With advances in technology, from armor to in the Middle Ages to nerve gas in World War I to weapons of mass destruction in our own time, the rules have constantly evolved. Today, when killing the enemy can seem palpably risk-free and tantamount to playing a violent video game, what constitutes warfare? What is the effect of remote combat on individual soldiers? And what are the unforeseen repercussions that could affect us all?

Armored cars, burner phones, top-notch weaponry, and top-secret missions - this is the life of today's private military contractor. Like author Simon Chase, many PMCs were once the world's top military operatives, and since retiring from outfits like US Navy SEAL TEAM Six and the UK's Special Boat Service, they have devoted their lives to executing missions too sensitive for the government to acknowledge. Chase reveals here for the first time the operations too hazardous and politically volatile to be officially sanctioned by his employers.

To some, the concept of having faith in a higher power or a set of religious beliefs is nonsensical.

With conviction and clear thinking, Geisler and Turek guide listeners through some of the traditional, tested arguments for the existence of a creator God.

The secretive Mysteries conducted at Eleusis in Greece for nearly two millennia have long puzzled scholars with strange accounts of initiates experiencing otherworldly journeys. In this groundbreaking work, three experts - a mycologist, a chemist, and a historian - argue persuasively that the sacred potion given to participants in the course of the ritual contained a psychoactive entheogen. The authors then expand the discussion to show that natural psychedelic agents have been used in spiritual rituals across history and cultures.

The late Carl Rogers, founder of the humanistic psychology movement, revolutionized psychotherapy with his concept of "client-centered therapy."
