Roy Sorensen here defends the causal theory of perception by treating absences as causes. He draws heavily on common sense and psychology to vindicate the assumption that we directly perceive absences.

“A luminous, moving and visual record of fleeting moments of connection.” —New York Times Book Review, Editors’ Choice A visionary work of radical empathy. Known for immersion journalism that is more immersed than most people are willing to go, and for a prose style that is somehow both fierce and soulful, Jeff Sharlet dives deep into the darkness around us and awaiting us. This work began when his father had a heart attack; two years later, Jeff, still in his forties, had a heart attack of his own. In the grip of writerly self-doubt, Jeff turned to images, taking snapshots and posting them on Instagram, writing short, true stories that bloomed into documentary. During those two years, he spent a lot of time on the road: meeting strangers working night shifts as he drove through the mountains to see his father; exploring the life and death of Charley Keunang, a once-aspiring actor shot by the police on LA’s Skid Row; documenting gay pride amidst the violent homophobia of Putin’s Russia; passing time with homeless teen addicts in Dublin; and accompanying a lonely woman, whose only friend was a houseplant, on shopping trips. Early readers have called this book “incantatory,” the voice “prophetic,” in “James Agee’s tradition of looking at the reality of American lives.” Defined by insomnia and late-night driving and the companionship of other darkness-dwellers—night bakers and last-call drinkers, frightened people and frightening people, the homeless, the lost (or merely disoriented), and other people on the margins—This Brilliant Darkness erases the boundaries between author, subject, and reader to ask: how do people live with suffering?

Christians are supposed to be “the light of the world.” Yet we seem to spend most of our time stumbling in the dark. We want answers carved in stone, and instead we get uncertainty. We want a clearly marked path and a panoramic view of the future, and God gives us only fleeting glimpses of what lies ahead—and just enough light to take the next step. So what do we do? We take the next step. In her much anticipated follow-up to Looking for God, Nancy Ortberg takes readers on a journey that began thousands of years ago. From an ancient cave in Turkey to the California coast, Nancy highlights the often unexpected, sometimes imperceptible, yet always extraordinary means God uses to light our way through even the most painful and challenging moments in life.

It seems to be common knowledge that by the time persons reach adolescence, they have been "socialized" out of much of their innate creativity. By the time we reach adulthood, many of us feel that we have no creativity at all. This book begs to differ and encourages readers to get re-acquainted with the God-given creativity that IS within.

Seeing Without Eyes is the narration of real life experiences of Joe Koury as he transitioned through sight loss and learned to "see" using echo location techniques and survival instinct. This book was written in response to the previous book titled "Flying Blind, One Man's Journey Out of Darkness" by Lou Briganti which left many readers asking for more.Many of us experience a moment in which a single event takes us in an entirely new and unanticipated direction. In such moments, we are tested, and the rest of our lives follow a far different path than the one we had planned. This is the story of Joe Koury, who, in 1954 at age 19, experienced that life altering moment when he suddenly lost his sight and started a wholly unplanned life as a blind man. It is a story of sudden desperation and a decision made in that moment that demanded much of him: courage, sacrifice, and enormous self-reliance. It is a story of one man who made an epic journey - out of darkness.
