C.S. Lewis on Love: The Philosophy Behind the Quote
Clive Staples Lewis, known to the world as C.S. Lewis, was an Oxford and Cambridge scholar whose literary and philosophical legacy extends far beyond his time. Born in 1898 in Belfast, Northern Ireland, Lewis became one of the most influential Christian apologists and fantasy authors of the twentieth century. When he wrote “Love is not affectionate feeling, but a steady wish for the loved person’s ultimate good as far as it can be obtained,” he was drawing from decades of personal struggle, intellectual rigor, and spiritual transformation. This quote comes primarily from his 1960 work “The Four Loves,” a sophisticated theological exploration of love in all its forms: affection (storge), friendship (philia), romantic love (eros), and divine love (agape). In this small but dense book, Lewis distinguished between the emotional experience of love and its deeper, more durable essence—a distinction that emerged from both his academic training in medieval philosophy and his personal journey toward Christian faith.
The context surrounding this quote reveals much about Lewis’s approach to defining love in an age increasingly governed by sentiment and subjective experience. Writing in the late 1950s, Lewis witnessed a cultural shift toward romanticizing emotion as the primary measure of genuine feeling. His quote represents a deliberate counterargument to this trend, rooted in classical and Christian traditions that understood love as something fundamentally oriented toward action and sacrifice rather than mere sensation. Lewis had spent his academic career studying medieval literature and theology, where love was consistently portrayed as a commitment transcending ephemeral feelings. His personal letters and journals show he was particularly concerned with what he saw as the modern confusion between infatuation and true love, between the pleasure of another’s company and genuine concern for their welfare. The quote emerges from this intellectual and spiritual wrestling match with contemporary culture’s treatment of one of humanity’s most significant experiences.
Lewis’s own biography adds profound texture to his understanding of love’s true nature. He experienced what many consider the defining romantic relationship of his life relatively late—at age forty-one, he married the American writer Joy Davidman Gresham, whom he had known through correspondence for years before she moved to Oxford. This marriage, which lasted only four years before Davidman’s death from cancer in 1960, profoundly shaped his thinking about love’s spiritual dimensions. During her illness, Lewis faced the terrible paradox of loving someone while being unable to prevent her suffering—a situation that demanded precisely the kind of “steady wish for the loved person’s ultimate good” he describes in the quote. He watched her endure unbearable pain with grace and witnessed his own love transform from romantic affection into something deeper and more sacrificial. The experience validated his philosophical definition while devastating him personally, creating a poignant tension between theory and lived reality. After her death, Lewis would write “A Grief Observed,” a raw and honest journal that, while grief-stricken, never contradicted his earlier assertion about love’s true nature—if anything, it confirmed it through the crucible of experience.
A lesser-known aspect of Lewis’s life is his remarkable intellectual humility and his capacity to change his mind about significant matters. Born into a Protestant family in Northern Ireland, young Lewis became an atheist during his boarding school years, a position he held with passionate conviction. His conversion to Christianity came gradually through conversations with friends, including the philosopher Tolkien, and through extensive reading—particularly the works of George MacDonald and Dante. This personal transformation from skeptic to believer wasn’t instantaneous or easy; it involved intellectual surrender that Lewis found both unwelcome and ultimately liberating. This biographical fact matters tremendously when understanding his quote about love, because Lewis approached love itself with the same hard-won honesty he brought to faith. He refused sentimentality, rejected easy answers, and insisted on empirical and logical rigor even when addressing matters of the heart. Few people realize that Lewis, who advised countless readers on matters of love and marriage through his letters and essays, initially found romantic love somewhat embarrassing and suspect. His evolution toward valuing it as a genuine path to understanding the divine represents a genuine intellectual journey, not an inherited certainty.
The philosophical roots of Lewis’s definition of love run deep into medieval and ancient Christian thought. Lewis was intimate with the distinctions made by theologians from Augustine to Aquinas, who consistently differentiated between love as feeling (what we might call subjective experience) and love as virtue (a stable disposition and commitment). When Lewis wrote that love is not affectionate feeling but a wish for the beloved’s ultimate good, he was channeling this centuries-old tradition while translating it into modern language. He was particularly influenced by medieval writers who understood love as fundamentally oriented toward the good of the other, often at cost to the self. This wasn’t original with Lewis, but his gift was making this ancient wisdom accessible to modern readers who had inherited a Romantic and increasingly therapeutic understanding of love as primarily about fulfilling the self’s emotional needs. His quote functions as a philosophical corrective, gently redirecting readers away from the trap of confusing personal happiness with the demanding reality of loving another person well. The quote’s power derives partly from this countercultural stance—it offers readers permission to recognize that genuine love sometimes involves difficulty, sacrifice, and acting against our momentary feelings.
The cultural impact of Lewis’s formulation of love has been significant, though often working beneath the surface of popular discourse. His book “The Four Loves” became essential reading for marriage counselors, clergy, educators, and anyone seeking to understand the different dimensions of human connection.
