I am a philosopher. Much of my research has focused on perception, drawing on both philosophy and the sciences of the mind. I’ve written about what kinds of things we can perceive; how our perceptions can be influenced by what we already know, suspect, or fear; and the relationships between perception and culture, memory, knowledge, concepts, and language.
I’m also interested in formal and informal epistemology, philosophy of mind, the philosophy of journalism, and political philosophy — and not only for their relationships to perception. I seek to foster analytic philosophy in Spanish, and enjoy writing for a range of venues.
Currently I’m working on two projects. One is on vigilantism and political vision. I was awarded a Guggenheim fellowship in 2023-24 to continue my work on this project. The other is on the various normative pressures on attention that can be found at both large scale inquiries (like the ones reported in news journalism) and individual inquiries (“Why won’t my computer charge?”). This project combines work in analytic epistemology and the philosophy of journalism.
Prof. Kristie Dotson and I won the 2023 Lebowitz prize for our work on norms of attention. Part of prize is a joint session at the APA on this topic. Ours will take place at the 2024 Central Division APA in New Orleans.

What's New
WANDINERG INQUIRY - FORTHCOMING IN THE JOURNAL OF PHILOSOPHY
Available here. Abstract: Inquiry is guided, in the minimal sense that it is not haphazard. It is also often thought to have as a natural stopping point ceasing to inquire, once inquiry into a question yields knowledge of an answer. On this picture, inquiry is both telic and guided. By contrast, mind-wandering is unguided and atelic, according to the most extensively developed philosophical theory of it. This paper articulates a puzzle that arises from this combination of claims: there seem to be plenty ofexamples of inquiry progressing within mind-wandering, yet theories of inquiry and mind-wandering can make wandering inquiry seem impossible or incoherent. I offer several solutions to this puzzle and make the case that taken together, they illuminate a prevalent form of inquiry that the burgeoning literature on that topic overlooks, to its detriment: "low" inquiry - inquiry that progresses spontaneously, without executive control. (September 2024)
THE PHENOMENal Public - Volume 1, Issue 1 of the new journal, political philosophy
Writing this paper was more fun than should be allowed in such endeavors. Don’t miss the illustration of it by Becky Moon!
Abstract: With what modes of mentality can we build a visceral, subjective sense of being in some specific mass-political society? Theorists and political cultivators standardly call upon the imagination – the kind prompted by symbols and rituals, for example. Could perception ever play such a role? I argue that it can, but that perceptions of mass-political publics come with costs of cruelty and illusion that neither democratic theorists nor participants should be willing to pay. The clearest examples of such perceptions are found in fascist political culture. My discussion aims to illuminate what it is about publics, perception, and democracy that makes this so.
TWO NEW PAPERS
One is on inquiry in mind-wandering. The other is on inquiry in journalism, forthcoming in Oxford Studies in Epistemology.
Profile - from Fall 2023
This profile appears in the Jan-Feb 2024 issue of Harvard magazine. It’s by a brilliant journalist I was lucky to get to talk to - Lydialyle Gibson. She covers some of my work and personal history. It shows a throughline connecting my older work in philospohy of perception to more recent work on vigilantism. It doesn’t focus on my inquiry project , or mind-wandering, or the philosophy of journalism, and it doesn’t cover any debates in the philosophy of perception. But not everything can be covered in one profile. As a bonus, you can see some of Becky Moon’s philosophical paintings!
Sea of Perception - Art + Philosophy show
The amazing artist Becky Moon based in St Louis and Seoul has produced a series of paintings and sculptures prompted by the philosophy of perception. In October 2023 co-curated an art show in Emerson Hall, home to Harvard’s philosophy department. Our artists talk is here, and you can see many Moon’s wonderful pieces here.

THE PHENOMENAL PUBLIC
…a talk I wrote during the pandemic on whether it is only possible to grasp the public via imagination, as many political thinkers have assumed (think of Anderson’s “imagined communities”), or whether it is possible to perceive the public, by perceptually experiencing it - even if the perception involves illusions. It now exists as a paper, email me if you’d like to read it.
The PHILOSOPHY OF VIGILANTISM
My paper Vigilantism and Political Vision has been published by a new and awesome journal: Washington University Review of Philosophy, special issue on war and violence. I discuss what “taking the law into one’s own hands” can amount to, the relationships between vigilantes and mobs, vigilantism and self-defense, and vigilantism and social protest. I came to this topic from a piece I wrote in the Los Angeles Review of Books on mob violence, and was drawn in initially by the fascinating range of historical examples and contemporary resonances in global proto-fascist politics. But I also found vigilantism a useful test case for seeing how (and even whether!) an analysis of correct uses of a concept can also explain misuses, abuses and contestations. Not any old conceptual analysis can do these things. Spoiler: this one can! There’s an extended dsicussion of how attributions of vigilantism can mask self-defense, and how attributions of self-defense can mask vigilantism.
PS: Don’t miss the fabulous cover of the special issue, illustrated by wondrous artist and philosopher Becky Moon - she paints to depict philosophical ideas!

New course: Philosophy of journalism
I’m teaching a course this Fall (2021) on the philosphy of journalism, called Truth, Lies and the Press. It’s the first course ever on this topic to be taught in the Philosophy department at Harvard. Syllabus here.
The course is organized around four visions of democracy and the role of journalism in it. We start by considering in chronological order the thinkers who developed these visions: Ida B. Wells-Barnett, Walter Lippmann, John Dewey, and Hannah Arendt. Then we have a chance to discuss specific problems and topics: objectivity; framing; leaks; the Apology movement by historically white newspapers; and what should count as news. In the last segment we turn to challenges posed by social media. It’s a mix of philosophy, social theory, and US history.
The “pre-assignement” is to listen to Ezra Klein interview Nikole Hannah-Jones and Ta-Nehisi Coates on the 1619 project and resulting backlash, as it raises a lot of central questions we’ll discuss in depth along the way: the potentially competing pressures of fact and narrative; the epistemic status of framing; the many guises, promises, and pitfalls surrounding ideas of objectivity; the roles of journalism in shaping narratives around political violence; the rise of professionalized journalism; the varieties of organized lying, and the challenges for journalism of responding to them.
The course is a mix of philosophy, social theory, and US history.
Recent Talks
New paper: The Phenomenal Public, presented at the Global Consciousness forum, organized by Uriah Kriegel.
In mass society, what modes of mentality can be used to get one’s mind around “the public” - the body politic, ‘the People’? Many thinkers have argued that you can’t perceive the public with perceptual experience - instead you have to imagine it (D. Allen, B. Anderson, J. Dewey, W. Lippmann, M. Nussbaum, etc). I discuss various ways to perceptually experience a public in mass society, and discuss the ways that facilitate and anti-facilitate democracy.
Other presentations of this material, as it grows and morphs: Turin on June 16, Reno in early September. Sao Paolo in late September, Sheffield, Barcelona and London School of Economics in October.
Recording of “How can perceptual experiences explain uncertainty?” - on probability and perception, presented at Moshe Bar’s lab.
Two new papers on salience
“Salience Principles for Democracy”. Forthcoming in Sophie Archer, Ed. Salience. Routledge, 2021.
Abstract: I discuss the roles of journalism in aspirational democracies, and argue that they generate set of pressures on attention that apply to people by virtue of the type of society they live in. These pressures, I argue, generate a problem of democratic attention: for journalism to play its roles in democracy, the attentional demands must be met, but there are numerous obstacles to meeting them. I propose a principle of salience to guide the selection and framing of news stories that I argue may help address the puzzle: the public-as-protagonist principle.
“Salience: the stepping stones of inquiry” has become a larger project. Contact me if you want to read it.
Abstract: In an intuitively recognizable sense, some things can be more salient to the mind than others. I develop the notion of an outlook (one kind of clustering of mental states), and analyze the ways that outlooks can influence what becomes salient in the flow of thought. On my analysis, the flow of thought is a flow of embryonic inquiries, and the epistemic contours can be found by considering the many ways that inquiries can be better or worse. Salience structures can be extensions of inquiry, and that is the key to their epistemic evaluability.
Review of Sheridan Hough’s Marvelous book “Kierkegaard’s Dancing Tax Collector”
Hough’s book shares a feature with most novels: It is narrated by someone distinct from its author. It presents an account of Kierkegaardian faith, on which the paragon of faith is the dancing tax collector - someone described by Johannes de Silentio, the pseudonymous author of Fear and Trembling. Faith is inherently joyful, on this account. Which raises a question about whether it is possible to move faithfully through catastrophe. I argue that the literary form of Hough’s book is not an optional extra or a playful bit of whimsy, but a feature needed to display the practical nature of faith as Hough’s narrator understands it. My review is coming out in Syndicate, as part of a book symposium.

What Can Philosophy Contribute to the study of the mind?
In The Philosophers’ Magazine, issue 88. Currently behind a paywall, but you can find the penultimate draft here. This piece is actually written for newcomers to philosophy, especally experimental scientists and people in the literary humanities. I focus on the role of fiction and fictional examples in the philosophy of mind, and highlight three roles for invented situations: posing a loaded question (think of Frank Jackson’s Mary), illustrating a philosphical problem, and testing normative and modal hypotheses. The material on the second of these roles was the focus of my debate with Steven Pinker about the role of the humanities in the philosophy of mind (video available under the “Media” menu), and the material on the third role relates to my debate with Adam Pautz about The Rationality of Perception.
Replies to Lord, Railton and Pautz on The Rationality of Perception
A symposium on The Rationality of Perception will soon be published in Philosophy and Phenomenological Research. The symposiasts are Errol Lord and Peter Railton, who focus on my theory of inference, and Adam Pautz, who raises methodological objections and defends phenomenal conservatism.

Tetralog on Perception and Reason
“The Uneasy Heirs of Acquaintance” is my contribution to a four-way exchange about perception and reason with Bill Brewer, Aniil Gupta, and John McDowell. In this tetralog, we have each written a piece responding to the other three on the topic “Empirical Reason.” My piece locates all of our views in relation to the attempts by Gareth Evans and others he influenced to refigure Russell’s notion of acquaintance in perception. I invite my interlocutors to explain how they would reconcile the primary role of the perceived objects in shaping perceptual experience with the highly constructive nature of perceptual processing. This issue also turns up in my exchange with Christopher Peacocke in “Perception as Guessing vs. Perception as Knowing.”
I’ve also written a reply to my three interlocutors’ comments on me, called “Replies to Brewer, Gupta, and McDowell.”
All eight essays (each of our four original contributions, and each of our replies) appear in the October 2019 volume of Philosophical Issues.
