C. S. Lewis
Mere Christianity defended by a Platonist-Realist who loved the medieval cosmos
Lewis taught medieval and Renaissance literature at Magdalen College, Oxford, and from 1954 at Magdalene College, Cambridge. His apologetic works — "Mere Christianity" (1952, from BBC broadcasts in 1941–44), "Miracles" (1947), "The Abolition of Man" (1943) — defend a generic, creedal Christian metaphysics with arguments drawn equally from common-sense realism, Aristotelian-Thomistic natural theology, and Platonic intuitions about the reality of transcendent goods. "The Discarded Image" (1964) is his clearest statement of how much he admired the medieval cosmos as a model of integrated thought, even where modern physics had left it behind.

Lewis was Anglican rather than Lutheran, but the framework groups confessional Protestant theism here. His "mere" Christianity — creation, fall, incarnation, redemption, judgement, resurrection — is the shared substance of Reformation Christianity.
"Christianity, if false, is of no importance, and if true, of infinite importance. The only thing it cannot be is moderately important." (God in the Dock, posthumous)
A pervasive Platonism: real abstract goods (Joy, Beauty, the Good itself), the soul as oriented toward what transcends the sensory, the world of becoming as a copy of a higher order. The Narnia books end with this explicitly.
"All their life in this world and all their adventures in Narnia had only been the cover and the title page: now at last they were beginning Chapter One of the Great Story which no one on earth has read." (The Last Battle, 1956)
Lewis is a common-sense realist about the external world and a moral realist about good and evil. The Abolition of Man is, among other things, a sustained defence of objective moral facts against constructivist alternatives.
"You cannot go on 'explaining away' for ever: you will find that you have explained explanation itself away. … To 'see through' all things is the same as not to see." (The Abolition of Man, 1943)
Lewis read Aquinas, Aristotle, and Boethius carefully and drew on them throughout. The natural-law argument in "The Abolition of Man" and the moral-argument-for-God in "Mere Christianity" are recognisably Thomistic in shape.
"Reason is the natural organ of truth; but imagination is the organ of meaning. … Meaning is the antecedent condition both of truth and falsehood." ("Bluspels and Flalansferes," 1939)
Internal Tensions
Lewis's Platonism and his Christian doctrine of the goodness of matter pull in opposite directions, and he never quite resolved which is in the foreground. His fiction is more Platonic (Narnia's ascent through ever-realer worlds), his apologetics more incarnational. The deeper tension is the apologist's problem: arguments from common-sense realism, from natural law, from desire, and from miracles are aimed at different audiences and rest on different starting points. Lewis ran them in parallel rather than synthesising them.
I. Time
"Both" — created time within a finite cosmos, eternity outside it. Lewis is a careful reader of Augustine and Boethius on this point. "For [God], all the physical events and all the human acts are present in an eternal Now." (Mere Christianity, Book IV) Linear within creation, non-deterministic because human freedom is real and consequential.
Attributes
II. Space
Substantival in the medieval sense — a real container — but "Both" in extent because Lewis thinks of the cosmos as bounded by a Creator who is not in it. Flat, local, three-dimensional. "The Discarded Image" describes the older spatial cosmos he loved without pretending modern physics has not displaced it.
Attributes
III. Matter
Substantival, conserved, three-dimensional, local. Lewis is no idealist about matter: in "Miracles" he argues for the resurrection of the body precisely because matter is the proper mode of created existence, not a husk to be shed.
Attributes
IV. Observer
Single embodied person, plural among others, actively engaged. Metaphysical agency: Personal — God the Trinity is the supreme Person, and human persons reflect that ground. "There are no ordinary people. You have never talked to a mere mortal." ("The Weight of Glory," 1941)
Attributes
V. Energy
Conventional: finite, conserved, irreversible. Lewis takes the second law seriously and reads its irreversibility as a sign that the natural order is not self-sufficient — it has a beginning and an end. (Mere Christianity, Book II)
Attributes
VI. Information
Conserved at both scales. The historical record, the moral law, and the soul all persist. Personal-identity conservation is doctrinal: the resurrection of the body and the life everlasting.
