Description

In What is Friendship? Conversations with the Great Philosophers, Stephen J. Costello offers a brilliant, expansive, and deeply accessible treatise on one of the most vital yet frequently misunderstood aspects of the human experience. Costello guides readers through an intellectual history of companionship, structuring the book as an ongoing conceptual dialogue with the most profound minds across Western philosophy. Moving seamlessly through time, the text examines Aristotle’s foundational classifications of friendship—based on utility, pleasure, and virtue—before diving into the theological adaptations of Thomas Aquinas, the psychological musings of Montaigne, and the rigorous ethical frameworks of Immanuel Kant, Friedrich Nietzsche, and Ralph Waldo Emerson. Far from being a dry academic exercise, the book actively applies these classical frameworks to the contemporary world, interrogating what friendship truly means in an age dominated by digital connections, social media algorithms, and superficial networking. Costello challenges readers to reconsider the moral, emotional, and spiritual obligations of a true friend, making this volume an indispensable read for anyone seeking a deeper, more structured understanding of human relationships and philosophical ethics.
