The phenomenon of friendship is universal. Friends, after all, are the family we choose. But what makes these bonds not just pleasant but essential, and how do they affect our bodies and our minds? In Friendship, science journalist Lydia Denworth takes us in search of the biological, psychological, and evolutionary foundations of this important bond. She finds that the human capacity for friendship is as old as humanity itself, when tribes of people on the African savanna grew large enough for individuals to seek meaningful connection with those outside their immediate families. Lydia meets scientists at the frontiers of brain and genetics research, and discovers that friendship is reflected in our brain waves, our genomes, and our cardiovascular and immune systems; its opposite, loneliness, can kill. With insight and warmth, Lydia weaves past and present, biology and neuroscience, to show how our bodies and minds are designed for friendship, and how this is changing in the age of social media. Blending compelling science, storytelling, and a grand evolutionary perspective, she delineates the essential role that cooperation and companionship play in creating human (and non-human) societies. Friendship illuminates the vital aspects of friendship, both visible and invisible, and offers a refreshingly optimistic vision of human nature. It is a clarion call for putting positive relationships at the centre of our lives.

We all want true friends. But how many of us really know what friendship is, or where to find it? In these pages, philosopher John Cuddeback weaves together the timeless wisdom of Scripture, of the ancient Greeks, and the saints to map out the steep and beautiful path to man's greatest joy—true friendship. Following Aristotle's teachings on the unbreakable connection between happiness and virtuous living, Cuddeback sees friendship at the very center of the human drama. Although there are different kinds of friendship, the deepest kind can only be achieved through a life of virtue, and this is where the human person comes most fully alive. True Friendship offers simple yet rich advice on how to tap into this reality in our own lives. Such friendship demands much of us, but it gives us even more, as individuals and as a society. Both the Old and New Testaments place a premium on friendship. In the Christian vision, the philosophers' insights attain a broader supernatural perspective. Christ transforms human friendship and expands it. With help from the writings of Saints Thomas and Aelred, Cuddeback discovers what lies at the heart of the Christian life—the wondrous and unsurpassable reality of friendship with God in Jesus, the Divine Friend, who is at work in all our authentic friendships.

God made you for friendship. Friendship is one of the deepest pleasures of life. But in our busy, fast-paced, mobile world, we've lost this rich view of friendship and instead settled for shallow acquaintances based on little more than similar tastes or shared interests. Helping us recapture a vision of true friendship, pastor Drew Hunter explores God's design for friendship and what it really looks like in practice—giving us practical advice to cultivate the kinds of true friendships that lead to true and life-giving joy.

Friendships are like flowers. If you take care of them, they grow and bloom until you have a beautiful garden! The Little Book of Friendship shows young readers what they need to know to make a friend and to be one too.

The value of a true friend seems a unanimous declaration: a friend is “someone who knows all about you and still loves you” (Elbert Hubbard) and “the most precious of all possessions” (La Rochefoucauld); friendship is “a single soul dwelling in two bodies” (Aristotle), “the only cement that will ever hold the world together” (Woodrow Wilson). And yet, the statement that gets at the heart of Ugarte’s book Deep Friendship belongs to Plutarch, who says: “A constant friend is a thing rare and hard to find.” This is especially true in today’s world, in which we are constantly surrounded by people, but seldom experience deep friendship. The concept and value of friendship has become, more than ever, a rare treasure. What seems a simple task—that of finding a true friend who cares, respects, and deeply appreciates you—can be harder than expected. In his book, Ugarte shares not only how to find a good friend, but how to be one. These attributes of true friendship lead to great benefits, including a more genuine happiness and a greater union with God.
