STRONG POLITICAL LIBERALISM
(Accepted 27 October 2023)
ABSTRACT. Public reason liberalism demands that political decisions be publicly
justified to the citizens who are subjected to them. Much recent literature
emphasises the differences between the two main interpretations of this requirement, justificatory and political liberalism. In this paper, I show that both views
share structural democratic deficits. They fail to guarantee political autonomy, the
expressive quality of law, and the justification to citizens, because they allow
collective decisions made by incompletely theorised agreements. I argue that the
result can only be avoided by changing public reason’s role in collective decisionmaking. Instead of incompletely theorised agreements, we should demand
agreement both on the public reasons themselves and on the other premises that
justify political decisions. In this way, it is always possible to point to a procedureindependent reason that justifies democratic decisions, and the reasoning of the
state is public and contestable. Finally, I explain how this, in turn, implies that only
political liberalism can be rescued—by accepting what I will call strong political
liberalism. Modifying justificatory liberalism in the necessary way will inevitably
open the door to an objectionable form of perfectionism.
In many liberal democracies, anti-discrimination rules do not apply
to the employment of religious leaders. Christian churches, Muslim
mosques, and Jewish synagogues are legally allowed to hire only
male priests, imams, and rabbis. It is often thought that this so-called
‘ministerial exception’ follows from a commitment to freedom of
religion. Moreover, it is said that this is a public reason, a reason that
in some important sense is accessible to every reasonable citizen.1
However, there are also reasons available for thinking that the
ministerial exception is wrong. For example, one such reason is that
the exception could be said to communicate that women are inferior
to men. Another is that the exception could be seen to be discrim1

inatory in an objectionable way—it violates women’s robust freedom of occupational choice. Women who want to be priests, imams,
or rabbis are denied this opportunity. These reasons, too, are commonly thought to be accessible to every reasonable citizen, and so
they are typically also seen as public.
It is a central feature of one of the most widely accepted views of
liberal legitimacy, political liberalism, that political decisions must be
justified with public reasons of this kind. Up until now, it has always
been assumed that it is permissible to appeal to an indeterminate
plurality of public reasons when justifying political decisions. In
other words, decisions do not need to be justified by one public
reason, or a clear ranking of public reasons. If a parliamentary
majority wants to revoke the ministerial exception, and disagree
about why that is, this is perfectly acceptable, as long as the reasons
they rely on are public. One group can say that it communicates
women’s inferiority, another that it violates robust freedom of
occupational choice. It is enough that they accept the conclusion. A
decision can be reached by way of an incompletely theorised agreement.
Political liberalism belongs to a family of views of liberal legitimacy that is sometimes called public reason liberalism. Much recent
work has focused on the differences between political liberalism and
the main alternative in this family, justificatory liberalism.2 However,
both family members share an important similarity: they allow
incompletely theorised agreements. Yet, whereas political liberalism
puts restrictions on the reasons legislators might have for accepting
the agreement, justificatory liberals say that there is nothing precluding an agreement based entirely on non-public reasons.

STRONG POLITICAL LIBERALISM
In this paper, I argue that incompletely theorised agreements
cause significant problems for liberal views of legitimacy. They
undermine political autonomy, lead to an erosion of the expressive
quality of laws and fail to ensure justification to citizens. These
problems are present for both political liberalism standardly understood and for justificatory liberalism.3
I then demonstrate that political liberalism can overcome these
problems. What I will call strong political liberalism, a view according
to which there needs to be a majority agreement on the reasons
justifying a decision, is a plausible and attractive alternative that does
so. An upshot of my analysis is that justificatory liberalism cannot be
salvaged without opening the door for an objectionable form of
perfectionism.
I make three main interventions. First, I argue that there is an
intimate relationship between the decision-procedure we adopt,
political autonomy, the expressive power of law, and justification to
citizens. Second, I show how this entails that we must choose between committing to the standard interpretations of political liberalism and justificatory liberalism and upholding these ideals. I argue
that we should opt for the latter, while changing our understanding
of public reason’s role in collective decision-making. Instead of
incompletely theorised agreements, we should demand agreement
both on the public reasons themselves and on the other premises
that justify a decision. (...truncated)
