We argue that although art has no systematic conventions for conveying knowledge in the way science does, the arts often play an important epistemic role in the production and understanding of scientific knowledge. We argue for what we call weak scientific cognitivism, the view that the production and distribution of scientific knowledge can benefit from engagement with art. We present a range of cases that illustrate a variety of epistemic functions of art relevant to scientific practice, and respond to influential objections from anti-cognitivists that purport to show that art has no epistemic value.

This paper introduces the concept of linguistic hijacking, the phenomenon wherein politically significant terminology is co-opted by dominant groups in ways that further their dominance over marginalized groups. Here I focus on hijackings of the words “racist” and “racism.” The model of linguistic hijacking developed here, called the semantic corruption model, is inspired by Burge’s social externalism, in which deference plays a key role in determining the semantic properties of expressions. The model describes networks of deference relations, which support competing meanings of, for example, “racist,” and postulates the existence of deference magnets that influence those networks over time. Linguistic hijacking functions to shift the semantic properties of crucial political terminology by causing changes in deference networks, spreading semantics that serve the interests of dominant groups, and weakening the influence of resistant deference networks. I consider an objection alleging the semantic corruption model gets the semantic data wrong because it entails those who hijack terms like “racist” speak truly, whereas it’s natural to see such hijacking misuses as false speech about racism. I then respond to this objection by invoking the framework of metalinguistic negotiation proposed by Plunkett and Sundell.

This book investigates the impact of misinformation and the role of truth in political struggle. It develops a theory of objective truth for political controversy over topics such as racism and gender, based on the insights of intersectionality, the Black feminist theory of interlocking systems of oppression. Truth is defined using the tools of model theory and formal semantics, but the theory also captures how social power dynamics strongly influence the operation of the concept of truth within the social fabric. Systemic ignorance, propagated through false speech and misinformation, sustains oppressive power structures and perpetuates systemic inequity. Truth tends to empower marginalized groups precisely because oppressive systems are maintained through systemic ignorance. If the truth sets people free, then power will work to obscure it. Hence, the rise of misinformation as a political weapon is a strategy of dominant power to undermine the political advancement of marginalized groups.

Do psychological traits predict philosophical views? We administered the PhilPapers Survey, created by David Bourget and David Chalmers, which consists of 30 views on central philosophical topics (e.g., epistemology, ethics, metaphysics, philosophy of mind, and philosophy of language) to a sample of professional philosophers (N = 314). We extended the PhilPapers survey to measure a number of psychological traits, such as personality, numeracy, well-being, lifestyle, and life experiences. We also included non-technical ‘translations’ of these views for eventual use in other populations. We found limited to no support for the notion that personality or demographics predict philosophical views. We did, however, find that some psychological traits were predictive of philosophical views, even after strict correction for multiple comparisons. Findings include: higher interest in numeracy predicted physicalism, naturalism, and consequentialism; lower levels of well-being and higher levels of mental illness predicted hard determinism; using substances such as psychedelics and marijuana predicted non-realist and subjectivist views of morality and aesthetics; having had a transformative or self-transcendent experience predicted theism and idealism. We discuss whether or not these empirical results have philosophical implications, while noting that 68% of our sample of professional philosophers indicated that such findings would indeed have philosophical value.
