"A clear and fascinating case for a broadly theistic conception of evolution that considers the “dual potential of human nature” — our propensity for both altruism and selfishness, or, put another way, good and evil — to be both a result of the way evolution shaped us and a key to what gives life meaning."

– National Review

"Wilkinson, like so many 19th- and early-20th-century philosophers and scientists, is attempting to bridge the seeming gulf between reason and faith—and he does an admirable job. Wilkinson performs a service by making them more accessible to lay readers. Wilkinson’s description of our nature deserves a hearing: In order to inspire and protect meaningful relationships, human beings have to negotiate their 'dual potentials' carefully. We don’t have to be perfect, but we do, on balance, have to make the right decisions day after day, year after year. Every world religion, every great spiritual or wisdom tradition, has this idea stitched into its moral fabric. If Wilkinson is right, it’s also part of our very flesh and blood."

– The American Scholar

"An insightful explanation of evolution and human nature in which religion is neither excluded nor central."

– Kirkus Reviews

“Wilkinson has done something extraordinary: He has provided a science-based answer to the world’s most intractable philosophical question. And he has done it in elegant, entertaining prose that any thoughtful person can enjoy. This book will change your life. It tells us not just how to live, but why. It is especially inspiring to young people struggling to find purpose in an uncertain age. This book is for anyone who wonders about the meaning of life."

– John Morley, Yale University

"Samuel Wilkinson brings his considerable expertise to questions of evolution, purpose and God. What results is an innovative approach which takes the science seriously both in what it can say and where it needs a wider context to give insights into what it means to be fully human."

– Reverend Professor David Wilkinson, Principal of St John’s College, Durham University

"In this lively, refreshing, and well-written book, Samuel Wilkinson thoughtfully explores the fascinating problems of evolution, freedom, meaning, and religion. Complex ideas are explained in simple and clear terms, and arguments on all sides are carefully scrutinized. Readers will enjoy engaging with this intelligent and humble mind. Anyone interested in the deep questions about human life will find this book a valuable and stimulating read."

"Psychiatrist Sam Wilkinson digs deeply into recent insights about how evolution has shaped the competing dispositions of human nature, and how these observations point to a Creator God who has a purpose for our existence. If you are one of many in our technological society who is troubled about whether science and faith can be harmonized, you will be reassured and inspired by this intellectually rigorous and spiritually compelling presentation.”

– Francis S. Collins, MD, PhD, Leader of the Human Genome Project, Author of The Language of God, and Founder of BioLogos

"An essential book by every measure. Beautifully written, superbly researched—and life changing. You will never think of your life, or the earth, or the purpose of each in the same way again!”

– Greg McKeown, New York Times bestselling author of Effortless and Essentialism

"If you struggle to reconcile faith and reason, Sam Wilkinson’s profound book Purpose was written for you. You will be left with an understanding of the guiding forces behind human evolution and behavior.”

– Arthur C. Brooks, Professor, Harvard Kennedy School and Harvard Business School, and #1 New York Times bestselling author

"Into the midst of the often contentious debate about evolution and the meaning of life, Purpose breathes a breath of fresh air. By taking seriously the notion that “everything that is evolved”, Wilkinson highlights how evolution must then be responsible not just for our genetic material, but also for the apparent dual nature of human nature—the tension between selfishness and altruism or between aggression and cooperation. These aspects of human nature suggest that, while the steps of evolution are random, the higher order principles that guide evolution have all the apparent hallmarks of having a clear purpose. I highly recommend this to those seeking a clear and hopeful perspective on how modern science can help us pursue a meaningful life.”
