C.S. Lewis' famous work on the nature of love divides love into four categories: affection, friendship, eros and charity. The first three are loves which come naturally to the human race. Charity, however, the gift-love of God, is divine in its source and expression, and without the sweetening grace of this supernatural love, the natural loves become distorted and even dangerous.

For many years an atheist, C. S. Lewis vividly describes the spiritual quest that convinced him of the truth and reality of Christianity, in his famous autobiography. "In the Trinity Term of 1929 I gave in, and admitted that God was God...perhaps the most dejected and reluctant convert in all England." Thus Lewis describes memorably the crisis of his conversion. Surprised by Joy reveals both that crisis and its momentous conclusion that would determine the shape of Lewis' entire life.

For centuries people have been tormented by one question above all: if God is good and all-powerful, why does he allow his creatures to suffer pain? And what of the suffering of animals, who neither deserve pain nor can be improved by it? The greatest Christian thinker of our time sets out to disentangle this knotty issue. With his signature wealth of compassion and insight, C. S. Lewis offers answers to these crucial questions and shares his hope and wisdom to help heal a world hungry for a true understanding of human nature.

C.S. Lewis's dazzling allegory about heaven and hell - and the chasm fixed between them - is one of his most brilliantly imaginative tales, as he takes issue with the ideas in William Blake's ‘The Marriage of Heaven and Hell'.

For C. S. Lewis, reason and logic are the sensible way to approach faith and ethics. Much of the 20th century's ills are caused by ill-founded beliefs and opinions. Lewis' original approach remains as vital today as ever. He is able to take the most convoluted subject, turn it side on and shed bright illumination on it. To be able to see along things rather than at them - just like a beam of sunlight that invades the darkness of a toolshed - is, to Lewis, the way to understanding.

2012 marks the 60th anniversary of the publication of C. S. Lewis’s classic, Mere Christianity. Having sold over half a million copies in the UK alone, his overview of Christianity has been imitated many times, but never outdone. Mere Christianity brings together Lewis’s legendary broadcasts from the war years; talks in which he set out simply to ‘"explain and defend the belief that has been common to nearly all Christians at all times."

This is an extensive collection of short essays and other pieces by C. S. Lewis that have been brought together in one volume for the first time. As well as his many books, letters, and poems, Lewis also wrote a great number of essays and shorter pieces on various subjects.

In this essay collection we find a treasure trove of Lewis' reflections on diverse topics.

C S Lewis's philosophical defence of Natural Law (absolute morality) - without which human beings are reduced to less than fully human, and are, thus ‘abolished'. CS Lewis argues that objective value actually exists and that to believe otherwise is to create nonsense. Human beings appreciate values such as beauty and goodness because such things are part of reality - but if absolute morality is denied there will not be any progress for mankind as the things that matter most will be explained away.

Have we been taught to discount the veracity and deeper meaning of our emotional resonance with the world around us? In The Abolition of Man, C.S. Lewis looks at the curriculum of the English "prep school" and begins to wonder if this subliminal teaching has indeed produced a generation who discount such a nature.

Written after his wife's tragic death as a way of surviving the "mad midnight moments", A Grief Observed is C.S. Lewis's honest reflection on the fundamental issues of life, death, and faith in the midst of loss. This work contains his concise, genuine reflections on that period.

C. S. Lewis was a profound thinker with the rare ability to communicate the philosophical and theological rationale of Christianity in simple yet amazingly effective ways. God in the Dock contains 48 essays and 12 letters written by Lewis between 1940 and 1963 for a wide variety of publications.

Lewis to be read first, this enchanting prequel, with its story of time travel, sorcery, and magic rings, is essential reading for anyone who wants to learn the backstory to the biggest movie release of the year.

Set in the pre-Christian world of Glome on the outskirts of Greek civilization, it is a tale of two princesses: the beautiful Psyche, who is loved by the god of love himself, and Orual, Psyche's unattractive and embittered older sister, who loves Psyche with a destructive possessiveness. Her frustration and jealousy over Psyche's fate sets Orual on the troubled path of self-discovery. Lewis's last work of fiction, this is often considered his best by critics.

Christianity is the most enduring and influential legacy of the ancient world, and its emergence the single most transformative development in Western history. Even the increasing number in the West today who have abandoned the faith of their forebears, and dismiss all religion as pointless superstition, remain recognisably its heirs. Seen close up, the division between a sceptic and a believer may seem unbridgeable. Widen the focus, though, and Christianity's enduring impact upon the West can be seen in the emergence of much that has traditionally been cast as its nemesis.
