The Bhagavad Gita is one of the foundational texts of Hinduism and probably the one most familiar and popular in the West. The moral problem that motivates the text – is it right to kill members of one’s extended family if they are on the other side in a war?...

Humor and its varied manifestations—jesting joking around, goofing, lampooning, and so on—pervade the human experience and are plausibly regarded as necessary features of interpersonal interactions. As one would expect, these pervasive phenomena occasion philosophical questions. What renders some item or event humorous? Are funny jokes objectiv ...…

The Intergovernmental Panel on Climate Change (IPCC) reports that there is a warming trend in the global climate that is attributable to human activity, with an expected increase in global temperature (given current trends) of 1.5- 4.5 degrees Celsius (2.7-7.2 degrees Fahrenheit). But how do climate scientists reach these conclusions?...…

We’re all familiar with some of the ways that time figures into our political environment. Things such as term limits, waiting periods, deadlines, and criminal sentences readily come to mind. But there are also protocols, accords, mandates, and contracts, and these frequently invoke temporal bounds of various kinds. In fact,...…

There are five people on the track and a runaway trolley that will hit them, and you are on a footbridge over the track with a large person whose body can stop the trolley in its tracks. Should you push the large person to his death to save the five...

John Rawls is easily the most celebrated and influential political philosopher of the 20th Century, and his impact remains remarkably strong today. The central concepts with which his theory of justice begins are now components of the philosophical vernacular: The Original Position, Veil of Ignorance, Primary Goods, and his Two...…

Kant famously asked the question, how is knowledge possible? In her new book, Beyond Concepts: Unicepts, Language, and Natural Information (Oxford University Press, 2018), Ruth Garrett Millikan responds to this question from a naturalistic, and specifically evolutionary, perspective. Millikan, who is distinguished professor emerita at the Unive ...…

My guest today is Christian Miller. Christian is A. C. Reid Professor of Philosophy at Wake Forest University. He is a moral philosopher specializing on character, with special interest in the empirical study of the virtues and vices. He currently directs The Beacon Project, which studies morally exemplars; and he...…

The ancient Maya are popularly known for their calendar, but their concept of time and the metaphysics surrounding that conception are not. In Philosophy of the Ancient Maya: Lords of Time (Lexington Books, 2018), Alexus McLeod reconstructs an ancient Mayan metaphysical system based on key texts and other artifacts plus...…

We all put a great deal of care into protecting, managing, and monitoring our reputation. But the precise nature of a reputation is obscure. In one sense, reputation is merely hearsay, a popular perception that may or may not have any basis in fact. Yet we rely heavily on reputations...

Thomas Kuhn upset both scientists and philosophers of science when he argued that transitions from one scientific framework (or “paradigm”) to another were irrational: the change was like a religious conversion experience rather than a reasoned shift from one theory to another based on the best evidence. But even if...…

The two biggest problems of understanding the mind are consciousness and intentionality. The first doesn’t require introduction. The latter is the problem of how we can have thoughts and perceptions that about other things for example, a thought about a tree, or a perception of a tree. How can mental...…

It’s intuitive to think that statements of the form “lying is wrong” ascribe a property—that of wrongness—to acts of the type lying. In this way, one might think that statements of this kind are much like statements of the form “Bill is left-handed,” which also seems to attribute a property—left-handedness...…

Here’s a true sentence: The number seven is odd. What’s philosophically odd about the sentence is that it seems to imply that there must be numbers, including the number seven just as the truth of The Statue of Liberty is in New York implies that there is such a statue....

Middle-agedness is a curious phenomenon. In many ways, one is at one’s peak and also at the early stages of decline. There is much to do, but also dozens of paths irretrievably untaken. Successes, but also regrets. It’s no wonder that the idea of a midlife crisis is so familiar....

What is it to be moral, to lead an ethically good life? From a naturalistic perspective, any answer to this question begins from an understanding of what humans are like that is deeply informed by psychology, anthropology, and other human-directed perspectives as these are constrained by evolution. In The Geography...…

Epistemology is the area of philosophy that examines the phenomena of and related to knowledge. Traditional core questions include: How is knowledge different from lucky guessing? Can knowledge be innate? Is skepticism a threat, and if so, how should it be countered? And: Is it possible to know something simply...…

Seeing is often a good reason for believing—when things go well. But suppose we have a case like this: Jill believes that Jack is angry, although she has no good grounds for this belief. Nevertheless, when she sees him, she sees his face as angry even though it is neutral....

We all recognize that parenting involves a seemingly endless succession of choices, beginning perhaps with the choice to become a parent, through a sequence of decisions concerning the care, upbringing, acculturation, and education of a child. And we all recognize that many of these decisions are impactful. More specifically, we...…

Social constructionists hold that the world is determined at least in part by our ways of representing it. Recent debates regarding social construction have focused on categories that play important roles in the human social world, such as race and gender. Social constructionists argue that these categories are not biological...…

According to a challenge going back to Plato, democracy is unacceptable as a mode of political organization, because it distributes political power equally among those who are unequal in wisdom. Plato goes on to object that democracies are suspicious of the very idea of expertise in political matters. Long traditions...…

In the 1960’s Thomas Kuhn argued, in The Structure of Scientific Revolutions, that scientists’ choices between competing theories could not be determined by the empirical evidence. Ever since, philosophers of science have debated the role of non-epistemic values and interests in science, generally agreeing that such influences are undesirable e ...…

When Descartes famously concluded “I think, therefore I am”, he took for granted his ability to use the first person pronoun to refer to himself. But how do we come to have this capacity for self-conscious thought? We aren’t born with it, and while we may not be the only...

We are accustomed to the thought that individuals facing dire circumstances may rightfully take use of others’ property in order to save their own lives. For example, one thinks it obvious that in order to avoid freezing to death, a lost mountain hiker may rightfully break into and make use...

A popular way of thinking about the mind and its relation to physical stuff is in terms of computation. This general information-processing approach to solving the mind-body problem admits of a number of different, often incompatible, elaborations. In Physical Computation: A Mechanistic Account (Oxford University Press, 2016), Gualtiero Piccini ...…

When we are thinking about what we ought to do, we are nearly always deciding among options. And we often talk in ways that reflect this; statement about what one ought to do are frequently explicitly statements that identify some act as the one to be performed from a broader...

Shame is a complex social emotion that has a particularly negative valence; in the West it is associated with failure, inappropriateness, dishonor, disgrace. But within the Confucian tradition, there is in addition a distinct, positive variety of moral shame a virtue that, as Bongrae Seok writes, “is not for losers...…

The freedoms prized and secured in a modern liberal democratic societies give rise to significant forms of moral and social diversity. In many cases, these forms of diversity must be dealt with by the state and its citizens. A standard way of trying to address social diversity is to call...

For many cognitive scientists, psychologists, and philosophers of mind, the best current theory of cognition holds that thinking is in some sense computation “in some sense,” because that core idea can and has been elaborated in a number of different ways that are or at least seem to be incompatible...…

Many of the longstanding debates in moral philosophy concern the question of where more theorizing should begin. Some hold that moral theories should start with definitions of moral terms like good; others contend instead that we should begin by identifying the conditions under which an action is right; still others...…

Many environmentalists approach the problem of motivating environmentally friendly behavior from the perspective that nature is good and that we ought to act so as to maximize the good environmental consequences of our actions and minimize the bad ones. An environmental activist turned academic philosopher, Benjamin Hale argues against this...…

Humans engage in a wide variety of collective behaviors, ranging from simple customs like wearing a heavy coat in winter to more complex group actions, as when an audience gives applause at the close of a musical performance. Some of these collective behaviors are cases of imitation, of doing what...…

The idea that the sciences can’t be unified–that there will never be a single ‘theory of everything’–is the current orthodoxy in philosophy of science and in many sciences as well. But different versions of pluralism present very different views of what exactly they are pluralistic about, why sciences cannot be...…

The idea that a political order derives its authority, legitimacy, and justification from some kind of initial agreement or contract, whether hypothetical or tacit, has been a mainstay of political philosophy, at least since Hobbes. Today, the leading approach to theorizing justice–John Rawls’ conception of “justice as fairness”– employs a...…

Are complex phenomena “nothing but the sum of their parts”, or are they “more than the sum of their parts”? Physicists, chemists, and biologists as well as philosophers have long argued on both sides of this debate between the idea of reduction and that of emergence. At this point, argues...

The philosopher (and 1972 presidential candidate) John Hospers once wrote, “justice is getting what one deserves. What could be simpler?” As it turns out, this seemingly simple idea is in the opinion of many contemporary political philosophers complicated enough to be implausible. According to many these theorists, the question of...…

Psychological and philosophical theories of the emotions tend to take the adult emotional repertoire as the paradigm case for understanding the emotions. From this standpoint, the emotions are usually distinguished into two categories: the basic emotions, like fear or happiness, and the higher cognitive emotions, like shame or pride. In...…

We are all familiar with the idea that some persons are disabled. But what is disability? What makes it such that a condition–physical, cognitive, psychological–is a disability, rather than, say, a disease or illness? Is disability always and intrinsically bad? Are disabilities things to be cured? Might disabilities be merely...…

The predictive processing hypothesis is a new unified theory of neural and cognitive function according to which our brains are prediction machines: they process the incoming sensory stream in the light of expectations of what those sensory inputs ought to be. On this view, only prediction errors are fed forward...…

On any mature view, war is horrific. Naturally, there is a broad range of fundamental ethical questions regarding war. According to most moral theories, war is nonetheless sometimes permitted, and perhaps even obligatory. But even an obligatory war may be fought in a morally impermissible way. So it makes sense...…

Why is it controversial to cast light-skinned actress Zoe Saldana as the lead character in a film about the performer Nina Simone? How should we understand the coexisting desire and revulsion of the black body that traces its roots to Thomas Jefferson’s longstanding relationship with his slave Sally Hemings and...…

Political states claim the moral right to rule the persons living within their jurisdiction; they claim the authority to make and enforce laws, establish policies, and allocate benefits and burdens of various kinds. But states also claim rights over their territories. These include rights to establish and protect borders, to...…

The social practice we call science has had spectacular success in explaining the natural world since the 17th century. While advanced mathematics and other precursors of modern science were not unique to Europe, it was there that Isaac Newton, Robert Boyle, and others came up with theories that got modern...…

In the genes vs. environment debate, it is widely accepted that what we do, who we are, and what mental illnesses we are at risk for result from a complex combination of both factors. Just how complex is revealed in Behaving: What’s Genetic, What’s Not, and Why Should We Care?...

Anger is among the most familiar phenomena in our moral lives. It is common to think that anger is an appropriate, and sometimes morally required, emotional response to wrongdoing and injustice. In fact, our day-to-day lives are saturated with inducements not only to become angry, but to embrace the idea...…

There is a long history in philosophy, art and religion of claims about the ineffable from The One in Plotinus to Kant’s noumena or thing-in-itself to Wittgenstein’s famous remark at the end of Tractatus that “whereof one cannot speak, thereof one must be silent.” But even if the ineffable cannot,...…

The pragmatist tradition in philosophy tends to focus on the pioneering work of its founding trio of Charles Pierce, William James, and John Dewey, who together proposed and developed a distinctive kind of naturalist empiricism. Though they disagreed sharply over central issues concerning truth and meaning, the original pragmatists shared...…

The British philosopher and logician Bertrand Russell claimed it is a truism that there are facts: the planets revolve around the sun, 2 + 2 = 4, elephants are bigger than mice. In Against Facts (MIT Press, 2015), Arianna Betti argues that not only is it not a truism that...

Communities of parents who refuse, delay, or selectively decline to vaccinate their children pose familiar moral and political questions concerning public health, safety, risk, and immunity. But additionally there are epistemological questions about these communities. Though frequently dismissed as simply ignorant, misinformed, or superstitious ...…

What do we mean when we claim that something is a cause of something else that smoking causes cancer, that the assassination of Archduke Ferdinand caused World War I, that the 8-ball caused the other billiard ball to go into the side pocket? In Causation, Evidence, and Inference (Routledge 2015),...
