John Lennox

John Lennox is a mathematics topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand John Lennox rather than just read about it. In short: John Carson Lennox (born 7 November 1943) is a Northern Irish mathematician, bioethicist, and lay theologian. He has written many books on religion, ethics, the relationship between science and God (such as Has Science Buried God and Can Science Explain Everything); he has also participated in public debates with atheists, including Richard Dawkins and Christopher Hitchens.

Key takeaways

John Lennox belongs to mathematics; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect John Lennox to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of John Lennox from memory before moving on to harder problems.

Reference excerpt

John Carson Lennox (born 7 November 1943) is a Northern Irish mathematician, bioethicist, and lay theologian. He has written many books on religion, ethics, the relationship between science and God (such as Has Science Buried God and Can Science Explain Everything); he has also participated in public debates with atheists, including Richard Dawkins and Christopher Hitchens. Lennox earned a doctorate in mathematics from the University of Cambridge, followed by second and third doctorates from the University of Oxford and Cardiff University, respectively. As a professor, Lennox specialised in group theory. He is emeritus professor of Mathematics at the University of Oxford, where he is also Emeritus Fellow in Mathematics and Philosophy of Science at Green Templeton College, and has worked as adjunct lecturer at Wycliffe Hall and at the Oxford Centre for Christian Apologetics. He is also an Associate Fellow of the Saïd Business School and a Senior Fellow at the Trinity Forum.

Early life and education John Carson Lennox was born on 7 November 1943 in Belfast and brought up in Armagh, where his father ran a store. He attended The Royal School, Armagh, and went on to become Exhibitioner and Senior Scholar at Emmanuel College, Cambridge, where in 1962, he also attended the last lectures of C. S. Lewis on the poet John Donne. Lennox obtained a Master of Arts, a Master of Mathematics and a Doctor of Philosophy from the University of Cambridge with the dissertation Centrality and Permutability in Soluble Groups (1970). Lennox was awarded a Doctor of Science degree in mathematics by Cardiff University in 1993 for his research. Lennox also holds a Doctor of Philosophy degree from the University of Oxford (by incorporation) and an M.A. degree in bioethics at the University of Surrey. In addition, he was a Humboldt Fellow at the University of Würzburg and the University of Freiburg.

Career

Upon completing his doctorate, Lennox moved to Cardiff, Wales, becoming a reader in Mathematics at the University of Wales, Cardiff. Lennox is currently the President of OCCA (The Oxford Centre for Christian Apologetics). He also teaches science and religion in the University of Oxford. During his 29 years in Cardiff he spent a year at each of the universities of Würzburg, Freiburg (as an Alexander von Humboldt Fellow), and Vienna, and has lectured extensively in both Eastern and Western Europe, Russia, and North America on mathematics, apologetics, and the exposition of scripture. Lennox is the author of a number of books on the relations between science, religion, and ethics. He has published over 70 peer-reviewed articles on mathematics, co-authored two Oxford Mathematical Monographs, and worked as a translator of Russian mathematics. He has spoken in many different countries, in conferences and as an academic fellow, including numerous trips to the former Soviet Union. On 14 March 2012, he presented an edition of the Lent Talks for BBC Radio Four. Lennox has also given lectures at the Veritas Forum on topics such as the relationship between science and religion, the existence of God, doubt, and the problems of evil and suffering. Additionally, he is a Senior Fellow of the Trinity Forum, a Christian nonprofit organisation that develops leaders to make contributions to cultural renewal.

Debates

Lennox has been part of numerous public debates defending the Christian faith, including debates with Christopher Hitchens, Michael Shermer, Richard Dawkins, Lawrence Krauss, Peter Atkins, Victor Stenger, Michael Tooley, Stephen Law, and Peter Singer.

On 3 October 2007, Lennox debated Richard Dawkins at the Samford University in Birmingham, Alabama, on Dawkins's views expressed in his book The God Delusion. Lennox and Dawkins had a discussion in April 2008 at Trinity College, Oxford, to expand upon topics left undeveloped during The God Delusion Debate. On 9 August 2008, Lennox debated Christopher Hitchens at the Edinburgh International Festival in Edinburgh, Scotland, on the question of whether Europe should jettison its religious past and welcome the "New Atheism". On 23 August 2008, Lennox debated Michael Shermer at the Wesley Conference Centre in Sydney, Australia, on the existence of God. On 21 October 2008, Lennox again debated Dawkins at the Oxford University Museum of Natural History, the site of the 1860 Oxford evolution debate between Thomas Henry Huxley and Samuel Wilberforce. The debate was titled "Has Science Buried God?". The Spectator called the event "Huxley-Wilberforce, Round Two." On 3 March 2009, Lennox debated Hitchens for the second time at Samford University in Birmingham, Alabama, on the question "Is God Great?" The debate addressed the validity of some of Hitchens' claims in his book God is Not Great. On 20 July 2011, Lennox debated Peter Singer at the Melbourne Town Hall in Melbourne, Australia, on the topic "Is There a God?" In August 2021, Lennox was the chief guest for Malhar Fest, hosted by St. Xavier's College, Mumbai.

Personal life Lennox speaks English, Russian, French, Spanish, and German. He is married to Sally and has three children and 10 grandchildren. He has a brother named Gilbert Lennox, previously an elder in Glenabbey Church, Glengormley. The hymn writer and recording artist Kristyn Getty, Gilbert's daughter, is Lennox's niece.

Worked examples

Example 1 — a first encounter with John Lennox

Start with the simplest possible case. Write down what John Lennox claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In mathematics, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to John Lennox before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about John Lennox ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of John Lennox

In research: John Lennox appears in mathematics research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses John Lennox in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: John Lennox is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1943 births, 20th-century British Christian theologians, 20th-century British philosophers, so understanding it makes those chapters shorter.
In everyday life: Look for John Lennox outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
