Habermas: Religion in the Public Sphere – 27/06/2016


A Pluralist Democracy

Here are two assumptions we’ll accept for the sake of argument:

  1. We live in a democracy (or in a state that strives to be a democracy, or at least pretends to be one, however much of a mess they make of it in practice).
  2. The citizenry of that democracy is characterised by religious plurality: various religious and non-religious worldviews and ways of life co-exist, and (importantly) this is likely to remain this way.

Democracies occur in many forms, historically, but all have in common that they ought to be an expression of the Democratic Principle: those who are subject to the law, should be able to view themselves as co-authors of that law.

Of course, the way in which citizens can contribute to law-making can take many forms: electing representatives, voting in a referendum, starting and signing petitions, but also contributing to public debate through open, public forums, which require some basic democratic rights, such as freedom of press, freedom of expression, the right to a defense in court and the right to education (this is not an exclusive list).

An often-made mistake is to equate democracy with simple majoritarianism. Majoritarianism is ‘doing what the majority wants’, which can easily be established by a vote. This system is certainly a useful decision making tool, and can at times be applied in a democracy, but it is not the same as a democracy, since it can run against the Democratic Principle. The problem with majoritarianism is that it can lead to what is known as ‘the tyranny of the majority’. A majority can vote to unjustly oppress a minority, so in a majoritarian system, minority rights are in danger. A majority vote in favour of prosecuting homosexuals is a case in point. The problem with this is that the homosexuals in question would be subject to that decision, but they can hardly view themselves as co-authors of it. A democracy requires that all those who are subject to binding decisions should be able to have access to a justification they could come to accept as reasonable, and they should be able to influence that decision by offering a justification of their own. In short: in a democracy citizens owe one another reasons for laws, a vote alone won’t do.

A democracy, therefore, consists of a wide variety of social rights and institutions. We live in a democracy all the time, not only on election day.

Religion in the Public Sphere

So in a democracy, the public sphere is one of these important institutions. German philosopher Jürgen Habermas has written a lot about the public sphere, ever since the seventies. The public sphere is the domain in which citizens of a democracy discuss matters of public concern with each other. This can be online and offline, in the media, in the pub, in the bus, in the classroom. Habermas divides the public sphere in two tiers: the informal public sphere and the formal, political public sphere. The informal public sphere is the domain where ordinary citizens discuss matters of public concern, and the political public sphere is the domain where policy makers and other public official formulate and finalise laws: parliament and the court of law are examples.

Democratic deliberation takes place in these two tiers of the public sphere. Citizens contribute justifications to the informal public sphere that public officials pick up, and public officials justify the laws they make in the formal public sphere.

In the past two decades, the following question has been a topic of hot debate:

In a democracy, can religious justifications count as legitimate justifications for laws, or should laws be supported by secular reasons only?

One of the basic rights essential for a democracy is freedom of religion. Freedom of religion consists of a negative and a positive freedom. The negative freedom entails the right to be free from the religion of others, so others are prevented from imposing their religion on you, even if that were the religion of the majority. The positive freedom entails the right to exercise one’s religion as one sees fit, which enables you to build churches and temples, dress in certain ways or observe certain diets or celebrate certain religious holidays. Each society can negotiate these two freedoms in various ways, but what is important is that both are respected. Habermas explicitly states that he is committed to both the negative and the positive freedom of religion.

So, at face value, this poses a problem. On the one hand, the positive freedom of religion protects the freedom of religion citizens to use their religious views in the public sphere, including in discussions about laws that apply to all. On the other hand, the negative freedom of religion protects the non-religious citizens, or citizens who adhere to minority religions, from having the religion of others imposed on them, which might happen if a law is supported solely with a religious justification. How to solve this problem?

American philosopher John Rawls suggests that citizens can use religious reasons in discussions in the public sphere, but “in due course”, when the law is finally made, the law should be supported by sufficient “public reason”. By “public reason”, Rawls means reasons that every reasonable citizen could reasonably come to accept. For instance, when a religious citizen goes to the polling station, they ought to be able to justify their vote with sufficient reason, even if their own reasons for casting that vote is religiously motivated.

Another philosopher, Nicholas Wolterstorff, however, argues that what Rawls demands of religious citizens is (a) too demanding, and (b) goes against the positive freedom of religion. He argues that many religious citizens are unable to make a “split” in their reasoning between religious and secular reasons, without having to be disingenuous or threatening their own integrity. It is, as it were, part and parcel of their religious commitment that they base their political actions on those religious views. This objection of Wolterstorff against Rawls is called the Integrity Objection. This threat to the internal integrity of religious citizens is particularly a problem because that burden is not asked of non-religious citizens, which poses an unjustified unfairness.

Habermas takes Wolterstorff’s objection seriously and has an alternative to Rawls: he calls it the translation proviso: citizens can use religious justifications for laws in the informal public sphere, even without offering additional secular reasons in support of their proposal. However, in the formal, political public sphere, officials must use secular justifications alone to justify the laws they make. To avoid simply ignoring the religious contributions to public debate, it is essential that religious reasons be translated to secular reasons. This job of translation, according to Habermas, is a responsibility religious and non-religious citizens carry together, as a co-operative task. This means that both religious and non-religious citizens must engage in a mutual learning process: religious citizens must learn to accept that their religious doctrines don’t have a privileged appeal to truth, and that there are rivaling religious and secular doctrines that deserve to be treated with equal respect. Non-religious citizens must learn that religious worldviews are not simply relics of an archaic past, bound to disappear, but that instead religious reasons are vehicles of relevant content that can shine new light on issues of public concern. In the process of translation, Habermas believes that this relevant content can be distilled from religious justifications and reformulated in secular terms.

For Habermas. Secular language differs from religious language in that it is “equally acceptable to all”, whereas religious language is only accessible to those who already adhere to that religion. That is the reason why, in Habermas’ view, at the end of the day, only secular reasons are able to meet the requirements of the democratic principle. His translation proviso, he argues, thus protects both the negative and the positive parts of the freedom of religion.

Martha Nussbaum – The Capability Approach 06/06/16

Contemporary debates about the philosophy of social justice face challenges that are particular to our times. Martha Nussbaum developed – based on the capabilities-based development theory of Indian economist Amartya Sen – a sophisticated answer to many of these challenges, which she outlines in her book Creating Capabilities (2011). What are these contemporary challenges, and how does Nussbaum attempt to meet those challenges?

Contemporary challenges

Global justice. It is uncontroversial that resources and opportunities are unfairly distributed. Not only within countries or states, but also among states. Some states have more resources, or are better able to manage their resources, than others. What do richer states morally owe poorer states? On the one hand, the inequalities between states are arbitrary and not the result of a fair process, so fairness requires that these inequalities be compensated, particularly since these inequalities currently lead to dehumanizing conditions for many. On the other hand, really equal distribution of resources across states is as good as impossible to govern.

Imperialism. We’d like to think that the times when Western nations went around the world invading territories, claiming land and resources for themselves and imposing their laws, norms, religions, languages, culture and governance upon other peoples is long behind us. Likewise, we’d like to think that women and men enjoy equality in all spheres of life and that battles like that of the suffragettes is a thing of the past. But reality is uncomfortable in this respect. Feminists and anti-colonialists have often persuasively pointed out that even after decolonisation and the legal recognition of equality for man and women, male and Western norms are still culturally dominant, often in hidden and implicit ways. Feminist philosophers have argued that many moral and political philosophies in the history of philosophy implicitly assume male standards that don’t quite fit women’s experiences. Likewise, Western philosophies have been shown to implicitly assume a European or US American context, thereby discounting non-Western societies from the outset, but at the same time claiming universal applicability. Western philosophies thus are in danger of implicitly making imperialist claims without realizing it. In this light, postmodern concerns – like those put forward by Nietzsche – spring to mind: is it at all possible to formulate a moral or political theory that has universal application, or does such a theory always amount to imperialism, whereby the dominant group imposes its arbitrary morality on everyone? But if a theory of justice has no universal applicability, can it be said to be a theory of justice at all? After all, aren’t we all owed the same respect, in virtue of our humanity?

Justice to animals. Can justice apply to non-human animals, too? Few would argue that animals can make the same moral claims as humans, or that they should have the same rights. But equally few would claim they are not owed any moral respect at all. Presumably, truth lies somewhere in between. Animals are sentient, they can feel pain and pleasure, fear and joy. Many people would argue that animals should be protected from pointless cruelty. But which criteria apply here? A theory of justice that is not at all able to consider or apply to non-human animals is, these days, considered to have a serious handicap.

The Capability Approach

Martha Nussbaum can’t be said to lack ambition. She claims that her theory of social justice meets all three of the above challenges. She starts from the Aristotelian idea that the idea of justice ought to be based on the question: “What is each person able to do and to be?”[1] If we are to judge any society on its basic justice or decency, that’s the question we should ask, according to Nussbaum. To further break this question down, she has formulated ten capabilities, which form the basis of her account of justice. These ten capabilities are:

  1. Life.
  2. Bodily health (“including reproductive health”)
  3. Bodily integrity (including “opportunities for sexual satisfaction and for choice in matters of reproduction”)
  4. Senses, imagination, and thought (“being able to use the senses, to imagine, to think, and to reason”)
  5. Emotions (“being able to have attachments to things and people outside of ourselves”)
  6. Practical reason (“being able to form a conception of the good”)
  7. Affiliation (“being able to live with and toward others”)
  8. Other species (“being able to live with concern for and in relation to animals, plants, and the world of nature”)
  9. Play (“being able to laugh, to play, to enjoy recreational activities”)
  10. Control over one’s environment (“being able to participate effectively in political choices” and “being able to hold property and having property rights”) [2]

These ten capabilities constitute Nussbaum’s account of social justice. To understand how they work, however, a few further things must be said about these capabilities.

Firstly, these ten capabilities form the basis of justice. Justice should be understood in these terms; they are not mere symptoms of justice.

Secondly, these ten capabilities are universal. They apply to all humans and even to non-human animals, regardless of culture of context.

Thirdly, having these capabilities, does not mean that one also enacts them. This should be a matter of free choice, according to Nussbaum. She therefore distinguishes ‘functioning’ from ‘capabilities’, whereby functioning refers to doing what a capability enables one to do. For instance, I may have the capability to connect with other species – I am able to do so and no one is hindering me from doing so nor coercing me to do so – but whether I actually choose to do so is a different matter. The capability approach is therefore a distinctly liberal approach.

Fourthly, Nussbaum employs a threshold with regard to these capabilities. That means that in order for a person to live a life of dignity, and for a society to deserve the label ‘decent’ or ‘minimally just’, these ten capabilities must be enabled to a certain, minimal, degree. It is hardly intelligible that a person could exercise them to a maximum degree, since contingent circumstances necessarily limit them. Hence, justice does not require that people are unlimited in the exercise of these capabilities, but that they have them to a certain degree.

Fifthly, the ten capabilities relate to each other. If the conditions for reasonable bodily health and longevity aren’t met, for instance, we also won’t be capable of many other things. A society is therefore just only if for each citizen conditions are provided that practically enable all ten capabilities to threshold level. That also means that the lack of one capability can not be compensated with an excess in another capability. No amount of education can compensate for the lack of bodily health. All capabilities must be met to threshold level.

Does Nussbaum’s account meet the three contemporary challenges?

According to Nussbaum, societies that are unable to reach a minimum threshold level of these ten capabilities for their members ought to receive help from societies that do have the resources and institutions to provide these ten capabilities. This is, according to Nussbaum, a reasonable demand for global justice.

Although Nussbaum claims that her approach has universal applicability, she is sensitive to the dangers of imperialism. However, she has thought of this too. The capabilities are sufficiently generic, according to Nussbaum, to allow for significant differences in cultural interpretation. How or to which extent we choose to play, make decisions about our bodies or relate to the other species can be informed in various ways by our religion, culture, upbringing, ethical views, tastes or environment.

Finally, the ten capabilities can be employed to evaluate not only the level of justice towards humans, but also non-human animal species. Perhaps even robots!



Thanks for reading my introduction, but who can really explain it better than Martha Nussbaum herself? I really recommend watching this lecture. It is very clear and detailed and really brings home why Nussbaum thinks all of this is very, very important.

Hobbes’ Political Philosophy – 09/05/2016

Thomas Hobbes (1588-1679) grew up in turbulent times, which culminated in the English Civil War. Civil wars are a right mess. They tend to be perfect opportunities for mankind to show its dark and ugly side. It should therefore not come as a surprise that Hobbes was a cynic about human nature. He believed that humans are naturally motivated by self-interest and will use the power they have to serve their own interests, even at the cost of others. How could peace be possible among such a-moral beings? This is Hobbes’ biggest philosophical question, one he attempts to answer in Leviathan, which is considered one of the most rigorous and influential philosophical works in the history of Western philosophy.

The State of Nature

Hobbes invites us to imagine that we all live together without a government. In such a condition, he believed, we would have to be afraid of everyone else. Resources are scarce and everyone is after them. Therefore, it would be rational to use violence in order to get to those resources first. But since everyone can be expected to use such violence, it is also rational to not trust anyone and use violence against them to prevent them from using violence against you. We would be in permanent danger, permanently afraid. Hobbes believed there is no natural hierarchy that might establish a sustainable natural order. Everyone has some power to pursue their interests, but even the most powerful are vulnerable when they sleep, and even the weakest cannot be fully dominated, because they might revolt at the first opportunity. In this situation it would be impossible to cooperate, which is necessary to produce the resources to meet everyone’s interests. We would be unable to cultivate land or invent or manufacture anything, because for such enterprises we need peace and trust. We’d just be too busy defending ourselves by killing each other. The State of Nature, according to Hobbes, is a state of war, and life in the State of Nature is “solitary, poor, nasty, brutish and short”.

The Laws of Nature

Hobbes thinks humans are self-interested and motivated by a fear of death, but luckily they are also rational. This means they can understand the Laws of Nature. The Laws of Nature include the idea that one should treat another the way one wants to be treated. Human nature is perhaps selfish, but not cruel. Humans are naturally inclined to cooperate and treat each other with respect, because eventually that serves their best interest. The thing is, that in the State of Nature, they are unable to live according to the Laws of Nature because they are forced to defend themselves with violence. The State of Nature is therefore against human nature and also against the Laws of Nature, according to Hobbes. Since humans are rational, they are able to see that it is in their own and everyone else’s best interest to avoid the State of Nature at all cost.

The Social Contract

Since humans share the insight that they should avoid the State of Nature, they can see that it is rational to surrender some of their freedom in exchange for stability, security and peace. They see that it is rational to establish a political authority: a state. Since this in Hobbes’ philosophy it is seen as an implicit agreement to establish a political authority, this justification takes the form of a Social Contract. Hobbesian subjects enter a covenant with each other, based on their own rationality. This idea of a Social Contract is later used by many other political philosophers, including Locke and Rousseau, but also Rawls, more recently.

The Sovereign

What kind of government would Hobbesian subjects agree to? For Hobbes, the only rational option is an autocracy: a sovereign with absolute political authority to establish the law and the power to ensure that the law is upheld. Political legitimacy is derived from the efficiency of the sovereign to establish and sustain peace and stability. It doesn’t matter how the sovereign came to power – by force, conquer, election or flipping a coin – as long as there is a sovereign and the sovereign can guarantee peace. Hobbes also doesn’t really care whether the sovereign is just or respectful towards its subjects. Subjects should tolerate poor governance because the alternative – the state of nature – is nearly always worse. As long as there is stability, humans have the security to cooperate, develop moral behaviour and start other valuable endeavours that would be impossible in the State of Nature.

For the same reason Hobbes is strongly anti-democratic. As soon as political power is divided among different parties or distributed among the subjects, there will be scope for strife for power. With that you get suspicion and fear and before you know it, you’re on a slippery slope toward the State of Nature again. Since the State of Nature was what we were trying to avoid in the first place, democracy is not a rational form of governance, according to Hobbes. This conclusion makes Hobbes a controversial thinker. In his defense, however, he couldn’t have known about the tyrants of the 20th century that made us so suspicious of autocracy.

Plato’s Cave, and CAKE! – 04/01/2016

platos caveDo the thoughtless comments people make about matters of justice leave you feeling hopeless? Are you frustrated by party politics when those who should be ruling the country in fact care more about their own power? If you answer ‘yes’ to these questions, you might be sympathetic to what Plato is trying to convey in his most famous book, The Republic.

But, as with all meaningful philosophy, Plato’s view is controversial. Plato is vehemently anti-democratic…

The first West London Philosophy School class on Monday the 4th of January 2016 will be about Plato’s Allegory of the Cave. It is the most famous allegory in the history of philosophy, which appears in the dialogue between Socrates and Glaucon in book VII of The Republic. In the dialogue, Socrates and Glaucon are discussing the question: what is justice? But along with that question, Plato – through the character of Socrates – tries to teach us something about education and insight: how do we learn the truth?

To celebrate the opening of the West London Philosophy School, cake will be served during the break!

Plato’s Cave 2007 by Ken Stout


An old but good translation of Book VII of the Republic is Paul Shorey’s (1935-1937). You can find it here.

Tim Wilson made this wonderful animated mini lecture on Plato’s Cave.
