'The two foes of human happiness are pain and boredom.' Arthur Schopenhauer (1788-1860) was one of the most influential philosophers of the 19th century because his humanistic, atheistic, if pessimistic views chimed with a new secularism that was emerging from a Western society dominated by religion. Despite his rather forbidding image (and a few outdated views), he is one of the most approachable German philosophers, and this is certainly evident in these two key works, The Wisdom of Life and Counsels and Maxims.

Parerga means 'supplementary to a main work', and Paralipomena suggests a further supplement, but these two books were anything but a casual addition to his major opus, The World as Will and Idea. For a start, it was the publication of Parerga and Paralipomena in 1851 which brought Schopenhauer to the attention of the general public, decades after The World as Will and Idea first appeared.

There is a cause, or a reason, behind everything that happens. This is the fundamental view behind the classical proposition the Principle of Sufficient Reason, which, in 1813, Schopenhauer chose as his subject for further examination in his doctoral dissertation On the Fourfold Root of the Principle of Sufficient Reason....

Schopenhauer was just 30 when his magnum opus, Die Welt als Wille und Vorstellung, a work of considerable learning and innovation of thought, first appeared in 1818.

Much to his chagrin and puzzlement (so convinced was he of its merits), it didn't have an immediate effect on European philosophy, views and culture. It was only decades later that it was recognised as one of the major intellectual landmarks of the 19th century.

"The Art of Controversy or The Art of Being Right" is an acidulous, sarcastic treatise written by the German philosopher Arthur Schopenhauer. In it, Schopenhauer examines a total of thirty-eight methods of showing up one's opponent in a debate. He introduces his essay with the idea that philosophers have concentrated in ample measure on the rules of logic, but have not engaged with the darker art of the dialectic, of controversy.

For thousands of years, Homer's ancient epic poem the

Iliad has enchanted readers from around the world. When you join Professor Vandiver for this lecture series on the Iliad, you'll come to understand what has enthralled and gripped so many people. Her compelling 12-lecture look at this literary masterpiece -whether it's the work of many authors or the "vision" of a single blind poet - makes it vividly clear why, after almost 3,000 years, the

Iliad remains not only among the greatest adventure stories ever told but also one of the most compelling meditations on the human condition ever written.

From his 1935 debut with "The Universal History of Iniquity", through his immensely influential collections Ficciones and The Aleph, these enigmatic, elaborate, imaginative inventions display Borges' talent for turning fiction on its head by playing with form and genre and toying with language.

One of the undisputed giants in the history of human thought, and the founder of one of the world's longest-lasting cultural traditions, Confucius (known as Kong Fuzi in his native China) is arguably the most enduring of all the world's great thinkers. The Analects, the slender volume thought to have been compiled by his followers, has the strongest claim to represent Confucius' actual words. The book contains memorable sayings about the moral health of the individual, the family and the body politic.

Charming, vibrant, witty and edifying, The Life of Samuel Johnson is a work of great obsession and boundless reverence. The literary critic Samuel Johnson was 54 when he first encountered Boswell; the friendship that developed spawned one of the greatest biographies in the history of world literature. The book is full of humorous anecdote and rich characterization, and paints a vivid picture of 18th-century London, peopled by prominent personalities of the time.

The Consolation of Philosophy is one of the key works in the rich tradition of Western philosophy, partly because of the circumstances in which it was written. Anicius Manlius Severinus Boethius (c480-c524) was of aristocratic Roman birth and became consul and then master of offices at Ravenna, one of the highest posts under the Ostrogothic Roman ruler Theodoric. But Boethius was unjustly charged with treason in 524, and this led to house arrest, then torture and execution.

Not only can we not currently explain the origin of the universe, it is questionable we will ever be able to explain it. The notion that there are universes within particles, or that particles are conscious, is ascientific, as is the hypothesis that our universe is a computer simulation. On the other hand, the idea that the universe itself is conscious is difficult to rule out entirely.

In the small coastal city of Oran, Algeria, rats begin rising up from the filth, only to die as bloody heaps in the streets. Shortly after, an outbreak of the bubonic plague erupts and envelops the human population. Albert Camus' The Plague is a brilliant and haunting rendering of human perseverance and futility in the face of a relentless terror born of nature.

The Vision of the Anointed is a devastating critique of the mindset behind the failed social policies of the past thirty years. Thomas Sowell sees what has happened not as a series of isolated mistakes, but as a logical consequence of a vision whose defects have led to disasters in education, crime, family disintegration, and other social pathology. In this book, "politically correct" theory is repeatedly confronted with facts-and sharp contradictions between the two are explained in terms of a whole set of self-congratulatory assumptions held by political and intellectual elites.

One of Nietzsche’s earliest works, The Birth of Tragedy (1872) is a remarkable source of inspiration. It is here that the philosopher expresses his frustration with the contemporary world and urges man to embrace Dionysian energy once more. He refutes European culture since the time of Socrates, arguing that it is one-sidedly Apollonian and prevents man from living in optimistic harmony with the sufferings of life.

At the heart of this classic, seminal book is Julian Jaynes' still-controversial thesis that human consciousness did not begin far back in animal evolution but instead is a learned process that came about only 3,000 years ago and is still developing. The implications of this revolutionary scientific paradigm extend into virtually every aspect of our psychology, our history and culture, our religion - and indeed our future.
