The status of scientific knowledge in political liberalism is controversial. Although Rawls argued that the noncontroversial methods and conclusions of science belong to the kind of reasons that citizens can legitimately call forth in public deliberation, critics have observed that the complexity and elaborateness of scientific arguments drive them away from the spirit of public reason, i.e., that which should reflect judgments that are the product of general beliefs and forms of reasoning found in common sense. In other words, scientific (...) claims remain as inaccessible as esoteric or religious reasons. This paper contends that this objection can be met by introducing a crucial assumption, drawn from W. V. O. Quine and the ‘naturalized epistemology’ tradition: that scientific reasoning and everyday reasoning are not two different epistemic categories but rather form a continuum. The former is just a filtered or refined version of the latter. Accordingly, evidence-based scientific reasoning is common to all citizens, regardless of their actual acceptance of specific scientific claims. Following the Quinean Assumption, political liberals may argue that, unlike religious or esoteric sources of knowledge, scientific reasoning is the expression of a cognitive operation that is fundamentally shared across comprehensive doctrines and politically reasonable individuals.

Suppose we have a persistent disagreement about a particular set of policy options, not because of an underlying moral disagreement, or a mere conflict of interest, but rather because we disagree about a crucial non-normative factual assumption underlying the justification of the policy choices. The main question in the paper is what political legitimacy requires in such cases, or indeed whether there are defensible answers to that question. The problem of political legitimacy in fact-dependent policy disagreements has received almost no (...) attention in political philosophy, which has focused mostly on value disagreements and proposed theories of legitimate coercive legislation in valuedependent disagreements. The paper presents an argument showing that under certain plausible assumptions regarding legitimacy, there are serious difficulties in identifying legitimate choices in fact-dependent policy disagreements. This may be unsurprising to political philosophers preoccupied with value-based disagreements, perhaps because it has been assumed that legitimacy-related concerns are irrelevant to fact-dependent policy disagreements. The paper argues that this response is premature. If we should care about legitimacy et al.l, then it is by no means clear why we should ignore issues of legitimacy in policy-disputes that depend on factual disagreements. The paper ends by defining a set of possibilities that merit further exploration in search of a theory of legitimacy in fact-dependent policy disagreements. (shrink)

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.

After the demise of Christianity, Western society did not become secular, according to Emile Durkheim, but located foundations in a new religion he calls the “cult of the individual.” This religion holds the rational individual person as sacred, and corresponds to a multi-faceted, complex, and diverse society united around individual democratic rights and modern science. Different traditional religions can co-exist in the cult of the individual, but only if they accept a subordinate status in relation to it. Durkheim maintains, however, (...) that all religions construct authoritative regimes of truth and moral obligations, setting the stage for conflict. How then should modern democracies respond to challenges to their authority from traditional religions? This article argues that a Durkheimian response would be to assert the values of the cult of the individual, as this is the only way to maintain the integrity and viability of Western democratic society.

According to John Rawls, the methods and conclusions of science—when these are non-controversial—constitute public reasons. However, several objections have been raised against this view. This paper focuses on two objections. On the one hand, the associational objection states that scientific reasons are the reasons of the scientific community, and thus paradigmatically non-public in the Rawlsian sense. On the other hand, the controversiality objection states that the non-controversiality requirement rules out their public character when scientific postulates are resisted by a significant (...) portion of the citizenry. The paper replies that both objections miss their mark. To the associational objection, it replies that the relevant test for a reason to be public is whether the reasons have been construed under the rules and constrains of a public frame of thought. Insofar as scientific methods and conclusions correspond to the principles of reasoning and rules of evidence that liberals understand as public, their associational origin is secondary. To the controversiality objection, it replies that the standard for a scientific argument to be regarded as non-controversial should refer to its degree of intra-scientific consensus, since ordinary citizens accept or reject scientific pronouncements conditioned to their particular comprehensive views. Nonetheless, a wide extra-scientific agreement on the epistemic virtues of the scientific method will be needed. The paper concludes that there is a good case to think about scientific reasons as public to the extent that scientific reasoning is a mode of inquiry that mirrors a central aspiration of Rawlsian political liberalism: having a public way of thought and an impersonal standpoint to adjudicate between competing claims.

ABSTRACTIn his account of public reason Rawls assumes that some facts ought to be treated as ‘fixed’, or beyond reasonable disagreement. These include, for him, facts upon which there is a scientif...

Most debates surrounding the teaching of creationism in the science classroom have been addressed under a standard frame: whether creationism is science or religion. As creationism suggests supernatural causation, it has been understood as beyond the purview of science, and therefore as religion. This argument for methodological naturalism has been increasingly challenged by philosophers of science as a demarcation criterion. The disaggregation approach introduced by Cecile Laborde provides an alternative framework to address this debate. It suggests that the problem with (...) creationism lies in its epistemic inaccessibility, as it is a theory with weak explanatory capacity that has been superseded by Darwinian evolution. Thus, the exclusion of creationism from the science classroom is not grounded in its religious character, but rather in a set of epistemic shortcomings, which are shared by other fully secular pseudoscientific theories. In the same way that religion is not special as a legal-political category under Laborde’s analysis, creationism in the curriculum should not be treated as special either. (shrink)

In “Justice as Fairness: Political not Metaphysical,” John Rawls suggests an approach to a public conception of justice that eschews any dependence on metaphysical conceptions of justice in favor of a political conception of justice. This means that if there is a metaphysical conception of justice that actually obtains, then Rawls’ theory would not be sensitive to it. Rawls himself admitted in Political Liberalism that “the political conception does without the truth.” Similarly, in Law of Peoples, Rawls endorses a political (...) conception of justice to govern the society of peoples that is not concerned with truth, but instead concerned with being sufficiently neutral so as to avoid conflict with any reasonable comprehensive doctrines. The odd result is that this neutrality excludes any conception of truth at all. Therefore, in times of crisis that demand incisive decision making based on scientific, economic or moral considerations, public reason will stall because it can contain no coherent conception of truth.

Public reason liberals disagree about the relationship between public justification and deliberative democracy. My goal is to argue against the recent suggestion that public reason liberals seek a ‘divorce’ from deliberative democracy. Defending this thesis will involve discussing the benefits of deliberation for public justification as well as revisiting public reason’s standard Rawlisan restraint requirement. I criticize Kevin Vallier’s alternative convergence-based principle of restraint and respond to the worry that the standard Rawlsian restraint requirement reduces the likelihood of public justification (...) by limiting the diversity of inputs into the justificatory process.
