This article argues for the elimination of the concept of life worth living from philosophical vocabulary on three complementary grounds. First, the basic components of this concept suffer from multiple ambiguities, which hamper attempts to ground informative evaluative and classificatory judgments about the worth of life. Second, the criteria proposed to track the extension of the concept of life worth living rest on unsupported axiological assumptions and fail to identify precise and plausible referents for this concept. And third, the concept of life worth living is not shown to serve any major evaluative or classificatory purpose besides those served by already available axiological concepts. By eliminating the concept of life worth living, philosophers will free themselves of the task of addressing ill-posed axiological questions and ground reflection about the worth of life on more rigorous conceptual foundations.

This paper articulates and defends a novel type of precautionary argument for situations of severe uncertainty in science and policy, which I term precautionary slippery slope argument. The paper explicates the structure of precautionary slippery slope arguments, identifies the main factors that bear on the strength of these arguments, and illustrates how the proponents of such arguments can address several influential objections put forward against standard slippery slope arguments and other prominent forms of precautionary reasoning.

This article articulates and defends a dissolution of the so-called repugnant conclusion, which focuses on the notion of life worth living figuring both in Parfit's formulation of the repugnant conclusion and in most responses to such a conclusion. The proposed dissolution demonstrates that the notion of life worth living is plagued by multiple ambiguities and that these ambiguities, in turn, hamper meaningful debate about both the issue of whether the repugnant conclusion can be avoided and the issue of whether the repugnant conclusion is actually repugnant. This result does not exclude that some modified versions of the repugnant conclusion may yield valuable insights about the value of populations and the tenability of different axiological/ethical theories. Still, if the proposed dissolution is correct, then the repugnant conclusion rests on an ill-defined notion and we lack the information required to assess the merits of the repugnant conclusion.

This article defends informed preference satisfaction theories of welfare against the most influential objections put forward in the economic and philosophy of science literatures. The article explicates and addresses in turn: the objection from inner rational agents; the objection from unfeasible preference reconstruction; the objection from dubious normative commitments; the objection from conceptual ambiguity; and the objection from conceptual replacement. My defence does not exclude that preference satisfaction theories of welfare face significant conceptual and practical challenges. Still, if correct, it demonstrates that philosophers/welfare economists are justified in relying on specific versions of such theories, namely informed preference satisfaction theories.

This paper provides a philosophical assessment of leading theory-based, evidence-based and coherentist approaches to the definition and the measurement of wellbeing. It then builds on this assessment to articulate a reformed division of labor for the science of well-being and argues that this reformed division of labor can improve on the proffered approaches by combining the most plausible tenets of theory-based approaches with the most plausible tenets of coherentist approaches. This result does not per se exclude the possibility that theory-based and coherentist approaches may be independently improved or amended in the years to come. Still, together with the challenges that affect these approaches, it strengthens the case for combining the most plausible tenets of those approaches.

This article defends informed preference-based approaches to welfare evaluations in public policy against four influential objections based on central democratic and liberal values, namely: the objection from respect; the objection from anti-paternalism; the objection from liberal neutrality; and the objection from socio-economic justice. The article argues for two main claims of wide interest to economists, philosophers and policymakers. First, the proffered objections impose plausible adequacy constraints on existing approaches to welfare evaluations in public policy. And second, the proponents of informed preference-based approaches can successfully address those objections and thereby provide economists, philosophers and policymakers with convincing reasons to rely on such approaches.

This PhD thesis focuses on the philosophical foundations of Neuroeconomics, an innovative research program which combines findings and modelling tools from economics, psychology and neuroscience to account for human choice behaviour. The proponents of Neuroeconomics often manifest the ambition to foster radical modifications in the accounts of choice behaviour developed by its parent disciplines. This enquiry provides a philosophically informed appraisal of the potential for success and the relevance of neuroeconomic research for economics. My central claim is that neuroeconomists can help other economists to build more predictive and explanatory models, yet are unlikely to foster revolutionary modifications in the economic theory of choice. The contents are organized as follows. In chapters 1-2, I present neuroeconomists’ investigative tools, distinguish the most influential approaches to neuroeconomic research and reconstruct the case in favour of a neural enrichment of economic theory. In chapters 3-7, I combine insights from neuro-psychology, economic methodology and philosophy of science to develop a systematic critique of Neuroeconomics. In particular, I articulate four lines of argument to demonstrate that economists are provisionally justified in retaining a methodologically distinctive approach to the modelling of decision making. My first argument points to several evidential and epistemological concerns which complicate the interpretation of neural data and cast doubt on the inferences neuroeconomists often make in their studies. My second argument aims to show that the trade-offs between the modelling desiderata that neuroeconomists and other economists respectively value severely constrain the incorporation of neural insights into economic models. My third argument questions neuroeconomists’ attempts to develop a unified theory of choice behaviour by identifying some central issues on which they hold contrasting positions. My fourth argument differentiates various senses of the term ‘revolution’ and illustrates that neuroeconomists are unlikely to provide revolutionary contributions to economic theory in any of these senses.

In recent years, leading public reason liberals have argued that publicly justifying coercive laws and policies requires that citizens offer both adequate secular justificatory reasons and adequate secular motivating reasons for these laws and policies. In this paper, I provide a critical assessment of these two requirements and argue for two main claims concerning such requirements. First, only some qualified versions of the requirement that citizens offer adequate secular justificatory reasons for coercive laws and policies may be justifiably regarded as plausible liberal principles of public justification. And second, the requirement that citizens offer adequate secular motivating reasons for coercive laws and policies is untenable on multiple grounds. Public reason liberals should focus on assessing the justificatory reasons offered for and against coercive laws and policies rather than requiring citizens to offer adequate secular motivating reasons for such laws and policies.

In recent years, several prominent authors have criticized fine-tuning arguments for failing to show that the universe’s purported fine-tuning for intelligent life calls for explanation. In this paper, I provide a systematic categorization and a detailed evaluation of the proffered critiques. I argue that these critiques cast doubt on various instances of fine-tuning reasoning, but fail to undermine fine-tuning arguments’ conclusion that the universe’s purported fine-tuning for intelligent life can be justifiably taken to call for explanation. I then explicate the implications of this result for the ongoing philosophical debate concerning the merits of fine-tuning arguments and the conditions under which specific events or states of affairs are justifiably taken to call for explanation.

This paper critically assesses Rizzo and Whitman’s theory of inclusive rationality in light of the ongoing cross-disciplinary debate about rationality, welfare analyses and policy evaluation. The paper aims to provide three main contributions to this debate. First, it explicates the relation between the consistency conditions presupposed by standard axiomatic conceptions of rationality and the standards of rationality presupposed by Rizzo and Whitman’s theory of inclusive rationality. Second, it provides a qualified defence of the consistency conditions presupposed by standard axiomatic conceptions of rationality against the main criticisms put forward by Rizzo and Whitman. And third, it identifies and discusses specific strengths and weaknesses of Rizzo and Whitman’s theory of inclusive rationality in the context of welfare analyses and policy evaluation.

This paper combines considerations from ethics, medicine and public health policy to articulate and defend a systematic case for mask wearing mandates (MWM). The paper argues for two main claims of general interest in favour of MWM. First, MWM provide a more effective, just and fair way to tackle the ongoing COVID-19 pandemic than policy alternatives such as laissez-faire approaches, mask wearing recommendations and physical distancing measures. And second, the proffered objections against MWM may justify some exemptions for specific categories of individuals, but do not cast doubt on the justifiability of these mandates. Hence, unless some novel decisive objections are put forward against MWM, governments should adopt MWM.

Normative welfare economics commonly assumes that individuals’ preferences can be reliably inferred from their choices and relies on preference satisfaction as the normative standard for welfare. In recent years, several authors have criticized welfare economists’ reliance on preference satisfaction as the normative standard for welfare and have advocated grounding normative welfare economics on opportunities rather than preferences. In this paper, I argue that although preference-based approaches to normative welfare economics face significant conceptual and practical challenges, opportunity-based approaches fail to provide a more reliable and informative foundation for normative welfare economics than preference-based approaches. I then identify and rebut various influential calls to ground normative welfare economics on opportunities rather than preferences to support my qualified defence of preference-based approaches.

In the recent literature across philosophy, medicine and public health policy, many influential arguments have been put forward to support the use of randomization procedures to allocate scarce life-saving resources. In this paper, I provide a systematic categorization and a critical evaluation of these arguments. I shall argue that those arguments justify using RAND to allocate SLSR in fewer cases than their proponents maintain and that the relevant decision-makers should typically allocate SLSR directly to the individuals with the strongest claims to these resources rather than use RAND to allocate such resources.

The critics of rational choice theory frequently claim that RCT is self-defeating in the sense that agents who abide by RCT’s prescriptions are less successful in satisfying their preferences than they would be if they abided by some normative theory of choice other than RCT. In this paper, I combine insights from philosophy of action, philosophy of mind and the normative foundations of RCT to rebut this often-made criticism. I then explicate the implications of my thesis for the wider philosophical debate concerning the normativity of RCT for both ideal agents who can form and revise their intentions instantly without cognitive costs and real-life agents who have limited control over the formation and the dynamics of their own intentions.

Decision theorists have attempted to accommodate several violations of decision theory’s axiomatic requirements by modifying how agents’ choice options are individuated and formally represented. In recent years, prominent authors have worried that these modifications threaten to trivialize decision theory, make the theory unfalsifiable, impose overdemanding requirements on decision theorists, and hamper decision theory’s internal coherence. In this paper, I draw on leading descriptive and normative works in contemporary decision theory to address these prominent concerns. In doing so, I articulate and assess several different criteria for individuating and formally representing agents’ choice options.

The critics of rational choice theory (RCT) frequently build on the contrast between so-called thick and thin applications of RCT to argue that thin RCT lacks the potential to explain the choices of real-world agents. In this paper, I draw on often-cited RCT applications in several decision sciences to demonstrate that despite this prominent critique there are at least two different senses in which thin RCT can explain real-world agents’ choices. I then defend this thesis against the most influential objections put forward by the critics of RCT. In doing so, I explicate the implications of my thesis for the ongoing philosophical debate concerning the explanatory potential of RCT and the comparative merits of widely endorsed accounts of explanation.
