We are living through a peculiar moment in the long, complicated history of humans and mind-altering substances. After decades of prohibition and stigma, psychedelics have staged a remarkable comeback — not just in underground culture, but in university laboratories, clinical trials, and mainstream news. Researchers are exploring psilocybin and MDMA as treatments for depression and PTSD, and a growing number of philosophers are asking whether the altered states these substances produce might tell us something important about the nature of consciousness, reality, and the self. It turns out that drugs have always been philosophically interesting — but we haven’t always been willing to admit it.

What does it mean to be “sober,” and why has Western philosophy treated sobriety as a prerequisite for truth? If a drug dissolves your sense of self, is there still a philosopher in there doing philosophy — or has philosophy left the building? Is the category of “drug” even coherent, or is it an artifact of colonial trade routes, the war on drugs, and cultural anxieties that have very little to do with what’s actually happening in your brain?

In this episode, we sit down with Justin Smith-Ruiu, Professor of History and Philosophy of Science at the Université Paris Cité, whose new book On Drugs: Psychedelics, Philosophy, and the Nature of Reality takes exactly these questions seriously. Drawing on the history of philosophy, his own experiences, and a genuinely eclectic range of intellectual sources, Smith-Ruiu makes the case that the mainstream philosophical tradition has been too quick to sweep altered states of consciousness under the rug — and that taking them seriously might force us to rethink some of our most basic assumptions about mind, knowledge, and reality.

Grab a drink and join us as we tune in, turn on, and ask what it means to do philosophy with your whole person.

Philosophers have had many conceptions of the future–metaphysical, eschatological, ontotheological, dialectical, fatalistic, idealist, materialist, and more–and these in turn have been central to discussions of free will and determinism, freedom and constraint, hope and despair. But our guest Simon Critchley, Hans Jonas Professor of Philosophy at the New School, is against all of them!

For him, what emerges from Heidegger’s thinking of ecstatic temporality is a radical focus on our historicity, our having-been-ness to inform and improve the present, and this "gritty pessimistic realism” leads him to choose Thucydides over Plato: nothing is ever certain, except for the past, but even the past is a site of contestation and hence not a strong basis on which to make predictions about what is yet to come. Hope for a future is misplaced; instead we must have courage.

So why be “against the future”? Listen in as Simon and the gang discuss the dangers and disasters–ideological, institutional, and philosophical–of investing too much in the idea of the future, and then, after listening to us ramble on about–and against–the future, tell us what you think. Send us your thoughts!

There have been many reports in the last several years of a growing trend of estranged families in the United States. For those who make the decision to go "no contact" (or "low contact") with their family members, the response from non-family members can be a mixed bag of support and judgment... often independent of the person's reasons for making that choice.

What’s going on with the contemporary phenomenon of people going low or no contact with their family members? Is such a decision morally acceptable, or is forgiveness and relationship maintenance something we owe to others, but especially our family? What does a "good" family look like? And why do we so often find ourselves in the position of hoping for the best without any guarantees that things will turn out well?

In this episode, we investigate the ways in which our families shape our identities and how the stories we tell about family relationships often determine how we see and understand others. As you’ll notice throughout the episode, it turns out that nothing gets people going like family! We're joined by Dr. Kiran Bhardwaj, whose work centers on these complex ethical issues and who walks us through some philosophical distinctions that may help in navigating the murky waters of distressed family relations.

Grab a drink and join us as we attempt to think through, rather than simply react to, the long and tangled ties of family.

This week, our co-hosts are joined at the bar by Dr. Robert T. Valgenti, philosopher and professor at the Culinary Institute of America to talk about food, the “gastronomic event,” the ethics and politics of cooking and eating, and what it means to be human.

Anonymity is usually sold as a kind of freedom: the ability to speak without fear, to move through public space without being tracked, to test ideas and identities without immediate consequences. In this episode of Hotel Bar Sessions, the co-hosts pull up stools to ask whether anonymity actually liberates—or whether it more often dissolves responsibility. Starting with Plato’s Ring of Gyges (and the old moral stress test, what would you do if no one could see you?), the conversation traces a familiar worry: that anonymity invites cruelty, petty opportunism, and moral self-deception, while publicity and accountability form part of the “social glue” that keeps a democratic community from fraying.

But the episode refuses the easy conclusion that anonymity is always corrupting. The hosts distinguish anonymity as a shield for the powerless—whistleblowers, survivors, precarious workers, and people exploring vulnerable dimensions of identity—from anonymity as impunity for the powerful. And then the stakes sharpen: when state agents mask themselves, anonymity stops being a personal protection and becomes a political weapon—an engineered unaccountability that makes contestation nearly impossible and turns “rule of law” into theater. The discussion returns again and again to the unequal distribution of exposure: who is forced to be legible, who gets to disappear, and how institutions (and now AI systems) can hide decision-making behind corporate names, bureaucratic opacity, and algorithmic excuses.

The episode closes by arguing for nuance without moral mush. One can oppose masked, unidentifiable state power while still defending privacy and the selective necessity of anonymity for those at risk.

Catastrophe usually sounds like a synonym for disaster—but in this episode, it’s treated as a philosophical concept: a “downturn” that scrambles a world’s legibility and forces a basic question—what can still be believed now? Starting from Greek tragedy (where catastrophe names a plot’s turning point), the conversation traces how ruptures—ancient, modern, natural, political—expose finitude and test the limits (and complicities) of inherited frameworks of reason.

From there, the episode pivots into a philosophy of catastrophe: the work of making horrors intelligible by clarifying the structures that made them possible, while also asking what catastrophe demands ethically—what must never happen again, and what that imperative requires of living, thinking, and teaching after rupture.

Finally, the episode debates philosophy as catastrophe: whether certain ideas don’t merely respond to downturns but actively produce them by breaking prior worlds of sense—recasting what counts as knowledge, power, nature, and the human. The conversation closes with an unsettling contemporary candidate: LLM-generated “philosophy papers” as a potential wheel-smashing shift in how philosophy is produced, circulated, and evaluated.

What do we mean when we talk about intelligence—and who, or what, gets counted as intelligent in the first place? In this episode of Hotel Bar Sessions, our co-hosts pull up stools at the bar to tackle the idea of intelligence(s) as a plural, contested, and deeply political concept.

Starting from a working definition of intelligence as the capacity to navigate a domain toward ends, the conversation quickly fans out: human intelligence, non-human animal intelligence, machine intelligence, and even the question of whether rivers, mountains, or viruses might exhibit their own forms of intelligent “fit.” Our co-hosts wrestle with familiar philosophical fault lines—rationality versus embodiment, instinct versus understanding, adaptation versus explanation—while keeping a sharp eye on the troubling history of intelligence as a ranking device tied to exclusion, hierarchy, and power.

Drawing on phenomenology, feminist philosophy, philosophy of race, AI ethics, and everyday examples ranging from crows to chatbots, the episode asks what’s really at stake when we measure, compare, or deny intelligence. Is intelligence best understood as a single scale, or as an ecology of overlapping capacities shaped by bodies, environments, and worlds? And if machines are already intelligent in their own way, what follows for how we understand ourselves?

Why do AI's fabricated memories "feel" so true?

Hotel Bar Sessions is currently between seasons and while our co-hosts are hard at work researching and recording next season's episodes, we don't want to leave our listeners without content! So, as we have in the past, we've given each co-host the opportunity to record a "Minibar" episode-- think of it as a shorter version of our regular conversations, only this time the co-host is stuck inside their hotel room with whatever is left in the minibar... and you are their only conversant!

AI engineers and designers are currently, and rightly, focused on minimizing the deleterious effects of AI's three primary "memory problems"-- hallucinations, catastrophic forgetting, and bias-- but in this Minibar episode, HBS co-host Leigh M. Johnson argues that none of these problems can be design-engineered away. They are, according to Johnson, baked-in and unavoidable structural elements of any language-based system reliant on an archive.

Borrowing from Jacques Derrida's work on archives, language, and memory, Johnson argues that we should think more seriously about the manner in which LLM's outputs come to us cloaked in the garb of memory. We take AI hallucinations, for example, to be true because they inspire in us a feeling of nostalgia... something that we could have remembered, perhaps even should have remembered, but didn't.

Or didn't we?

Tune in for the first episode of Season 15 on January 23, 2026!
