuine progressive development within history, and not a mere succession of accidents as Aristotle was more inclined to do, but contrary to the common stereotype, this does not constitute or correspond to a global development of “History”, as if Hegel thought that History were itself an independent thing in its own right in the Aristotelian sense. History is just a summation of many largely independent developments, a very weak form of unity. Even in the philosophy of history lectures, Hegel points out what he considers to be instances of retrograde development — from better to worse — such as the transition from the Greek world to the Roman world.
If history for Hegel had the strong unity claimed by the stereotype, this would be logically incoherent. But for Hegel himself it poses no problem, because he has no commitment to such a strong unity. He emphasizes that the independence of Aristotelian independent things is not absolute, but he agrees with Aristotle that it is with the independent things that we should be principally concerned, in our attempts to understand history as in anything else.
In the philosophy of history lectures, Hegel is polemically concerned to contrast the modern “German world” — as the embodiment of freedom, genuine community, and progress — with the old “Roman world” of imperial absolutism, bureaucratic administration, and negation of the individual. Martin Luther is presented as the original hero of the German world, and Kant as his successor. Luther’s founding gesture is interpreted as the assertion of the priority of individual conscience over institutional authority, and thus as consistent with moderate Enlightenment.
Hegel’s lectures on the philosophy of religion also aim primarily at an edifying popular presentation. There he among other things gives a sympathetic account of core elements of common Christian doctrine and symbolism, and eventually argues for the superiority of offenbare or “revealed” religion over other forms that he discusses with more limited sympathy. But at the same time, he seems to radically reverse the traditional understanding of revealed religion. For Hegel, offenbare means out in the open, intelligible in the light of day, not anyone’s private preserve. These again may seem to be compatible with the traditional meaning. But the kind of unconditional authority traditionally claimed for revelation is effectively ruled out by Hegel, who considers all appeals to unconditional authority to represent a low state of ethical development.
In some measure, what Hegel means by offenbare was Luther’s point too. Luther did after all translate the Bible to German so that more people could read it for themselves, and advocated that they do so. But for Luther, the text of the Bible is simply given to us by God as literal truth. He promotes a new direct authority of the literal text in the common tongue as a replacement for the mediating institutional authority emphasized by the Catholic Church. But for Hegel, no truth in the full sense of the word can depend on authority for its validation; the authority of a text can only derive from judgments about the content it articulates; and all such judgments could in principle be contested anew. Truth is a matter of intelligibility that should be understandable by anyone, never the special province of some particular authority. Hegel sees that behind emphasis on divine authority — as opposed to, say, goodness or love — lie strong claims on behalf of some human authority.
In Hegel’s Phenomenology, these issues are touched upon from multiple points of view. What corresponds to the later Roman world is particularly associated with the religious point of view of what Hegel calls the unhappy consciousness, which emphasizes the extreme transcendence of an eternal and infinite monotheistic God, while devaluing worldly life. In general, Hegel’s portrayal of this kind of religion is unfavorable. Yet the unhappy consciousness is also said to have a progressive aspect, insofar as its new notion of the infinite God potentially leads to a questioning of the ultimateness of all finite representations, and thereby also to a questioning of any representation that is supposed to be simply given to us. Hegel explicitly suggests that the development of “negative” theology in the new monotheistic setting of the later Roman world leads in principle to the questioning of finite representations.
Later in the Phenomenology, Hegel at length and in several stages criticizes what happens when purely individual notions of Reason are applied to these matters. First comes the naive activist who unilaterally judges everything in the world by her own principles, and finds the world to be lacking. In part this has to do with uncharitable interpretation, even though there also really are plenty of things that are wrong with the world. But the main problem with this point of view is its complete lack of Socratic self-questioning. It focuses simply on the vigorous assertion of one’s own conclusions. Though this does involve a glimmer of self-consciousness, it is only a glimmer. The essentially reflective character of what Hegel means by self-consciousness is fundamentally lacking.
Much later still comes the Kantian/Fichtean moral self, which has a much more reflective character, and recognizes that it is bound by duties. But this moral self is still limited to a strictly individual point of view on what ought to be universal. Hegel thinks that ultimately, even the best — most sincere and open-minded — unilateral moral judgment by an individual involves an untenable hubris (the excessive pride commonly highlighted in Greek tragedies). As Brandom points out, one of the great lessons of the Phenomenology overall is that moral judgment should not be unilateral — anyone judging someone else must also confess and ask for forgiveness. This should in turn make us more forgiving of others. For Hegel, moral judgment is the province of participation in the universal community of rational beings, under conditions of mutual recognition. Only thus can individual and narrower community prejudices be overcome.
In between, Hegel discusses the relations between Enlightenment and faith. Here he is mainly concerned to defend faith against overly broad or unilateral Enlightenment critiques that, e.g., simply identify religion with superstition or a conspiracy of priests and kings, as if it had no relation at all to ethics.
Toward the end of the Phenomenology, as a resolution of the issues he has pointed out with the alleged self-sufficiency of the Kantian/Fichtean moral self, he develops an account of the essence of religion as having to do most fundamentally with promoting mutual recognition in a community. As I put it before, religion and the notion of something greater than ourselves for Hegel play an essential role in keeping individual conscience honest. This applies not only to some ideal philosophical religion we might imagine, but also to concrete, imperfect historical religion in real communities. Hegel now suggests that in this way, even concrete historical religion, in spite of its reliance on particular representations, helps us to overcome the limitations inherent to the individual moral self.
In a final turn, Hegel argues that religion and philosophy are in a way concerned with the same subject matter. The difference is that religion as usually understood assumes and works from particular representations of what is universal, whereas philosophy for Hegel aims to approach the universal in a universal way, and in this sense constitutes the “truth” of religion. To approach the universal in a universal way for Hegel necessarily involves beginning from the concrete. But it also involves letting the thought of that concrete actively explicate itself through reflection, rather than attempting to ground it in something said to be simply given to us, or to be justified by pre-existing authority.
In more traditional language, I am tempted to say this amounts to treating something like a negative theology that nonetheless does not turn its back on the world as taking precedence over all positive theology that presupposes particular representations. Negative theology and its analogues hold that no positive assertions we are capable of formulating about the divine should, strictly speaking, be held to be true, but that the divine can nonetheless be approached by saying it is not this, and it is not that. Giving precedence to this over the positive theology that presupposes particular representations has generally not been regarded as an orthodox position (unless perhaps we consider certain schools of Buddhism), but it is one whose possibility is suggested by the very existence of something like a negative theology.
Historically, anything like a negative theology has usually been associated with very strong insistence on the transcendence of the divine. If by analogy we apply the term to Hegel (which to my knowledge he never did himself), it must be with the proviso that for him its object would not be a transcendence, but rather something like the ultimate ethical intelligibility of life (which, we might say in an Aristotelian way, of all things properly knowable by us “most deserves to be called divine”), viewed as compatible with the recognition that many things in life are not as they ought to be, and need to change.
