Our conventional wisdom about animal ethics, as embodied in the animal welfare position, is that animals are not things to whom we can have no moral obligations. Animals who are sentient, or subjectively aware, have a morally significant interest in not suffering. But, because they are not self-aware, they do not as an empirical matter have an interest in continuing to live. So we may use and kill animals as long as we do so ‘humanely’ and do not impose ‘unnecessary’ suffering on them. There are at least two serious problems with our conventional wisdom in this regard. First, because animals are chattel property, we undervalue or ignore their interests in not suffering. Second, we cannot justify the view that animals who are sentient do not have a morally significant interest in continuing to live. If animals are not things and matter morally, our institutionalized exploitation of them cannot be justified, and veganism is a moral imperative.

Do we have free will? In this interview, Helen Steward explains part of her very distinctive approach to the philosophical puzzle concerning free will vs determinism. Steward rejects determinism, but not because she denies that we are not material beings (because, for example, we have Cartesian, immaterial souls that have physical effects). Her reasons for rejecting determinism are very different.

Over the centuries, many philosophers have written about injustice. More recently, attention has turned to a previously little-recognized form of injustice – epistemic injustice. The philosopher Miranda Fricker coined the phrase ‘epistemic injustice’ – an example being when your credibility as a source of knowledge is unjustly downgraded (perhaps because you are ‘just a woman’ of the ‘wrong’ race). This interview with Miranda explores what epistemic injustice is, and why it is important.

Descartes's arguments in support of his claim that the mind is an immaterial substance are examined and found wanting. But despite the flaws in his dualistic view of the mind, Descartes has fascinating and important things to say about how much of human experience involves an ‘intermingling’ of mind and body. There are still philosophical lessons to be learnt from Descartes's legacy.

Here's an overview of one of the more ingenious attempts to criticize religious belief. Antony Flew argues that if the religious won't allow anything to count as evidence against what they believe, then they don't actually believe anything. The religious aren't making false claims; rather, they're not making any claims at all.

We often describe actions as good, bad, right, wrong, fair, unkind, deserved, disrespectful, a bit much, and so on. This article asks: Do these terms describe facts about our actions? And do those facts tell us to perform certain actions and refrain from performing others? If so, what exactly does that mean? And, if not, what are we doing when we describe actions in these various ways?

Is ethics all about rights and duties, or is it about living a happy, flourishing life? For millennia in the West, ethics was about the way to flourish as an individual and a community. The qualities that enable people to live that way are the virtues, and that style of ethics is called Virtue Ethics. In the early modern period, Virtue Ethics went out of fashion and ethics began to focus on right and duties, where rights and duties are demands made against others. In this article I argue that the language of rights and duties has made it almost impossible for people on opposing sides of public policy issues to come to agreement. I defend the return of Virtue Ethics in philosophy, and propose that if it can be adopted by ordinary people, we will have a better chance at overcoming our deep divisions.

How can and does science – and especially neuroscience – inform the philosophical puzzle of mind and body?

Since Plato philosophers have struggled to understand the nature of ethics. It seems different from understanding the world around us, which we do by means of our senses and our sciences. Like mathematics ethics seems different. My brief dialogue seeks to unravel its mystery, and may tell you all you need to know about it.

This piece explores the origins of science fiction in philosophical speculation about the size of the universe, the existence of other solar systems and other galaxies, and the possibility of alien life. Science fiction helps us to grapple with the dizzying possibilities that a vast universe affords, by allowing our imagination to fill in the details.

What should we do about climate change? This article examines the ethical problems that arise from climate change, and considers our obligations and responsibilities to one another, other species and the planet because of global warming.

Narcissistic personality disorder describes people who demonstrate an exaggerated sense of entitlement, lack empathy and crave admiration. But philosopher Simone de Beauvoir argued that, even if a person isn't a pathological narcissist, narcissism can be a strategy that some people use to help them cope with being undervalued. Through examples such as singer-songwriter Taylor Swift, I show how Beauvoir's philosophy gives us a framework to understand some narcissistic behaviour and possibilities for more authentic ways of being in the world.

Could you survive your bodily death by uploading your mind?

That the world we seem to experience around us might be nothing but a simulation – perhaps generated by a demon or super-computer – is a perennial theme in science fiction movies. Muriel Leuenberger explores a recent example.

Plato is often regarded as a founding figure for Western philosophy, and specifically as the inventor of a way of doing philosophy grounded in critical, argumentative reason. This article asks whether Plato's practice of writing myths in his dialogues comes into tension with his canonical reputation. I suggest that resolving this tension may require us to revise our standing ideas about the nature of philosophy and its relationship to myth. Against interpretations that minimize the significance of Plato's myths to his philosophy, I argue that he may have constructed them deliberately as a form of philosophical discourse in their own right.

This article is about nothing. Does that mean it is about something, namely, ‘nothing’? Or is there quite literally no thing that this article is about? Follow the dialogue between characters discussing the nature of non-existence and absences to find out! Along the way there will be tongue twisters, contradictions, paradoxes and riddles, ready to challenge our preconceptions of reality as we embark into the mysterious realm of nothingness.

Monarchy is a form of government that, roughly, dictates that the right to rule is inherited by birth by a single ruler. But monarchy (absolute or constitutional) breaches fundamental moral principles that undergird representative democracy, such as basic moral equality, dignity and desert. Simply put, the monarchs (and their family) are treated as morally superior to ordinary citizens and as a result ordinary citizens are treated in an unfair and undignified manner. For example, monarchs are respected, enjoy dignity, income, opportunity, public office and exalted social status just because of their inherited office, which is due to the mere historical accident of family lineage. Hence, we have good moral reason to abolish monarchy. Finally, I briefly reply to the pragmatic argument for constitutional monarchy, namely, the argument that monarchy can be allowed to play a largely ceremonial role in the context of democracy because it is beneficial for the function of society. As I argue, societies run by presidential democracies can function equally well and, what is more, no matter what the pragmatic reasons for constitutional monarchy are, we still have stronger moral reasons against it. Therefore, it should be abolished.

Jordan Peterson is a darling among conservatives and religious people alike. In defending religious belief as the only bulwark against a return to the dark ages, it becomes obvious that Peterson himself doesn't believe in what he preaches. People, he insists, should believe in the archetypal symbolism that is only revealed through a close reading of the Bible. If atheists would only read scripture with more sophistication they wouldn't so embarrassingly reject religion, and simultaneously threaten the very foundations of Western Civilization. It turns out that it's Peterson who comprehensively ignores symbolism. A simple Sunday school lesson shows this.

Several lines of argument are presented to support the notion that hooved animal rescue is justified, however expensive and controversial. The work of Singer and McNamee is discussed. The article concludes that various breeds have distinct arguments in their favour when it comes to rescue.
