St. Augustine suggested that when we try to grasp the idea of time, it seems to evade us: “What then is time? If no one asks me, I know what it is. If I wish to explain it to him who asks, I do not know.” So is time real or merely an artificial construct? Is time a fundamental or emergent property of our universe or a part of our cognitive apparatus? Do we live in a continuum with a definite past...

Is the red you see indeed the very same red that anyone else does? What is the redness of red even like? These sorts of questions are not just amusing, if worn-out, popular philosophical ponderings. Thinkers in the philosophy of perception take such questions as serious windows into the nature of the world and of the mind. Although we are constantly surrounded by colors, the experience of perceivi...

There is an element of risk – either to ourselves or to others – in almost everything we do. By deciding to go to the grocery store, for example, we take a (very small) risk of getting into a car accident. Many risks are acceptable, of course, but how do we know when a risk is worth taking? The most important decisions, after all, are often risky ones. What about risks to others’ welfare? How do w...

Some claim that the collapse of the Twin Towers on September 11, 2001 was actually caused by a controlled demolition orchestrated by the U.S. government. Dramatic conspiracy theories of this kind are all over the place, but they are often dismissed as crazy. Sometimes, however, they turn out to be true: the NSA, as we have learned, conducted secret surveillance of millions of people for more than...

The United States recently threatened military action against Syria in response to the Syrian government’s alleged use of chemical weapons. Similar threats have been made against states suspected of trying to develop nuclear arsenals such as North Korea and Iran. Yet the U.S., the U.K., France, Russia, and China have thousands of active nuclear weapons of their own. Is there a morally significant...

Many goals are too complex for one person to accomplish alone. Every day, we pool together our planning abilities with those around us to get things done. It’s clear that without shared agency, none of our familiar social institutions could exist. However, philosophers are in disagreement about what shared agency actually entails. What is it about collective action that’s unique, and why does it c...

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 Beauvoi...

What does gender have to do with science? The obvious answer is ‘nothing.’ Science is the epitome of an objective, rational, and disinterested enterprise. But given the history of systemic under-representation of women in science, what does it mean that science answers almost exclusively to the methodologies of men? Has male domination contributed certain unfounded assumptions or cognitive biases...

Did you really want to eat that last piece of cake, or were you secretly thinking about your mother? Sigmund Freud, who might have suggested the latter, established the unconscious mind as a legitimate domain for scientific research. He was the first to seriously study dreams and slips of the tongue, and he proposed that neurotic behavior could be explained by beliefs and desires that we repress....

Ever since John Locke, philosophers have wondered about memory and its connection to the self. Locke believed that a continuity of consciousness and memory establish a “self” over time. Now psychology is weighing in with new research suggesting that the relationship between memory and the self is even more complicated than that. But what’s the connection between memory and the self? Can the self b...

It seems reasonable to believe that we can only be blamed or praised for actions that are under our control. Nevertheless, in many concrete scenarios, we’re inclined to base our moral assessment of people on circumstances that are ultimately beyond their control. Blind chance, or “moral luck,” as philosophers call it, may determine the difference between, say, murder and attempted murder. But do w...

A new year offers an opportunity to reflect on the significant events of the previous year.  But what ideas and events took shape over the past twelve months that have prompted us to question our assumptions and to think about things in new ways?  Join John, Ken, and their special guests as they celebrate the examined year with a philosophical look back at 2013. • The Year in Philosophy and Gender...

If we couldn’t trust each other, our lives would be very different. We trust strangers not to harm us, we trust our friends to take care of our most prized possessions, we even trust politicians (sometimes) to come through on their campaign promises. But trust may also come at a high cost: it can leave us vulnerable to lies, deception, and blackmail. So is it reasonable for us to be so trusting? A...

In most Western democracies, religions are exempt from certain rules and regulations that most other organizations have to follow. For example, in the US, religious organizations are not required to pay taxes or follow non-discrimination employment laws. Some faithful go so far as to argue that their religious freedom means they shouldn’t have to provide birth control to their employees. But does...

All over the world, people are living longer and having fewer children than ever before. In less than two decades, one fifth of the US population will be over 65 years old. So what do these radically changed demographics mean for how we re-imagine the shape of a human life? Should we think of the rapidly increasing older population as a blessing or a burden? And what kinds of changes should we mak...

Science aims tell us something about nearly everything, from the atoms in our cells to the motions of the stars. It assumes that knowledge is good for its own sake, and therefore takes as its sole purpose the acquisition of knowledge. But shouldn’t knowledge serve practical and ethical concerns, like ending conflict and feeding the hungry? Could some knowledge be interesting, but ultimately irrele...

A trolley is approaching a track junction, and you happen to be standing by the switch. If you do nothing, the trolley will kill a number of innocent children playing on the tracks.  If you throw the switch, it will kill only one fat man, who is sleeping on the tracks. The so-called Trolley Problem sheds light on many claims in moral philosophy: utilitarian positions (doing what’s best for the gre...

We are often taught that vengeance is a reprehensible or unworthy motivation and that, as a result, pursuing revenge should not be the method of choice when meting out punishment for crimes. Incarceration and other penalties, according to this view, can only be justified in as much as they protect society, rehabilitate criminals, or deter further crime. But are these approaches to punishment reall...

Descartes considered the mind to be fully self-transparent; that is, he thought that we need only introspect to know what goes on inside our own minds. More recently, social psychology has shown that a great deal of high-level cognition takes place at an unconscious level, inaccessible to introspection. How then do we gain insight into ourselves? How reliable are the narratives that we construct a...

Today, the term ‘cynic’ brings to mind a person who has little or no faith in the goodness of the human race. In ancient Athens, however, it meant something quite different: one who rejects all social conventions in order to live in accordance with nature. The Cynics believed that such a life was necessary for freedom and virtue. Why did they think so? What are the most important tenets of Cynic p...

From Aristotle and Kant to Hume and Darwin, philosophers and scientists have long denied the idea that animals are capable of acting for moral reasons. Yet empirical evidence suggests that many animals have rich emotional lives, and some even demonstrate distinctly altruistic or empathetic behavior. So how should we interpret this behavior? Do the moral feelings of animals suggest they are capable...

Philosophy Talk debuted on KALW 91.7 FM in San Francisco in August 2003, with regular broadcasts beginning in early 2004. Over the course of a decade the Philosophers, their guests, and their listeners have discussed and debated everything from the meaning of life to pre-emptive military strikes and baseball. To celebrate ten years on the air, John and Ken listen back to some of their favorite con...

Gangnam style, Lolcats, and Chuck Norris’ superhuman feats are all memes – units of cultural transmission – that spread through the internet. But when the term was originally coined, memes were posited as vehicles of a kind of evolution, similar to genes and biological evolution. So are the memes that colonize our brains simply those that survive natural selection? Don’t we get any say in the viru...

We know what it means for a painting to be beautiful. But what about a life? Like great works of art, great people exhibit style, originality, and creativity. Maybe, then, to live well is just to practice an ART of living. But what do the values that are important to a good life – happiness, moral goodness, or friendship, for example – have to do with aesthetic beauty? Aren’t the qualities that ma...

All there is in the world is physical stuff. That is the fundamental assumption of the materialist standpoint, and the picture given to us by science. But if there is no immaterial soul that survives the death of the body, no other realm to bestow meaning on our lives, how can we avoid despairing in light of this apparent pointlessness? Is there any way we can build meaning from the naturalistic b...
