Logic for the Sake of Love

  • Oct 19, 2010
What is the relationship between logic and love?

For some, there is no relation. "Love Is a Fallacy" by Max Shulman tells the story of a smart college freshman who pines for Polly Espy, the girlfriend of his big-man-on-campus roommate, Petey Bellows. Petey, however, pines for a raccoon coat, which is all the rage among BMOCs. In exchange for a chance to date Polly, the freshman gives Petey his father's raccoon coat.

Unfortunately, Polly's intelligence does not match her beauty, so the freshman sets out to school her, beginning with logical fallacies. Patiently he teaches her the fallacies of hasty generalization, post hoc, ad misericordiam, and poisoning the well, among others. After five dates, satisfied that she has risen to a level of intelligence acceptable to him, the freshman declares his love for her.

She then proceeds to point out the logical fallacies inherent in each of his arguments in favor of the match and instead declares her love for...Petey Bellows. "Can you give me one logical reason why you should go steady with Petey Bellows?" he screams. "I certainly can," she replies. "He's got a raccoon coat."

To quote Blaise Pascal: "The heart has its reasons which reason knows nothing of."

In Think, John Piper begs to differ with people who see no relationship between logic and love. There is a relationship between the two, a mutually enriching one at that. "The fires of love for God need fuel. And the fires of love for God drive the engines of thought and deed. There is a circle. Thinking feeds the fire, and the fire fuels more thinking and doing. I love God because I know him. And I want to know him more because I love him" (89). This mutually enriching relationship encompasses our love for people as well. Indeed, "All scholarship is for the love of God and man" (167).

For me, the most insightful sections of the book were "Coming to Faith through Thinking" (58-82), "Facing the Challenge of Relativism" (94-118), and "Facing the Challenge of Anti-intellectualism" (118-156).

"Coming to Faith through Thinking" shows that reasoning plays a role in conversion and clarifies how. The two chapters in this section effectively rebut the popular evangelical sentiment that you cannot argue a person into the kingdom of God. True, conversion encompasses more than thinking, but never less.

"Facing the Challenge of Relativism" lays bare the immorality and incoherence of relativism using a dialogue about religious authority between Jesus and the Pharisees (Matthew 21:23-27). The Pharisees asked Jesus, "By what authority are you doing these things?" In response, Jesus asked, "John's baptism--where did it come from? Was it from heaven, or from men?" The Pharisees realized that either answer would get them into trouble, so they demurred. Piper comments: "People don't embrace relativism because it is philosophically satisfying. They embrace it because it is physically and emotionally gratifying. It provides the cover they need at key moments in their lives to do what they want without intrusion from absolutes." It is immoral, in other words. It is incoherent because "no one is a relativist" at the bank" (102).

"Facing the Challenge of Anti-intellectualism" examines six spiritual reasons people give for anti-intellectualism. Two of these reasons arise from misinterpretations of biblical passages, namely, Luke 10:17-24 and 1 Corinthians 1:20-24. The former states, "You [God] have hidden these things from the wise and understanding." The latter, "In the wisdom of God, the world did not know God through wisdom." Piper carefully exegetes these passages and concludes: "the warnings that Jesus and Paul have sounded...are not warnings about careful, faithful, rigorous, coherent thinking in the pursuit of God. In fact, the way Jesus and Paul spoke these very warnings compels us to engage in serious thinking even to understand them. And what we find is that pride is no respecter of persons--the serious thinkers may be humble. And the careless mystic may be arrogant" (154).

Historian Mark Noll once wrote, "The scandal of the evangelical mind is that there is not much of an evangelical mind." Unfortunately, this is all too often true. The strength of Think by John Piper is his patient exposition of the Bible, which critiques evangelical mindlessness and points to the twin imperatives of the Great Commandment: "Love the Lord your God with all your heart and with all your soul and with all your mind" and "Love your neighbor as yourself" (Matthew 22:38-39).

About this book


"Piper has done it again. His outstanding book Think promises to shepherd a generation about the Christian commitment to the life of the mind. Deeply biblical and uniquely balanced, Think practices what it preaches: it is an accessible, intellectually rich study that calls the reader to renewed love for God and others."
-J. P. Moreland, Distinguished Professor of Philosophy, Talbot School of Theology, Biola University

"John Piper offers much wise advice on the importance of Christian thinking as a way of loving God with our minds and as part of delighting in God above all things."
-George M. Marsden, Francis A. McAnaney Professor of History, University of Notre Dame; author, Jonathan Edwards: A Life

"Do you ever wish you could feel more deeply about things you know are true? Has it been a while since you were moved to tears at the thought of Christ-s death for your sins? It-s not mysterious: those who feel deeply about the gospel are those who think deeply about the gospel. In these pages John Piper will convince you that thinking is the sturdy foundation for our easily misguided affections. If you want to feel profoundly, learn to think carefully. And start by reading this book!"
