This is a short introduction to ontological arguments. It begins with a brief characterization of ontological arguments that proceeds mainly by way of example. The rest of the discussion is given over to consideration of what looks like a very simple ontological argument. This consideration turns up many of the issues that arise when more complex ontological arguments are examined.

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.

Proponents of same-sex marriage often defend their view by appealing to the concept of justice. But a significant argument from justice against same-sex marriage can be made also, as follows. Heterosexual union has special social value because it is the indispensable means by which humans come into existence. What has special social value deserves special recognition and sanction. Civil ordinances that recognize same-sex marriage as comparable to heterosexual marriage constitute a rejection of the special social value of heterosexual unions, and to deny such special social value is unjust.

In issue 4, Mark piper presented the famous problem of evil, which appears to show that there is no God, that is to say, no all-powerful, all-knowing and all-good being. Here James Franklin suggests that there may, after all, be a solution to the problem.

This article is my latest attempt to come up with a minimal version of my evolutionary theory of fairness, previously summarized in my book Natural Justice. The naturalism that I espouse is currently unpopular, but Figure 1 shows that the scientific tradition in moral philosophy nevertheless has a long and distinguished history. John Mackie's Inventing Right and Wrong is the most eloquent expression of the case for naturalism in modern times. Mackie's demolition of the claims made for a priori reasoning in moral philosophy seem unanswerable to me.

Every one of us has had some interaction with pregnancy, having been pregnant ourselves or having been the result of someone else's pregnancy. Pregnancy is a source of fascinating philosophical issues, yet has been historically underexplored. In this article, I examine why this might be, and propose how to proceed in the investigation within the context of philosophizing today.

A few years ago, I, an American, was giving a talk at a political philosophy conference in the United Kingdom. My topic was religion in democratic politics, and I delivered what I thought was a splendid line of argument supporting the idea that religion has at most a highly constrained role to play in democratic politics. The audience was appreciative enough, but during the question and answer session, there emerged the charge that my paper had addressed a uniquely ‘American’ problem, a problem that was not of general significance to political philosophers outside of the United States. I replied that although the political scene in the contemporary United States provides many high-profile examples of the problem I had been addressing, the general problem of religion in politics confronts democracy as such. I then provided some cases from outside America in which the problem shows itself: the public slaying of Theo Van Gough, the controversy surrounding the publication of cartoon representations of Muhammad in Denmark, the reemergence of religiously-affiliated and reactionary political parties throughout Europe, and so on. Yet for the most part my audience remained unmoved.

The claim that God is a person or personal is, perhaps, one of the most fundamental claims which religious believers make about God. In Hinduism, Brahma, Vishnu and Shiva are represented in person-like form. In the Hebrew Bible/Old Testament God walks in the Garden of Eden (Genesis 3:8), experiences emotions (e.g. Isaiah 61:8), and converses with human beings (e.g. Job 38–41). In the New Testament, God communicates with his people, usually by means of angels or visions (e.g. Matthew 1:20–21), and retains the ability to speak audibly, as he does to Paul on the Damascus road (Acts 9:4–6). And, in the Qur'an, Allah is said to have a face and two hands (e.g. Qur'an 38:75), to see, and to sit on a throne (e.g. Qur'an 57:4). Many believers today would still claim that, among other things which God can do, he loves those who believe in him (e.g. Ephesians 5:29; I Peter 5:7; Qur'an 1:3) and responds to their prayers (e.g. Matthew 7:7–8; Mark 11:24; Qur'an 11:61).

People prefer certainty. There's a psychological need to explain events or phenomena rather than accept one's ignorance, to say ‘I don't know’ when faced with insufficient evidence.

Tim Crane responds to the several recent attacks on religion made by Richard Dawkins, Sam Harris, et al.

Can you know something that isn't true?

Phillip Johnson introduces the debate over intelligent design.

Do some people have a paranormal power to ‘see’ into the future? There are innumerable anecdotes of events foretold, of course. But is there any scientific evidence of the ability? Fiona Steinkamp, a leading investigator of the paranormal, believes there is.

Thinking Tools is a regular feature that introduces pointers on thinking clearly and rigorously

A common answer to the title question is: being highly competent in a wide range of academic disciplines, as shown by having a large number of good exam results. Is this acceptable?

Osama bin Laden means well. This is evident from his declarations, juridical decrees, lectures, epistles, and written reminders, which Bruce Lawrence has made available in Messages to the World: The Statements of Osama Bin Laden (2005; hereafter referred to by the page numbers in parentheses) a single volume. Duty, Osama claims, compels Muslims' support for jihad against the ‘Crusader–Jewish Alliance’ (7, 23). But many attack his goals and behavior as immoral. Initiatives he has supported or directed represent his strategy for fulfilling his duty and demonstrate its apparent immorality at the same time: notably, attacks on U.S. embassies, the 9/11 attacks, and more recently an alleged plot to detonate hydrogen peroxide bombs in public transportation venues. Moreover, his willingness to kill innocents generally is self-evidently wrong, as is his blanket hatred of Jews, Americans, and Christians (56, 87); although on one occasion he has declared that ‘many in the West are polite and good people’ (142).

In the philosophy of mind, zombies often make an appearance. It seems we can conceive of zombies — beings physically exactly like ourselves but lacking conscious experience. There may not actually be any zombies, of course. But the suggestion that they could exist does at least seem to make sense. Or does it? Robert Kirk investigates.

What is art? Marcel Duchamp made this question pertinent when he developed his ‘Readymades’: ordinary, manufactured objects that he presented as art. In this paper, I use pragmatics – the branch of linguistics concerned with language use in context, and which has its historical roots in the philosophy of language – to argue that, if we accept that art is a form of communication, from artist to audience, then Duchamp was correct to claim that anything can be art, so long as it is presented as such.

People often assume that everyone can be divided by sex/gender (that is, by physical and social characteristics having to do with maleness and femaleness) into two tidy categories: male and female. Careful thought, however, leads us to reject that simple ‘binary’ picture, since not all people fall precisely into one group or the other. But if we do not think of sex/gender in terms of those two categories, how else might we think of it? Here I consider four distinct models; each model correctly captures some features of sex/gender, and so each is appropriate in some contexts. But the first three models are inadequate when tough questions arise, like whether trans women should be admitted as students at a women's college or when it is appropriate for intersex athletes to compete in women's athletic events. (‘Trans’ refers to the wide range of people who have an atypical gender identity for someone of their birth-assigned sex, and ‘intersex’ refers to people whose bodies naturally develop with markedly different physical sex characteristics than are paradigmatic of either men or women.) Such questions of inclusion and exclusion matter enormously to the people whose lives are affected by them, but ordinary notions of sex/gender offer few answers. The fourth model I describe is especially designed to make those hard decisions easier by providing a process to clarify what matters.

Griefbots are chatbots designed to assist individuals in coping with the loss of a loved one by offering a digital replica of the departed. Navigating grief is a deeply transformative and vulnerable journey intricately tied to one's well-being. Do griefbots aid in the grieving process, or do they complicate it? To address these questions, this article blends insights from philosophy and neuroscience to explore the nature of grief as a means to clarify the ethical dimensions surrounding the use of griefbots.
