Throughout history society has determined specific rules of engagement between adversaries in armed conflict. 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?

More than 2,000 years after his death, Julius Caesar remains one of the great figures of history. He shaped Rome for generations, and his name became a synonym for "emperor" - not only in Rome but as far away as Germany and Russia. He is best known as the general who defeated the Gauls and doubled the size of Rome's territories. But, as Philip Freeman describes in this fascinating new biography, Caesar was also a brilliant orator, an accomplished writer, a skilled politician, and much more.

On the night of January 30, 1933, Adolf Hitler leaned out of a spotlit window of the Reich chancellery in Berlin, bursting with joy. The moment seemed unbelievable, even to Hitler. After an improbable political journey that came close to faltering on many occasions, his march to power had finally succeeded. While the path of Hitler's rise has been told in books covering larger portions of his life, no previous work has focused solely on his eight-year climb to rule: 1925-1933.

By 100 years ago, it seemed clear that the speed of light was the fastest possible speed. Causality was safe. And then quantum mechanics happened, introducing spooky connections that seemed to circumvent the law of cause and effect. From Aristotle's Physics to quantum teleportation, learn about the scientific pursuit of instantaneous connections in this insightful examination of our world.

Is good character something that can be taught? In 430 BCE, Socrates set out to teach the vain, power-seeking Athenian statesman Alcibiades how to be a good person—and failed spectacularly. Alcibiades went on to beguile his city into a hopeless war with Syracuse, and all of Athens paid the price. In The Quest for Character, philosophy professor Massimo Pigliucci tells this famous story and asks what we can learn from it.

The Pity of War makes a simple and provocative argument: the human atrocity known as the Great War was entirely England's fault. According to Niall Ferguson, England entered into war based on naive assumptions of German aims, thereby transforming a Continental conflict into a world war, which it then badly mishandled, necessitating American involvement. The war was not inevitable, Ferguson argues, but rather was the result of the mistaken decisions of individuals who would later claim to have been in the grip of huge impersonal forces.

In spring 2011, Syrian President Bashar al-Assad turned to his friend and army commander, Manaf Tlass, for advice about how to respond to Arab Spring-inspired protests. Tlass pushed for conciliation but Assad decided to crush the uprising - an act which would catapult the country into an eight-year long war, killing almost half a million and fueling terrorism and a global refugee crisis. Assad or We Burn the Country examines Syria's tragedy through the generational saga of the Assad and Tlass families, once deeply intertwined and now estranged....

Founded in London in 1717 as a way of binding men in fellowship, Freemasonry proved so addictive that within two decades it had spread across the globe. Masonic influence became pervasive. Under George Washington, the Craft became a creed for the new American nation. Masonic networks held the British empire together. Under Napoleon, the Craft became a tool of authoritarianism and then a cover for revolutionary conspiracy. Both the Mormon Church and the Sicilian mafia owe their origins to Freemasonry.

The definitive history of a powerful family dynasty who dominated Europe for centuries - from their rise to power to their eventual downfall.

In Alexander the Great, Anthony Everitt judges Alexander’s life against the criteria of his own age and considers all his contradictions. We meet the Macedonian prince who was naturally inquisitive and fascinated by science and exploration, as well as the man who enjoyed the arts and used Homer’s great epic, the Iliad, as a bible. As his empire grew, Alexander exhibited respect for the traditions of his new subjects and careful judgment in administering rule over his vast territory. But his career also had a dark side.

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.

With the end of the Civil War, the nation recommenced its expansion onto traditional Indian tribal lands, setting off a wide-ranging conflict that would last more than three decades. In an exploration of the wars and negotiations that destroyed tribal ways of life even as they made possible the emergence of the modern United States, Peter Cozzens gives us both sides in comprehensive and singularly intimate detail.

Amid the ravages of economic depression, Germans in the early 1930s were pulled to political extremes both left and right. Then, in the spring of 1933, Germany turned itself inside out, from a deeply divided republic into a one-party dictatorship. In Hitler's First Hundred Days, award-winning historian Peter Fritzsche offers a probing account of the pivotal moments when the majority of Germans seemed, all at once, to join the Nazis to construct the Third Reich.
