589: Mary Wollstonecraft
May 07, 2024 14:26 - 11 minutes - 10.2 MBMore at https://www.philosophytalk.org/shows/mary-wollstonecraft. Mary Wollstonecraft is often labeled as a “liberal feminist” because of her concern for women’s rights and conceptions of freedom. But that label narrows her work, which was broadly critical of all social inequalities that distort human relations. So why did Wollstonecraft think that virtue is not truly possible unless we are all free? What did she think was key to the liberation of women? And what were her criticisms of the p...
588: Why Is the World So Weird?
April 23, 2024 20:35 - 9 minutes - 17.6 MBMore at https://www.philosophytalk.org/shows/why-world-so-weird. Quantum mechanics, mathematics, human consciousness.... whichever way you slice it, the universe is weird. How can our conscious minds be made from unconscious atoms? What should we make of quantum entanglement, or the fact that light can be both a particle and a wave? Why is it that there are exactly as many fractions as there are whole numbers? Josh and Ray boggle at the strangeness of it all with Eric Schwitzgebel from UC Ri...
544: What Would Kant Do?
April 22, 2024 00:00 - 10 minutes - 10 MBMore at https://www.philosophytalk.org/shows/what-would-kant-do. German idealist and moral philosopher Immanuel Kant is probably best known for his "Categorical Imperative," which says that you should act following moral rules you could rationally support as universal law. In other words, do only what you would have everyone else do. But are Kant's rules really a good guide to action? Does he have anything to say about things people confront in everyday life, like friendship, manners, or gos...
587: Shakespeare's Outsiders
April 14, 2024 20:28 - 10 minutes - 10.1 MBMore at https://www.philosophytalk.org/shows/shakespeares-outsiders. Over 400 years after his death, Shakespeare is still widely regarded as the greatest dramatist of all time. His many plays tackle questions about power, influence, identity, and moral and social status. His characters—be they villains or heroes—are often disdained because of their race, religion, class, disability, or gender. So what do Shakespeare’s plays reveal about identity and status in his time? How might they shed li...
538: Could Robots Be Persons?
April 07, 2024 00:00 - 8 minutes - 8.15 MBMore at https://www.philosophytalk.org/shows/could-robots-be-persons. As we approach the advent of autonomous robots, we must decide how we will determine culpability for their actions. Some propose creating a new legal category of “electronic personhood” for any sufficiently advanced robot that can learn and make decisions by itself. But do we really want to assign artificial intelligence legal—or moral—rights and responsibilities? Would it be ethical to produce and sell something with the ...
586: Mind Sharing
March 31, 2024 21:51 - 9 minutes - 8.55 MBMore at https://www.philosophytalk.org/shows/mind-sharing. Mind reading might sound like the stuff of science fiction. But in philosophy and psychology, mind reading is something that human beings do whenever we try to guess what another person is thinking. Could it be that people are also natural born mind sharers, unconsciously shaping our behavior to be understood by others? How do we change or exaggerate our actions when others are present? And how can we use these insights to communicat...
585: Margaret Cavendish
March 20, 2024 20:28 - 10 minutes - 9.86 MBMore at https://www.philosophytalk.org/shows/margaret-cavendish. Margaret Cavendish was a writer of poetry, philosophy, polemics, histories, plays, and utopian fiction. She employed many different genres as a way to overcome access barriers for women and build an audience for her subversive philosophical ideas. So, what was so radical about Cavendish's views? Why did she think all matter, even rocks, was at least partially rational? And how did she anticipate the term "epistemic injustice" 4...
536: What Can Virtual Reality (Actually) Do?
March 17, 2024 00:00 - 9 minutes - 9.01 MBMore at https://www.philosophytalk.org/shows/what-can-virtual-reality-actually-do. VR transports users into all kinds of different realities, some modeled on the real world, others completely invented. Though still in its infancy, the technology has become so sophisticated, it can trick the brain into treating the virtual experience as real and unmediated. So what is the most prudent way to employ this cutting edge technology going forward? Could VR help solve real world problems, like impli...
584: The 2024 Dionysus Awards
March 05, 2024 16:34 - 15 minutes - 14.5 MBMore at https://www.philosophytalk.org/shows/2024-dionysus-awards. What movies of the past year challenged your assumptions and made you think about things in new ways? Josh and guest co-host Jeremy Sabol present our annual Dionysus Awards for the most thought-provoking movies of 2023, including: • Best Film about Social Justice that Wonders What Makes a Good Film about Social Justice • Most Disturbing Exploration of a Female Criminal Who Thinks She May Be Innocent • Most Moving Film (or TV...
535: Should All Ages Be Equal?
March 03, 2024 00:00 - 10 minutes - 18.8 MBMore at https://www.philosophytalk.org/shows/should-all-ages-be-equal. Age determines a lot about your position in society—what activities you can do, what benefits you can access, and what rights and responsibilities you have. While it seems appropriate to treat people at different stages of life differently, we also consider certain kinds of unequal treatment unjust. So when should we treat people of different ages differently? And when does it become ageism or age discrimination? When doe...
583: Im Yunjidang
February 21, 2024 22:26 - 10 minutes - 9.21 MBMore at https://www.philosophytalk.org/shows/im-yunjidang. 8th-century Korean philosopher Im Yunjidang was the first Confucian to argue for women’s equality in matters of morality and to claim that women, just like men, can be sages. She also argued that it isn't just what you do that matters morally—it's also how you decide. So what does it mean to be a sage and how does someone become one? How did Im Yunjidang use traditional Confucian texts to argue for women's spiritual equality? And wha...
534: The Social Lives of Robots
February 18, 2024 00:00 - 10 minutes - 9.77 MBMore at https://www.philosophytalk.org/shows/social-lives-robots. Machines might surpass humans in terms of computational intelligence, but when it comes to social intelligence, they’re not very sophisticated. They have difficulty reading subtle cues—like body language, eye gaze, or facial expression—that we pick up on automatically. As robots integrate more and more into human life, how will they figure out the codes for appropriate behavior in different contexts? Can social intelligence be...
195: Lincoln as a Philosopher
February 11, 2024 00:00 - 10 minutes - 9.49 MBMore at http://philosophytalk.org/shows/lincoln. More than any other President, Abraham Lincoln is known for his words, from the Lincoln-Douglass debates to the second inaugural address, as well as his deeds. What was Lincoln's basic philosophy, and did it change over the course of his Presidency? Ken and John welcome back Chicago Public Radio's Resident Philosopher, Al Gini, to celebrate the bicentennial of Lincoln, the man and his ideas.
582: Can A.I. Help Us Understand Babies?
January 31, 2024 22:00 - 9 minutes - 8.51 MBMore at https://www.philosophytalk.org/shows/can-ai-help-us-understand-babies. Artificial intelligence is everywhere in our day-to-day lives and our interactions with the world. And it's made impressive progress at a variety of visual, linguistic, and reasoning tasks. Does this improved performance indicate that computers are thinking, or is it just an engineering artifact? Can it help us understand how children acquire knowledge and develop language skills? Or are humans fundamentally diffe...
581: 20th Anniversary Quiz Night
January 24, 2024 20:58 - 17 minutes - 16.4 MBMore at https://www.philosophytalk.org/shows/20th-anniversary-quiz-night. Philosophy Talk made its radio debut on August 20, 2003 with a live pilot on KALW San Francisco and weekly broadcasts beginning in January 2004. To celebrate two decades on the air, in November 2023 we held our first-ever Quiz Night. Longtime listeners and first-time fans filled KALW's popup space in downtown San Francisco as Director of Research Laura Maguire ran eight teams through the gauntlet of a philosophical pub...
531: The Mysterious Timelessness of Math
January 20, 2024 00:00 - 10 minutes - 9.82 MBMore at https://www.philosophytalk.org/shows/mysterious-timelessness-math. Math is a really useful subject—at least, that's what your parents and teachers told you. But math also leads to scenarios, like Zeno's paradoxes, that seem to inspire skepticism. So why do we believe in math and rely on it to build bridges and spaceships? How can anyone discover the secrets of the universe by simply scribbling numbers on a piece of paper? Is math some kind of magic, or does it have a more ordinary ex...
533: Frege and the Language of Reason
January 14, 2024 00:00 - 10 minutes - 9.55 MBMore at https://www.philosophytalk.org/shows/frege-and-language-reason. At the end of the 19th Century, the German philosopher Gottlob Frege invented a new language, based on mathematics, designed to help people reason more logically. His ideas have had a lasting impact on philosophy, math, computer science, and the study of artificial intelligence. And many of the questions that influenced his thinking are still hotly debated today: How much does language influence the thoughts you can thin...
337: Simone de Beauvoir
January 07, 2024 00:00 - 9 minutes - 9.13 MBMore at http://philosophytalk.org/shows/simone-de-beauvoir. Simone de Beauvoir is often cast as only a novelist or a mere echo of Jean-Paul Sartre. But she authored many philosophical texts beyond The Second Sex, and the letters between her and Sartre reveal that both were equally concerned with existentialist questions of radical ontological freedom, the issue of self-deception, and the dynamics of desire. This episode explores the evolution of de Beauvoir's existential-ethical thinking. ...
580: American Futures (Ken Taylor Memorial Episode)
December 31, 2023 19:46 - 16 minutes - 15.5 MBMore at https://www.philosophytalk.org/shows/american-futures. When Philosophy Talk co-founder Ken Taylor passed away in 2019, he was working on a manuscript titled Farewell to the Republic We Once Dreamed of. Was Ken right to think the American experiment is on the verge of collapse? Are we heading for authoritarian rule, a national divorce, or even a civil war? Or could better days be on the horizon? In Ken’s honor, Josh and Ray devote their end-of-year special to probing the future of the...
579: Impossible Worlds
December 14, 2023 14:50 - 10 minutes - 9.24 MBMore at https://www.philosophytalk.org/shows/impossible-worlds. Philosophers often speculate about possible worlds: ways that things could be. Some of them also believe in impossible worlds: ways that things couldn't be. Are impossible worlds places where strange things happen, or descriptions, or abstract objects, or something else entirely? How can you describe an impossibility without contradicting yourself? Could we imagine worlds where even the laws of logic are different? Josh and Ray ...
525: Nonduality and the Oneness of Being
December 10, 2023 00:00 - 10 minutes - 9.68 MBMore at https://www.philosophytalk.org/shows/nonduality-and-oneness-being. Some branches of Hindu philosophy propose that reality is nondual in nature. Such schools of thought—called advaita schools, from a Sanskrit word meaning “not two”—see the material world either as an aspect of ultimate reality (“Brahman”) or as a mere illusion. So how do we make sense of the appearance of variety in a metaphysics of oneness? Is there room for individual selves within advaita philosophy? What can be kn...
578: In Awe of Wonder
November 30, 2023 16:41 - 11 minutes - 10.5 MBMore at www.philosophytalk.org/shows/awe-wonder. René Descartes said that the purpose of wonderment is “to enable us to learn and retain in our memory things of which we were formerly unaware.” He also said that those who are not inclined to wonder are “ordinarily very ignorant.” So what exactly is wonder, and how is it different from awe? Is wonder at the core of what drives us to search for novel insights? And can we suffer from an excess of wonderment? Josh and Ray stand in awe of Helen d...
529: Microaggressions
November 26, 2023 00:00 - 11 minutes - 10.2 MBMore at https://www.philosophytalk.org/shows/microaggressions. Microaggressions are small comments or questions that may be insulting or hurtful to another person because of their race, gender, sexuality, and so on. Some people consider microaggressions to be a phantom symptom of political correctness and a further sign that society has become “soft,” while others see them as a problematic way of normalizing bigotry. So how do microagressions compare to other types of moral harms? Do they ad...
577: Mary Astell
November 16, 2023 19:07 - 10 minutes - 9.69 MBMore at https://www.philosophytalk.org/shows/mary-astell. Mary Astell (1666–1731) was an English philosopher and writer who advocated for equal rights for women. While she described marriage as a type of “slavery,” she was also a staunch conservative who claimed that women who did marry should accept subordination to their husbands. So what was Astell's vision for the education of women? How did she reconcile her seemingly conflicting views on marriage? And why did philosopher John Locke cri...
576: Zhuangzi—Being One with Ten Thousand Things
November 05, 2023 22:43 - 11 minutes - 10.1 MBMore at www.philosophytalk.org/shows/zhuangzi. Zhuangzi, the 4th-century-BCE Chinese philosopher, was arguably the most important figure in Taoism. He believed that a person’s ideal relationship to the world was to "be one with ten thousand things." So how is someone supposed to achieve this ideal? What is at the core of Zhuangzi's conception of the good life? And how could contemporary western readers benefit from his way of thinking? Josh and Ray welcome back Paul Kjellberg from Whittier C...
528: Referring to the World – Ken's Final Work
October 29, 2023 19:41 - 8 minutes - 7.96 MBMore at https://www.philosophytalk.org/shows/referring-world. On December 2, 2019, Ken Taylor announced that he finally had “an almost complete draft” of a book he had been writing for years. “I think I'll pour a glass of wine to mark the occasion, before plunging back into the work that is still to be done,” he wrote. Tragically and unexpectedly, he died later that same day. Thanks to the hard work and dedication of some colleagues, his book, "Referring to the World: An Opinionated Introduc...
575: Elisabeth of Bohemia
October 17, 2023 20:04 - 9 minutes - 8.78 MBMore at https://www.philosophytalk.org/shows/elisabeth-bohemia. Princess Elisabeth of Bohemia (1618–1680) is best known for her correspondence with René Descartes. In her letters, she articulated a devastating critique of his dualist theory of mind, in particular on the impossibility of mind-body interaction. So what was Elisabeth's own position on the nature of mind? What can we ascertain about her moral and political concerns based on her various correspondences? And how are her ideas stil...
524: The Lives and Ideas of the Vienna Circle
October 15, 2023 00:00 - 8 minutes - 8.04 MBMore at https://www.philosophytalk.org/shows/vienna-circle. The Vienna Circle was a group of early twentieth-century philosophers, mathematicians, logicians, and scientists, best known for developing the theory of scientific knowledge called logical positivism. Although positivism as a project has been largely abandoned, the group's ideas continue to have profound influence on contemporary philosophy of science. So what philosophical theories were proposed by the Vienna Circle? How might the...
574: Can Architecture Be Political?
October 04, 2023 16:17 - 10 minutes - 9.28 MBMore at https://www.philosophytalk.org/shows/can-architecture-be-political. It’s common to judge a piece of architecture based on its functional and aesthetic values, and how the two might complement or compete with one other. It’s less common to judge architecture based on its political values. But can’t a building’s design also express a political viewpoint? Why are different styles of architecture associated with different ideologies? And can a historical edifice's social purpose change o...
523: Disinformation and the Future of Democracy
October 01, 2023 00:00 - 9 minutes - 8.35 MBMore at https://www.philosophytalk.org/shows/disinformation-and-future-democracy. The 2020 election and startling events that followed show that the US is as polarized as ever. Not only is there fundamental disagreement over values and goals, but people can’t seem to agree on the most basic, easily verifiable facts, like who actually won. With so many seemingly living in an alternative reality, how do we continue the business of democracy together? Should we adopt paternalistic policies towa...
520: What Is Masculinity?
September 24, 2023 00:00 - 9 minutes - 8.48 MBMore at https://www.philosophytalk.org/shows/what-masculinity. Strong, in control, and stoic—these are traits of the ideal masculine man. Men who fail to conform to this ideal are often penalized, particularly if they are men of color, queer men, working-class men, or men with disabilities. So how do we create different visions of masculinity that make room for all kinds of men? Should we abandon the idea of masculinity altogether, or would that be throwing out the baby with the bathwater? W...
573: Are We Living in a Simulation?
September 14, 2023 18:02 - 8 minutes - 7.91 MBMore at https://www.philosophytalk.org/shows/are-we-living-simulation. With rapid advances in Virtual Reality technology and the like, it’s now possible for us to become absorbed in completely made-up worlds. We might wonder how soon it will be till we reach a point where VR is so good, we can’t tell it apart from the real world. But what if we’ve already reached that point? How would we know if we were currently living in a simulated reality, or are there always telltale signs? And if we we...
453: Adorno and the Culture Industry
September 10, 2023 00:00 - 11 minutes - 10.7 MBMore at www.philosophytalk.org/shows/culture-industry. What's your favorite movie? Did you watch that season finale last night? No spoilers! Popular cultures pervades modern life. But what if pop culture was actually more pernicious than we ordinarily think? Could it be systematically deceiving us—eroding our ability to think for ourselves and fight for change? That's what the 20th century German philosopher Theodor Adorno thought. The Philosophers get cultured on Adorno's life and thought w...
568: Summer Reading List 2023
September 03, 2023 00:00 - 17 minutes - 15.7 MBWhat books should thoughtful people read this summer? Josh and Ray talk to the authors and editors of new and recent books as they compile their annual Summer Reading List: • Michael Schur, creator of TV's "The Good Place" and author of "How to Be Perfect: The Correct Answer to Every Moral Question" • Lori Gruen, Professor of Philosophy at Wesleyan University and co-editor of "The Good It Promises, The Harm It Does: Critical Essays on Effective Altruism" • Gabriella Safran, Professor of Slav...
93: Georg Hegel
August 27, 2023 00:00 - 7 minutes - 7.12 MBMore at http://philosophytalk.org/shows/hegel. Georg Wilhelm Friedrich Hegel is without doubt one of the most influential philosophers of all time. He has, however, been largely ignored by American "analytic" philosophers of the twentieth century. John in particular, and Ken to a lesser extent, don't know nearly as much about Hegel and his philosophy as they should. They will be lively if somewhat obtuse students for Allen Wood, Stanford's resident expert on virtually all aspects of modern p...
572: Weird Wants
August 16, 2023 14:31 - 9 minutes - 8.69 MBMore at https://www.philosophytalk.org/shows/weird-wants. Philosophers from Thomas Aquinas to Elizabeth Anscombe have claimed that wanting something means seeing the good in it. Even if what you want is bad overall, like procrastinating on important work, you can still desire it for its positive qualities. But don't we sometimes want things because of their badness, not in spite of it? Isn't there joy in doing something totally pointless, or even in breaking the rules? And is it really impos...
571: Making a Better World
August 10, 2023 13:51 - 10 minutes - 9.66 MBMore at https://www.philosophytalk.org/shows/making-better-world. Some philosophers think that morality boils down to one idea: we should make the world better for everyone. But who counts in "everyone"—babies, animals, future people? How can we tell what makes the world better for others? And in an uncertain world, how can anyone gauge the effects of their actions? Josh and Ray try to save the world with acclaimed Princeton philosopher Peter Singer, author of "Ethics in the Real World: 90 E...
519: What Has Replaced Freud?
August 05, 2023 00:00 - 10 minutes - 9.9 MBMore at https://www.philosophytalk.org/shows/what-has-replaced-freud. Although the concept that we can have thoughts and desires hidden from consciousness can be traced back to antiquity, it was Freud who truly popularized it in the twentieth century. Now Freud’s theory of the unconscious mind has mostly been abandoned for being unscientific and lacking in empirical evidence. So what has replaced it? Are newer theories that reference “automatic systems” or “implicit attitudes” any more scien...
570: Hypatia of Alexandria
July 21, 2023 15:25 - 10 minutes - 9.63 MBMore at https://www.philosophytalk.org/shows/hypatia-alexandria. Hypatia of Alexandria, late antiquity public figure and scholar, made significant contributions to mathematics, philosophy, and astronomy. Her embrace of Neoplatonism was seen as such a threat to the political elite in Alexandria that she was murdered by a mob of Christians. So what made her ideas so dangerous and revolutionary for her time? As a woman in Ancient Egypt, how did she exert power over her own narrative? And should...
514: The Arts For All?
July 16, 2023 00:00 - 10 minutes - 9.49 MBMore at https://www.philosophytalk.org/shows/arts-all. When we think of “real” art, we often think of expensive, highbrow pieces that are displayed in museums and galleries, and critiqued by the elite. In fact, people commonly lament that they don’t know enough about art to truly understand or appreciate the works that they encounter. So should art aim to be accessible to everyone? Or is it ever okay to sacrifice accessibility for other competing aims that art can pursue? Do artists have a d...
569: Mexican Philosophy
July 09, 2023 20:51 - 9 minutes - 8.38 MBMore at www.philosophytalk.org/shows/mexican-philosophy. From early feminist Sor Juana Inés de la Cruz to existentialist Emilio Uranga, from Indigenous thought to theorists of aesthetic utopia, Mexican philosophy is full of fascinating figures with brilliant insights. What can we learn from them today about belief, desire, freedom, morality, and education? And do Mexican philosophers speak with one voice or in a complicated harmony, stretching across the centuries? Josh and Ray travel throug...
517: Democracy By Numbers
July 01, 2023 00:00 - 10 minutes - 9.43 MBMore at https://www.philosophytalk.org/shows/democracy-numbers. The United States prides itself on being “the world’s greatest democracy,” which adheres to the principle, “one person, one vote.” Despite this, its elections are often highly contentious—presidents can be elected after losing the popular vote, there is widespread gerrymandering and voter purging, and not everyone has equal representation in the Senate. So what can we do to make elections in the US more fair? And how do we decid...
567: What Is Gender?
June 16, 2023 15:59 - 9 minutes - 8.51 MBMore at https://www.philosophytalk.org/shows/what-gender. Gender is a controversial topic these days, but people can't seem to agree about what gender is. Is it an inner identity, a biological fact, or an oppressive system? Should we respect it or resist it? Should it even be a thing? Josh and guest-host Blakey Vermeule question gender with regular co-host Ray Briggs, co-author of "What Even Is Gender?"
518: The Rhetoric of Big Tech
June 10, 2023 00:00 - 10 minutes - 9.63 MBMore at https://www.philosophytalk.org/shows/rhetoric-big-tech. Big Tech is known for its "disruption" of established industries and changing fundamental aspects of our lives from shopping and delivery to communication and transit. While many welcome these changes, there are also worries about privacy, fairness, and deregulation. So how do tech companies think about what it is they are doing and what justifies it? Who are their philosophical sources, and do they use them responsibly? What ro...
515: Minds and Matter
June 04, 2023 00:00 - 9 minutes - 8.47 MBMore at https://www.philosophytalk.org/shows/minds-and-matter. Everything that seems to have a mind also has a body made of flesh and blood. But if we look at the diversity of animals found in the world, we find a huge variety of species that perceive and interact with the world in very different ways. Is there something all these species have in common? Are neurons and ganglia required, or can evolution generate consciousness in different ways? What can the study of evolutionary biology tel...
566: Can Art Save Us?
May 29, 2023 10:57 - 12 minutes - 11.1 MBMore at https://www.philosophytalk.org/shows/can-art-save-us. The world is facing an unprecedented environmental crisis, and we urgently need good ways to address it. Courageous politicians would help, of course, as might scientific innovations. But how much of the problem is a failure of imagination? Could the arts help us see our way out of the problem? How can literature, painting, and movies redraw the landscape in our minds? Josh and Ray imagine a conversation with Harriet Hawkins, Prof...
565: True Contradictions
May 17, 2023 22:42 - 10 minutes - 9.53 MBMore at https://www.philosophytalk.org/shows/true-contradictions. If you want to tell the truth, you shouldn’t contradict yourself—that’s just common sense. A suspect who was home on the night of the crime can’t have been elsewhere, and whatever the weapon, we can rule out the hypothesis that it was both a candlestick and not a candlestick. But there are philosophers who claim we shouldn’t overgeneralize based on murder mysteries: some contradictions are true. Could a badly written law make ...
513: Are We All to Blame?
May 14, 2023 00:00 - 9 minutes - 8.52 MBMore at https://www.philosophytalk.org/shows/are-we-all-blame. It’s easy to identify the pressing issues facing our world today, but it’s much more difficult to assign responsibility for them. Often the blame is placed on collectives — on entire governments, nations, and societies. But does the responsibility truly all fall to them? How can we identify precisely whose fault it is, for example, that we are experiencing climate change, or that hate crimes occur, or that there is a gender wage ...
213: Søren Kierkegaard
May 07, 2023 00:00 - 11 minutes - 10.1 MBMore at: http://philosophytalk.org/shows/kierkegaard. Philosophy usually suggests a striving for rationality and objectivity. But the Danish philosopher Søren Kierkegaard advocated subjectivity and the leap of faith – his conception of how an individual would believe in God or act in love. Kierkegaard, whose best-known work is "Fear and Trembling," is often considered the father of Existentialism. Ken and John explore the life and thought of this passionate philosopher with Lanier Anderson f...
564: The Power of Prediction
April 25, 2023 21:41 - 11 minutes - 10.4 MBMore at https://www.philosophytalk.org/shows/power-prediction. You’re standing at the top of a mountain, surveying the vast landscape below. The information your senses take in flows to your brain, which processes it to create a representation of the scene. Or does it? What if instead of directly perceiving the world around us, the brain is more like a prediction machine that hallucinates a picture of the world? If that were the case, could we still rely on the so-called “evidence of our sen...
