You might think laziness, lack of willpower, and/or low motivation are to blame for the fact that you aren't achieving your goals. But fascinating research in the field of psychoneuroimmunology has revealed another, far more likely possibility. One with the potential to transform your life in a dramatic way.

Man is born free, and everywhere he is in chains. In The Social Contract, Rousseau explores the concept of freedom and the political structures that may enable people to acquire it. He argues that the sovereign power of a state lies not in any one ruler but in the will of the general population. Rousseau argues that the ideal state would be a direct democracy where executive decision making is carried out by citizens who meet in assembly, as they would in the ancient city-state of Athens.

‘It was a sweet finish after the bitter pills of floggings and bullets with which these same governments, just at that time, dosed the German working-class risings’. The Communist Manifesto is, perhaps surprisingly, a most engaging and accessible work, containing even the odd shaft of humour in this translation by Samuel Moore for the 1888 English edition.

Governments today in both Europe and the United States have succeeded in casting government spending as reckless wastefulness that has made the economy worse. In contrast, they have advanced a policy of draconian budget cuts - austerity - to solve the financial crisis. We are told that we have all lived beyond our means and now need to tighten our belts. This view conveniently forgets where all that debt came from. Not from an orgy of government spending, but as the direct result of bailing out, recapitalizing, and adding liquidity to the broken banking system.

The Book of the Courtier remains the definitive account of Renaissance court life. Because of this, it is considered one of the most important Renaissance works. The book is organized as a series of fictional conversations that occur between the courtiers of the Duke of Urbino in 1507 (when Baldassare was in fact part of the Duke's Court). In the book, the courtier is described as having a cool mind, a good voice (with beautiful, elegant and brave words) along with proper bearing and gestures.

Some 250 years after its first publication, Gibbon's Decline and Fall is still regarded as one of the greatest histories in Western literature. He reports on more than 1,000 years of an empire which extended from the most northern and western parts of Europe to deep into Asia and Africa and covers not only events but also the cultural and religious developments that effected change during that time.

The leviathan is the vast unity of the State. But how are unity, peace, and security to be attained? Hobbes’ answer is sovereignty, but the resurgence of interest today in Leviathan is due less to its answers than its methods: Hobbes sees politics as a science capable of the same axiomatic approach as geometry.

Think you can’t get conned? Think again. The New York Times best-selling author of Mastermind: How to Think Like Sherlock Holmes explains how to spot the con before they spot you. A compelling investigation into the minds, motives, and methods of con artists - and the people who fall for their cons over and over again. From multimillion-dollar Ponzi schemes to small-time frauds, Konnikova pulls together a selection of fascinating stories to demonstrate what all cons share in common, drawing on scientific, dramatic, and psychological perspectives.

It is the year 778. The mighty French army, led by Emperor Charlemagne, confronts Saracen forces in the bloody Battle of Roncevaux Pass. In the course of this thrilling epic poem we follow the emperor’s hot-headed nephew Roland into battle. We are privy to the deal struck between the Saracen king Marsilie and Roland’s conniving stepfather Guene.

Immanuel Kant’s Critique of Pure Reason can lay claim to being the most important single work of modern philosophy, a work whose methodology, if not necessarily always its conclusions, has had a profound influence on almost all subsequent philosophical discourse. In this work Kant addresses, in a groundbreaking elucidation of the nature of reason, the age-old question of philosophy: “How do we know what we know?” and the limits of what it is that we can know with certainty.

A classic work of military strategy, On War sets forth the theories and tactics of Carl von Clausewitz, a distinguished Prussian general who was notable for his roles in the French Revolutionary and Napoleonic Wars. The book covers a broad range of topics, including weapons, terrain, troops, and leadership, as well as the importance of defense over offence, the balance of power, and the subordination of war to politics. Praised for its timeless insights, Clausewitz’s treatise is often compared to the work of Machiavelli and Sun Tzu, and remains relevant to military leaders.

How to Win an Election is an ancient Roman guide for campaigning that is as up-to-date as tomorrow's headlines. In 64 BC when idealist Marcus Cicero, Rome's greatest orator, ran for consul (the highest office in the Republic), his practical brother Quintus decided he needed some no-nonsense advice on running a successful campaign.

This version of Nature is an 1843 revision to the popular essay written and published in 1836. In the original essay, Emerson put forth the foundation of transcendentalism and suggested that reality can be understood by studying nature. Within the essay, Emerson divides nature into four usages: commodity, beauty, language and discipline. These distinctions define how humans use nature for their basic needs, their desire for delight, their communication with one another, and their understanding of the world.

From the perspective of an unbeliever, Fear and Trembling explores the paradox of faith, the nature of Christianity, and the complexity of human emotion. Kierkegaard examines the biblical story of Abraham, who was instructed to sacrifice his son Isaac, and forces us to consider Abraham's state of mind. What drove Abraham, and what made him carry out such an absurd and extreme request from God? Kierkegaard argues that Abraham's agreement to sacrifice Isaac, and his suspension of reason, elevated him to the highest level of faith.

James Romm seamlessly weaves together the life and written words, the moral struggles, political intrigue, and bloody vengeance that enmeshed Seneca the Younger in the twisted imperial family and the perverse, paranoid regime of Emperor Nero, despot and madman.

The Prince is a 16th-century political treatise by the Italian diplomat and political theorist Niccolò Machiavelli. Machiavelli wrote The Prince in 1513, after he was forced to leave Florence as a political exile. Dedicated to Lorenzo de’ Medici, the work is Machiavelli’s advice to the ruler of Florence on how to stay in power.

From his perspective in Renaissance Italy, Machiavelli's aim in this classic work was to resolve conflict with the ruling prince, Lorenzo de Medici. Machiavelli based his insights on the way people really are rather than an ideal of how they should be. This is the world's most famous master plan for seizing and holding power. Astonishing in its candor The Prince even today remains a disturbingly realistic and prophetic work on what it takes to be a prince, a king, or a president.

Many of the world's leaders have turned to Niccolo Machiavelli's The Art of War as a guide to the fundamentals of war, including Frederick the Great, Napoleon, as well as countless other military leaders. Limited warfare is one of the philosophies promoted in this work. Machiavelli believed that military conflict should be a last resort and should only be considered when diplomacy fails. He was also of the belief that society could only remain stable and secure with a strong state military.

A bloody revolt by a North African prince and a plot to seize control of Rome are the subjects of two short masterpieces of ancient history by the illustrious Roman chronicler, Sallust. He could not have chosen two more dramatic episodes in the long history of this city.

The rivalry between two of the dominant city states of Ancient Greece, Athens and Sparta, erupted into a war lasting nearly 30 years and was to have a dramatic effect on the balance of power in the area. Between 431 and 404 BCE, the two cities battled it out on land and sea, aided by their alliances with neighbouring states: Athens’ Delian League vigorously opposed Sparta’s Peloponnesian League in a conflict which effectively involved the whole region.

The Goths are the most enigmatic of all the ancient German tribes. Their name today is still widely in use for a variety of cultural and artistic movements. But unlike other famous German tribes whose names are still descriptive of nations they founded - the Franks, the Lombards, the Angles, the Saxons and the Alemanni - the Goths simply disappeared. The subject of Henry Bradley's splendid short history is tracing the rise, the migrations, and the impact of the Goths on European history along with their spectacular fall.

The Art of War, The Prince, and The Book of Five Rings are three historical pieces that deal with strategy. The Art of War is an ancient Chinese military treatise, and each chapter within the treatise is devoted to a distinct aspect of warfare and how that applies to military strategy and tactics. The Prince is a practical guide for ruling an empire. The Book of Five Rings is a Japanese text that has been regarded as a treatise on the strategy for winning.

Scipio Africanus (236-183 BC) was one of the most exciting and dynamic leaders in history. As commander, he never lost a battle. Yet it is his adversary, Hannibal, who has lived on in public memory. As B. H. Liddell Hart writes, "Scipio's battles are richer in stratagems and ruses - many still feasible today - than those of any other commander in history." Any military enthusiast or historian will find this to be an absorbing, gripping portrait.

In Empires of Trust, Professor Thomas F. Madden explores surprising parallels between the Roman and American republics. By making friends of enemies and demonstrating a commitment to fairness, the two republics - both "reluctant" yet unquestioned super-powers - built empires based on trust. Madden also includes vital lessons from the Roman Republic's 100-year struggle with "terrorism."

In the most definitive account to date, respected historian Charles Esdaile argues that the chief motivating factor for Napoleon was his insatiable desire for fame. More than a myth-busting portrait of Napoleon, however, this volume offers a panoramic view of the armed conflicts that spread so quickly out of revolutionary France to countries as remote as Sweden and Egypt.

For over 20 years, a select group of Yale undergraduates has been admitted into the year-long "Grand Strategy" seminar team-taught by John Lewis Gaddis and Paul Kennedy. Its purpose: to provide a grounding in strategic decision-making in the face of crisis to prepare future American leaders for important work. Now, John Lewis Gaddis has transposed the experience of that course into a wonderfully succinct, lucid and inspirational book, a view from the commanding heights of statesmanship across the landscape of world history from the ancient Greeks to Lincoln, and beyond.

The startling truth behind one of the most notorious dynasties in history is revealed in a remarkable new account by the acclaimed author of The Tudors and A World Undone. Sweeping aside the gossip, slander, and distortion that have shrouded the Borgias for centuries, G. J. Meyer offers an unprecedented portrait of the infamous Renaissance family and their storied milieu.

Ferdinand Lot (1866-1952) was one of the great historians of his generation, and the transition from Roman to Medieval civilization was a process that fascinated him most of his life. Rather than placing the emphasis for Rome’s fall on purely political or military reasons, Lot put forth multiple explanations for the birth of the Middle Ages which embrace not only politics and war, but linguistic, geographic, cultural, social and economic factors.

Initially, the Thirty Years War was precipitated in 1618 by religious conflicts between Protestants and Catholics in the Holy Roman Empire. But the conflict soon spread beyond religion to encompass the internal politics and balance of power within the Empire, and then later to the other European powers. By the end, it became simply a dynastic struggle between Bourbon France and Habsburg Spain. And almost all of it was fought out in Germany. Entire regions were depopulated and destroyed.

Plutarch (c. AD 46-AD 120) was born to a prominent family in the small Greek town of Chaeronea, about 20 miles east of Delphi in the region known as Boeotia. His best known work is the Parallel Lives, a series of biographies of famous Greeks and Romans, arranged in pairs to illuminate their common moral virtues and vices. The surviving lives contain 23 pairs, each with one Greek life and one Roman life as well as four unpaired single lives.
