Dirt: The Ecstatic Skin of the Earth by William Bryant Logan is an enlightening and heartening read for anyone who studies the earth in science or daily living. Although a few of the factoids are not quite correct (watch that logarithmic scale!), this book is full of fascinating science of the soil, surrounded by heartfelt prose. Logan makes earth-centered philosophy accessible to anyone who has ever had a gut feeling that the land is good. The religion of the soil he presents is unobtrusive, yet all-pervading. Read it and feel good.
