The restless heart and searching mind of this influential early church father can offer spiritual and intellectual companionship for your spiritual journey. Augustine of Hippo (354–430), theologian, priest, and bishop, is one of the most important figures in the development of Western Christianity. He is known as much for his long interior struggle that ended with conversion and baptism at age thirty-two as for his influential teachings on human will, original sin and the theology of just war. Cherished as a model for the pursuit of a life of spiritual grace and criticized for his theory of predestination, Augustine is recognized as a living expression of the passion to understand and communicate the deeper meanings of human experience. With fresh translations drawn from Augustine's voluminous writings and probing facing-page commentary, Augustinian scholar Joseph T. Kelley, PhD, provides insight into the mind and heart of this foundational Christian figure. Kelley illustrates how Augustine’s keen intellect, rhetorical skill and passionate faith reshaped the theological language and dogmatic debates of early Christianity. He explores the stormy religious arguments and political upheavals of the fifth century, Augustine’s controversial teachings on predestination, sexuality and marriage, and the deep undercurrents of Augustine’s spiritual quest that still inspire Christians today.

At first glance, the beach may appear to be an endless, flat, monotone landscape meant only for swimming, snoozing, or working on your tan. Upon closer inspection, though, the beach reveals that it has myriad treasures for the curious to locate, such as ephemeral beach ripples decorating the sand, traces of miniature organisms inscribed on dunes, and armored mudballs. Atlantic Coast beaches, from Maine to Florida, are full of amazing features formed by the interactions between tides, currents, bedrock, weather, beach critters, and much more. Written for a general audience, Atlantic Coast Beaches: A Guide to Ripples, Dunes, and Other Natural Features of the Seashore covers everything, from microscopic nematodes to the potentially cataclysmic changes occurring along the coastline due to rising sea level. Its clear writing, illustrative photographs, and instructive diagrams answer some curious questions, such as why do some sands bark and sing, how do miniature sand volcanoes form, and how do barrier islands migrate?

Take this book to the beach; it will open up a whole new world. Illustrated throughout with color photographs, maps, and graphics, it explores one of the planet's most dynamic environments - from tourist beaches to Arctic beaches strewn with ice chunks to steaming hot tropical shores. "The World's Beaches" tells how beaches work, explains why they vary so much, and shows how dramatic changes can occur on them in a matter of hours. It discusses tides, waves, and wind; the patterns of dunes, washover fans, and wrack lines; and the shape of berms, bars, shell lags, cusps, ripples, and blisters. What is the world's longest beach? Why do some beaches sing when you walk on them? Why do some have dark rings on their surface and tiny holes scattered far and wide? This fascinating, comprehensive guide also considers the future of beaches, and explains how extensively people have affected them - from coastal engineering to pollution, oil spills, and rising sea levels.
