In Defense of Practical Reasons for Belief

Many meta-ethicists are alethists: they claim that practical considerations can constitute normative reasons for action, but not for belief. But the alethist owes us an account of the relevant difference between action and belief, which thereby explains this normative difference. Here, I argue that two salient strategies for discharging this burden fail. According to the first strategy, the relevant difference between action and belief is that truth is the constitutive standard of correctness for belief, but not for action, while according to the second strategy, it is that practical considerations can constitute motivating reasons for action, but not for belief. But the former claim only shifts the alethist's explanatory burden, and the latter claim is wrong—we can believe for practical reasons. Until the alethist can offer a better account, then, I argue that we should accept that there are practical reasons for belief.     

Implicit racial bias and epistemic pessimism

Implicit bias results from living in a society structured by race. Tamar Gendler has drawn attention to several epistemic costs of implicit bias and concludes that paying some costs is unavoidable. In this paper, we reconstruct Gendler’s argument and argue that the epistemic costs she highlights can be avoided. Though epistemic agents encode discriminatory information from the environment, not all encoded information is activated. Agents can construct local epistemic environments that do not activate biasing representations, effectively avoiding the consequences of activation. We conclude that changing our local environments provides a way to avoid paying implicit bias’s epistemic costs.     

Rules for Reasoning from Knowledge and Lack of Knowledge

In this paper, the traditional view that argumentum ad ignorantiam is a logical fallacy is challenged, and lessons are drawn on how to model inferences drawn from knowledge in combination with ones drawn from lack of knowledge. Five defeasible rules for evaluating knowledge-based arguments that apply to inferences drawn under conditions of lack of knowledge are formulated. They are the veridicality rule, the consistency of knowledge rule, the closure of knowledge rule, the rule of refutation and the rule for argument from ignorance. The basic thesis of the paper is that knowledge-based arguments, including the argument from ignorance, need to be evaluated by criteria for epistemic closure and other evidential rules that are pragmatic in nature, that need to be formulated and applied differently at different stages of an investigation or discussion. The paper helps us to understand practical criteria that should be used to evaluate all arguments based on knowledge and/or ignorance.

On Łukasiewicz's Four-Valued Modal Logic

ukasiewicz's four-valued modal logic is surveyed and analyzed, together with ukasiewicz's motivations to develop it. A faithful interpretation of it in classical (non-modal) two-valued logic is presented, and some consequences are drawn concerning its classification and its algebraic behaviour. Some counter-intuitive aspects of this logic are discussed in the light of the presented results, ukasiewicz's own texts, and related literature.     

Creativity and genius as epistemic virtues: Kant and early post-Kantians on the teachability of epistemic virtue

There is a classical paradox in education that also affects the epistemic virtues: the paradox inherent in the demand to develop general strategies for training persons to be free and creative individuals. This problem becomes particularly salient with respect to the epistemic virtue of creativity, the more so if we consider a radical form of creativity, namely, genius. This paper explores a historical constellation in which rigorous claims about the standards for knowledge and morality were developed, along with a highly influential notion of genius: the philosophy of Kant and of immediate post-Kantian philosophers. The paper shows how in this historical moment came together a new notion of “science,” a theory of “genius” and of virtues, and an analysis of the promises and difficulties inherent in educating a virtuous or creative individual. In this constellation of ideas, there also emerges a potentially fruitful account of how to teach intellectual creativity.     

Introduction to the symposium “What makes a philosopher (good or bad)? Philosophical virtues and vices: Past and present”

The main ambition of the eight articles in this collection is to bring together two currently distinct bodies of literature—on scholarly virtues and vices in the sciences and the humanities, and on epistemic virtues and vices—and to jointly connect them to recent work in (revisionary) historiography of philosophy. This introduction briefly reflects on this ambition, providing background and context, and offers a short overview of the eight articles.     

Epistemic deontology and the Revelatory View of responsibility

According to Universal Epistemic Deontology, all of our doxastic attitudes are open to deontological evaluations of obligation and permissibility. This view thus implies that we are responsible for all of our doxastic attitudes. But many philosophers have puzzled over whether we could be so responsible. This paper explores whether this puzzle can be resolved, and Universal Epistemic Deontology defended, by appealing to a view of responsibility it calls the Revelatory View. On that view, an agent is responsible for something when it reveals the kind of person the agent is. The paper explores four ways of developing the Revelatory View and argues that none of the views ultimately defends Universal Epistemic Deontology.     

Understanding the relation between the need and ability to achieve closure: A single paper meta-analysis assessing subscale correlations

The need for closure and the ability to achieve closure are generally thought to be independent from one another. However, previous researchers have found inconsistent relations between these two variables, possibly due to measurement scale modifications that slightly shifted how the underlying constructs were assessed. The present research attempted to address some of these methodological issues with previous research by conducting a single-paper meta-analysis on the correlations between the ability to achieve closure scale and the full need for closure scale and each of its five subscales. Across six university student samples (N = 1983), the full need for closure scale and most of its subscales were significantly negatively correlated with the ability to achieve closure. This finding suggests that the ability to achieve closure affects the costs and benefits of closure and therefore, consistent with lay epistemic theory, the ability to achieve closure predicts individual differences in the need for closure.     

Social values influence the adequacy conditions of scientific theories: beyond inductive risk

The ‘death of evidence’ issue in Canada raises the spectre of politicized science, and thus the question of what role social values may have in science and how this meshes with objectivity and evidence. I first criticize philosophical accounts that have to separate different steps of research to restrict the influence of social and other non-epistemic values. A prominent account that social values may play a role even in the context of theory acceptance is the argument from inductive risk. It maintains that the more severe the social consequences of erroneously accepting a theory would be, the more evidence is needed before the theory may be accepted. However, an implication of this position is that increasing evidence makes the impact of social values converge to zero; and I argue for a stronger role for social values. On this position, social values (together with epistemic values and other empirical considerations) may determine a theory’s conditions of adequacy, which among other things can include considerations about what makes a scientific account unbiased and complete. I illustrate this based on recent theories of human evolution and the social behaviour of non-human primates, where some of the social values implicated are feminist values. While many philosophical accounts (both arguments from inductive risk and from underdetermination) conceptualize the relevance of social values in terms of making inferences from evidence, I argue for the need for a broader philosophical framework, which is also motivated by issues pertaining to scientific explanation.
