We all agree that democratic decision-making requires a factual input, and most of us assume that when the pertinent facts are not in plain view they should be furnished by well-functioning scientific institutions. But how should liberal democracy respond when apparently sincere, rational and well-informed citizens object to coercive legislation because it is based on what they consider a misguided trust in certain parts of science? Cases are familiar, the most prominent concerning climate science and evolution, but one may also (...) count GMO-skepticism and vaccine-skepticism, and there are plenty of others. The paper defends what I, borrowing an expression from Badiola, call Science as Public Reason, asserting roughly that some policy-relevant factual proposition P is part of public reason if and only if there is consensus about P among scientific experts in the relevant well-functioning scientific institutions. I defend this view against the controversiality objection claiming that scientific findings cannot in this general way pass as public reason as they are sometimes controversial among reasonable citizens. My preferred line of defense is what I call Dogmatism about Science as Public Reason, which roughly amounts to insisting on Science as Public Reason on the ground that it is a philosophically well-motivated view, while conceding that it may not be acceptable to all minimally rational and well-informed individuals.

Some moral value is transparent just in case an agent with average mental capacities can feasibly come to know whether some entity does, or does not, possess that value. In this paper, I consider whether legitimacy—that is, the property of exercises of political power to be permissible—is transparent. Implicit in much theorising about legitimacy is the idea that it is. I will offer two counter-arguments. First, injustice can defeat legitimacy, and injustice can be intransparent. Second, legitimacy can play a critical (...) function in our practical thought, which sometimes requires intransparency. (shrink)

Mainstream political liberals hold that state coercion is legitimate only if it is justified on the grounds of reasons that all may reasonably be expected to accept. Critics argue that this public justification principle is self-defeating, because it depends on moral justifications that not all may reasonably be expected to accept. To rebut the self-defeat objection, I elaborate on the following disjunction: one either agrees or disagrees that it is wrong to impose one’s morality on others by the coercive power (...) of the state. Those who disagree reject PJP, they understand politics as war. Those who agree accept PJP, they understand politics as competition. Political competitors abide by PJP to avoid politics as war, by enforcing PJP on political combatants they engage in a war that is unavoidable. In both cases their exercise of political power has a justification that is reasonably acceptable to all. (shrink)

According to John Rawls’s famous Liberal Principle of Legitimacy, the exercise of political power is legitimate only if it is justifiable to all citizens. The currently dominant interpretation of what is justifiable to persons in this sense is an internalist one. On this view, what is justifiable to persons depends on their beliefs and commitments. In this paper I challenge this reading of Rawls’s principle, and instead suggest that it is most plausibly interpreted in externalist terms. On this alternative view, (...) what is justifiable to persons is not in any way dependent on, or relativized to, their beliefs and commitments. Instead, what is justifiable to all in the relevant sense is what all could accept as free and equal. I defend this reinterpretation of the view by showing how it is supported by Rawls’s account of the freedom and equality of persons. In addition, a considerable advantage of this suggestion is that it allows for an inclusive account of to whom the exercise of political power must be made justifiable. (shrink)
