The Root of Friendship addresses the connections between self-love and self-governance in the thought of St. Thomas Aquinas and defends three related theses. First, Aquinas's account of proper self-love is a description of the nature and importance of a person's subjective self- experience. Second, his notion of self-governance cannot be understood fully unless we grasp its basis in self-love. Finally, his account both satisfies contemporary conditions of relevance for self-governance and offers attractive solutions to issues raised in analytic discussions on such matters.

Trees seen like never before—a world expert presents a stunning compendium, illuminating science, conservation, and art. 

Trees provoke deep affection, spirituality, and creativity. They cover about a third of the world’s land and play a crucial role in our environmental systems—influencing the water, carbon, and nutrient cycles and the global climate. This puts trees at the forefront of research into mitigating our climate emergency; we cannot understate their importance in shaping our daily lives and our planet’s future. 

In these lavish pages, ecologist Paul Smith celebrates all that trees have inspired across nearly every human culture throughout history. Generously illustrated with over 450 images and organized according to tree life cycle—from seeds and leaves to wood, flowers, and fruit—this book celebrates the great diversity and beauty of the 60,000 tree species that inhabit our planet. Surprising photography and infographics will inspire readers, illustrating intricate bark and leaf patterns, intertwined ecosystems, colorful flower displays, archaic wooden wheels, and timber houses. In this lavishly illustrated book, Smith presents the science, art, and culture of trees. As we discover the fundamental and fragile nature of trees and their interdependence, we more deeply understand the forest without losing sight of the magnificent trees.
