Notes
1 Lewis, The Collected Letters of C. S. Lewis, 1105.
2 Lewis, The Abolition of Man, ch. 3 n. 33.
3 Summa Theologiae, I–II, Q. 96, A. 2., quoted on p. 113. The authors disagree (p. 118 n. 45) with Adam Barkman’s conclusion based on Lewis’s unfavorable marginalia of Mill’s work that Mill was wrong “about nearly everything” (C. S. Lewis and Philosophy as a Way of Life [Allentown, PA: Zossima Press, 2009], p. 447).
4 Tolkien, The Letters of J. R. R. Tolkien, p. 61.
5 Lewis, Mere Christianity, 96 (quoted on p. 115).
6 This is not only a guiding principle of The Four Loves but the idea surfaces in many of Lewis’s writings on love, such as The Allegory of Love (Oxford University Press, 1936) p. 199, and ‘We Have No “Right to Happiness”’ (in C. S. Lewis: Essay Collection and Other Short Pieces, ed. Lesley Walmsley [London: HarperCollins, 2000], p. 391).
