Humanists UK in the context of Andrew Copson

George Edward Moore OM FBA (4 November 1873 – 24 October 1958) was an English philosopher, who with Bertrand Russell, Ludwig Wittgenstein and earlier Gottlob Frege was among the initiators of analytic philosophy. He and Russell began de-emphasising the idealism which was then prevalent among British philosophers and became known for advocating common-sense concepts and contributing to ethics, epistemology and metaphysics. He was said to have had an "exceptional personality and moral character". Ray Monk dubbed him "the most revered philosopher of his era".

As Professor of Philosophy at the University of Cambridge, he influenced but abstained from the Bloomsbury Group, an informal set of intellectuals. He edited the journal Mind. He was a member of the Cambridge Apostles from 1894 to 1901, a fellow of the British Academy from 1918, and was chairman of the Cambridge University Moral Sciences Club in 1912–1944. A humanist, he presided over the British Ethical Union (now Humanists UK) in 1935–1936.

George Gilbert Aimé Murray OM FBA (2 January 1866 – 20 May 1957) was an Australian-born British classical scholar and public intellectual, who served as Regius Professor of Greek at the University of Oxford from 1908 to 1936. He was an outstanding scholar of the language and culture of Ancient Greece, perhaps the leading authority in the first half of the twentieth century. He is the basis for the character of Adolphus Cusins in his friend George Bernard Shaw's play Major Barbara, and also appears as the chorus figure in Tony Harrison's play Fram.

He served as President of the Ethical Union (now Humanists UK) from 1929 to 1930 and was a delegate at the inaugural World Humanist Congress in 1952 which established Humanists International. He was a leader of the League of Nations Society and the League of Nations Union, which promoted the League of Nations in Britain.

New Humanist is a British current affairs magazine, published by Humanists UK and based in London, that focuses on culture, news, philosophy, and science from a sceptical perspective.

A humanist celebrant or humanist officiant is a person who performs humanist celebrancy services, such as non-religious weddings, funerals, child namings, coming of age ceremonies and other rituals. Some humanist celebrants are accredited by humanist organisations, such as Humanists UK, Humanist Society Scotland (HSS), The Humanist Society (US), and the Humanist Association of Canada (HAC).

Faith to Faithless is a non-profit organisation in the United Kingdom dedicated to confronting discrimination against atheists and non-religious people, in particular discrimination towards individuals who have left minority religions. It provides support to people leaving religion and helps them to "come out" to friends and family and gives a platform for individuals to speak out publicly and to find mutual support in the wider atheist, secular and humanist communities. Faith to Faithless advocates for individuals and families leaving any religion, and aims to bring discussion and support for ex-religious people into the public domain.

Since 2017 Faith to Faithless has been incorporated as a programme within Humanists UK, formerly the British Humanist Association, the national charity supporting non-religious people.
