Anthony Clifford Grayling (born 3 April 1949) is an English philosopher. In 2011 he founded and became the first Master of New College of the Humanities, an independent undergraduate college in London. Until June 2011, he was Professor of Philosophy at Birkbeck, University of London, where he taught from 1991. He is also a supernumerary fellow of St Anne's College, Oxford.

Grayling is the author of around 30 books on philosophy, including The Refutation of Scepticism (1985), The Future of Moral Values (1997), The Meaning of Things (2001), and The Good Book (2011). He is a Trustee of the London Library, a Fellow of the Royal Society of Literature, and a Fellow of the Royal Society of Arts. He is also a director of and contributor to Prospect Magazine.

His main academic interests lie in epistemology, metaphysics, and philosophical logic. He is also associated in the UK with the new atheism movement.

Grayling was born and raised in Luanshya, Northern Rhodesia (now Zambia) within the British expatriate community, while his father worked for the Standard Chartered Bank. He attended several boarding schools there, including Falcon College in Zimbabwe, from which he ran away after being repeatedly and brutally caned. His first exposure to philosophical writing was at the age of twelve, when he found an English translation of the Charmides, one of Plato's dialogues, in a local library. At fourteen, he read G. H. Lewes's Biographical History of Philosophy (1846), which confirmed his ambition to study philosophy; he said it "superinduced order on the random reading that had preceded it, and settled my vocation."

Christopher Eric Hitchens (13 April 1949 – 15 December 2011) was an English American author and journalist whose career spanned more than four decades. Hitchens, often referred to colloquially as "Hitch", was a columnist and literary critic for New Statesman, The Atlantic, The Nation, The Daily Mirror, The Times Literary Supplement and Vanity Fair. He was an author of twelve books and five collections of essays. As a staple of talk shows and lecture circuits, he was a prominent public intellectual, and his confrontational style of debate made him both a lauded and controversial figure.

Hitchens was known for his admiration of George Orwell, Thomas Paine and Thomas Jefferson, as well as for his excoriating critiques of various public figures including Mother Teresa, Bill Clinton, Henry Kissinger and Diana, Princess of Wales. Although he supported the Falklands War, his key split from the established political left began in 1989 after what he called the "tepid reaction" of the Western left to the Rushdie Affair. The September 11 attacks strengthened his internationalist embrace of an interventionist foreign policy, and his vociferous criticism of what he called "fascism with an Islamic face." His numerous editorials in support of the Iraq War caused some to label him a neoconservative, although Hitchens insisted he was not "a conservative of any kind", and his friend Ian McEwan describes him as representing the anti-totalitarian left.

Clinton Richard Dawkins, FRS, FRSL (born 26 March 1941), known as Richard Dawkins, is a British ethologist, evolutionary biologist and author. He is an emeritus fellow of New College, Oxford, and was the University of Oxford's Professor for Public Understanding of Science from 1995 until 2008.

Dawkins came to prominence with his 1976 book The Selfish Gene, which popularised the gene-centered view of evolution and introduced the term meme. In 1982 he introduced an influential concept into evolutionary biology, presented in his book The Extended Phenotype, that the phenotypic effects of a gene are not necessarily limited to an organism's body, but can stretch far into the environment, including the bodies of other organisms.

Dawkins is an atheist, a vice president of the British Humanist Association, and a supporter of the Brights movement. He is well known for his criticism of creationism and intelligent design. In his 1986 book The Blind Watchmaker, he argued against the watchmaker analogy, an argument for the existence of a supernatural creator based upon the complexity of living organisms. Instead, he described evolutionary processes as analogous to a blind watchmaker. He has since written several popular science books, and makes regular television and radio appearances, predominantly discussing these topics. In his 2006 book The God Delusion, Dawkins contends that a supernatural creator almost certainly does not exist and that religious faith is a delusion—"a fixed false belief." As of January 2010 the English-language version has sold more than two million copies and had been translated into 31 languages.

Michael J. Sandel (born March 5, 1953) is an American political philosopher and a professor at Harvard University. He is best known for the Harvard course 'Justice', which is available to view online, and for his critique of John Rawls' A Theory of Justice in his Liberalism and the Limits of Justice (1982). He was elected a Fellow of the American Academy of Arts and Sciences in 2002.

Born in Minneapolis to a Jewish family, which moved to Los Angeles when he was thirteen. A high achiever, he was the President of his senior class at Palisades High School (1971), graduated Phi Beta Kappa from Brandeis University (1975), and received his doctorate from Balliol College, Oxford, as a Rhodes Scholar, where he studied under philosopher Charles Taylor.

Sandel subscribes to a certain version of communitarianism (although he is uncomfortable with the label), and in this vein he is perhaps best known for his critique of John Rawls's A Theory of Justice. Rawls' argument depends on the assumption of the veil of ignorance, which he claims allows us to become "unencumbered selves".
