Why Habermas Must Be Discussed Next

Note:

Since first draft of the book and this article were written, Jürgen Habermas has died.

He was the most significant living representative of the Frankfurt School tradition of critical theory, and his legacy of work spans what may be the broadest range of philosophical territory any contemporary thinker has probably ever attempted: from philosophy of language and action theory to moral and political philosophy to the analysis of modernity and its pathologies.

His discourse ethics, developed most fully in Moral Consciousness and Communicative Action (1983) and elaborated across decades of subsequent work, is one of the most systematically worked-out attempts in contemporary philosophy to ground moral validity in something other than either tradition or unmediated structural facts.

The first thing to say about Habermas' work is that reading him is work. I say this not to whine but to set up what I think is genuinely at stake between his project and this one, because the resistance inherent in reading Habermas is not incidental to what he is actually trying to do. It reflects a very specific philosophical wager: that the most important moral and political questions are ones whose answers can only be justified through a particular kind of discourse, and that getting the discourse right is therefore the central philosophical task.

I personally think that wager is wrong. Or more precisely, I think it is right about a narrower range of moral reality than Habermas takes it to cover, and mistaken to the extent that it treats that range as the whole. Let me explain myself.

What Habermas Actually Did

Habermas's discourse ethics emerged from a specific problem. By the late 1970s, moral philosophy in the analytic tradition was stuck in arguments between utilitarianism and various forms of Kantian deontology, with neither side able to ground its claims in anything more solid than intuition. Continental philosophy, meanwhile, had mostly just given up on the grounding project entirely, following Nietzsche or Heidegger or various forms of post-structuralism into positions that were philosophically very interesting, but useless for anyone trying to actually defend claims about what was right or wrong.

Habermas saw a way through. The way was not to ground morality in some metaphysical fact about the universe, or in the structure of pure practical reason, or in the maximization of welfare, but to ground morality in the conditions of communication itself. When we speak to one another with the intent of reaching understanding, we implicitly raise validity claims that have to be redeemable through argument. We claim what we say is true, or right, or sincere. These claims are built into the very structure of any communication oriented toward understanding, not optional features of particular kinds of discourse.

From this observation, Habermas argued that moral validity could be located in what could in principle be justified through practical discourse conducted under the right conditions. A norm is valid if it could meet with the agreement of all affected as participants in an argument free from coercion, open to all relevant considerations, and oriented toward mutual understanding rather than strategic advantage. The ideal speech situation, the conditions under which such discourse could function properly, serves as a regulative ideal against which actual discourses can be evaluated.

This is very elegant work. It avoids the metaphysical extravagance of older moral realism while still making moral validity more than a matter of personal preference, and takes seriously that moral questions are questions we have to answer together, not privately. It provides us a basis for critique of actual discourses that fall short of the ideal. I have real admiration for what Habermas built here, and I want to say that clearly before explaining why I think it does not go far enough.

A Notable Convergence

Modal Path Ethics and Habermas's framework still converge in their diagnoses more than in their positive proposals. Both of us see contemporary moral discourse as systematically distorted, think the distortion operates at the level of structures and systems rather than individual failings, and hold that serious moral philosophy has to include a diagnostic dimension: an account of why moral thinking so regularly goes wrong, not just a proposal for how to do it right.

The distortion field concept in Modal Path Ethics is closer to Habermas's analysis of systematically distorted communication than any other influence I can personally name. When I write about how perception within a distorted field becomes bent away from structural contact with harm, or describe how participants in such fields sincerely believe they are engaged in honest reasoning while the conditions for such reasoning have been undermined, I am clearly working in territory Habermas mapped out for me before I got there. I do not think I borrowed the framework directly, but I do think we both arrived at similar observations because the phenomenon is real and visible from multiple philosophical starting points. But his articulation is definitely sharper in many respects than mine, and I want to acknowledge that.

His analysis of instrumental reason colonizing regions of life that require communicative rationality is also something I find useful. When Modal Path Ethics writes about how institutions come to preserve their own operational continuity while degrading the conditions under which ordinary loci can continue non-harmfully, I am describing something I think Habermas would recognize as a version of his lifeworld colonization story. The mechanisms I identify are not exactly his, but the phenomenon is adjacent.

So the first thing to clarify is that Habermas has genuine diagnostic power. Readers who want to understand what goes wrong in contemporary moral and political life have a lot to learn from him, and I am not trying to displace that work.

Where I Still Think He Goes Wrong

What I want to argue with is not the diagnostic work but the grounding claim.

Habermas holds that moral validity is constitutively tied to the conditions of justification in practical discourse. A norm is valid if it could be justified to all affected as participants in argument conducted properly. There is no moral fact that exists independently of the conditions of possible justification.

I do not believe this.

Consider the sterilizing gamma-ray burst that forecloses the possible emergence of life on a once-promising world. On Habermas's account, I have absolutely no resources to call this a harm. There are no participants in any possible discourse who could be affected by the event in the relevant sense, no community of rational agents whose agreement could be sought or withheld, no conditions of justification that could obtain. If moral validity requires possible justification among rational participants, then events that occur outside any possible discursive community cannot be morally evaluated at all.

But that cannot be right. The foreclosure of possible life on a once-promising world is still morally significant. A world where that happened is worse off than a world where it did not. The significance does not depend on whether any rational community could justify the event to itself; it depends on what actually happens to the reachable future of that world.

Habermas would probably say I am smuggling in a metaphysical realism that cannot be defended once the linguistic turn is taken seriously. And I would say that the linguistic turn, for all its real contributions, produced a philosophical tradition that systematically cannot see certain kinds of moral facts because its starting point simply excludes them by construction. The move from the philosophy of consciousness to the philosophy of language was supposed to be a liberation, and in many respects it was.

But one thing it took with it, more or less permanently in the post-Habermasian tradition, was the capacity to recognize moral facts that obtain outside any possible discursive community. This is not a small loss. The range of such facts is not marginal. It includes:

Harms to future beings whose existence depends on present choices that they cannot participate in.

Harms to non-human beings whose moral standing cannot be grounded in their participation in any communicative community.

Harms distributed across populations systematically excluded from discourse by the very structures being evaluated.

Harms to ecological systems whose continuation is morally significant in ways that no current discourse tracks adequately.

Pre-life harms at the level of planets, biospheres, and physical conditions that precede the emergence of any communicative community at all.

Each of these categories represents moral facts that matter, and none of them can be handled natively by a framework that grounds validity in possible discourse. Habermasian theorists have attempted various accommodations for some of these, particularly for future generations and for non-human beings, but the accommodations always have the character of extensions or analogies rather than native cases. The framework is built for intersubjective disputes among rational agents, and everything else has to be fit in afterward, with varying degrees of success.

The Stakes Are Very Real

What I am arguing against is not Habermas's specific articulation but the deeper assumption his framework shares with most of post-Kantian moral philosophy: that the central cases of moral reality are cases of intersubjective dispute between rational agents, and that anything else is peripheral.

I do not think this is true. The central cases of moral reality, on my view, include the full range of structural harms that obtain regardless of whether any discursive community can recognize them. A framework adequate to these cases has to be built differently than a framework adequate primarily to intersubjective dispute.

Modal Path Ethics is my attempt at such a framework. It grounds moral validity in structural facts about extance rather than in conditions of justification. It can recognize pre-life harm, ecological harm, and harm to excluded populations natively rather than through extension. It handles intersubjective dispute as a special case within a broader structural analysis rather than treating it as the paradigm from which everything else must be derived.

This does not make my framework better than Habermas's framework for every purpose. For intersubjective disputes among rational participants, especially in political contexts where discursive legitimacy is a genuine concern, his framework probably does better than mine. The discourse ethics tradition has developed resources for thinking about democratic deliberation, institutional legitimacy, and the normative structure of public reasoning that Modal Path Ethics does not replicate and would be foolish to try to replace.

What I am claiming is that his framework is not adequate as a complete account of moral validity, because it excludes by construction moral facts that exist and matter. A more complete philosophical position would include both a discourse-ethical analysis for the cases where it works and a structural analysis for the cases where it does not.

Let me close with something closer to honesty than academic positioning. I spent some time reading Habermas during the writing of this book. The reading was useful even where I ended up disagreeing, and probably especially where I ended up disagreeing, because working out where I disagreed and why forced me to articulate in prose positions I might otherwise have left vague.

There is a temptation in this kind of essay to present the disagreement as cleaner than it actually is, or to make it sound like I always knew what I thought and Habermas was simply wrong in the ways my framework is right, which would be dishonest. What actually happened was more like I read Habermas, I found much of it compelling, I historically tried to work within the broadly discourse-ethical orientation, I kept running into cases that the framework could not handle natively, and later on I concluded that the cases I was trying to handle were the ones that matter most and that the framework I wanted to build had to be constructed differently.

Habermas made this conclusion harder, which is what a good philosopher does for those working in adjacent territory. The frameworks disagree, but the disagreement is productive rather than dismissive, and I want to be clear that my disagreement is with his conclusions rather than with his seriousness or his contribution.
