Attacking the notion of morality as nothing more than institutionalised weakness, Nietzsche criticises past philosophers for their unquestioning acceptance of moral precepts. Nietzsche tried to formulate what he called "the philosophy of the future".

The Republic poses questions that endure: What is justice? What form of community fosters the best possible life for human beings? What is the nature and destiny of the soul? What form of education provides the best leaders for a good republic? What are the various forms of poetry and the other arts, and which ones should be fostered and which ones should be discouraged? How does knowing differ from believing?

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.

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.

Towards the end of his life, Seneca the Younger (c4 BCE-65 CE) began a correspondence with a friend in Sicily, later collected under the title The Moral Epistles. In these 124 letters, Seneca expresses, in a wise, steady and calm manner, the philosophy by which he lived - derived essentially from the Stoics. The letters deal with a variety of specific topics - often eminently practical - such as 'On Saving Time', 'On the Terrors of Death', 'On True and False Friendships', 'On Brawn and Brains' and 'On Old Age and Death'.

We see, as they perhaps do not, that to many of them, this series of lessons will be as seed planted in fertile soil - which will in due time put forth sprouts, which will force their way gradually into the sunlight of consciousness where they will put forth leaves, blossom and fruit. Many of the fragments of truth which will be presented to you will not be recognized by you at this time; but in years to come, you will recognize the verity of the impressions which will be conveyed to you in these lessons.

This is a beautiful description of Helen Keller's discoveries as she learns to appreciate, through the sense of touch, the world around her. Loss of sight and hearing only increase her joy of life and its treasures.

The Kybalion has long fascinated readers and listeners with its exploration of hermetic wisdom.

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.

Ralph Waldo Emerson's "Nature" is perhaps the greatest original work of philosophy written by an American. This specially-prepared edition includes a foreword on the origin and significance the book.

Here in one volume are both the Essays: First Series and Essays: Second Series from one of the most influential philosophers in American history. Although Ralph Waldo Emerson, perhaps America’s most famous philosopher, did not wish to be referred to as a transcendentalist, he is nevertheless considered the founder of this major movement of nineteenth-century American thought. Emerson was influenced by a liberal religious training; theological study; personal contact with the Romanticists Coleridge, Carlyle, and Wordsworth; and a strong indigenous sense of individualism and self-reliance.

Published to great acclaim in 1873, Walter Pater’s compendium of idiosyncratic, impressionistic essays on the Renaissance gained him a reputation as a daring modern philosopher. Oscar Wilde called it the “holy writ of beauty.” It was Pater’s cry of “art for art’s sake” that became the manifesto for the aesthetic movement. He believed that art should be sensual and that beauty should rank as the highest ideal. Marked by elegant fluency, Pater’s essays discuss Botticelli, Michelangelo, Leonardo da Vinci, and other artists who, for him, embodied the spirit of the Renaissance.

Phaedrus lures Socrates outside the walls of Athens, where he seldom goes, by promising to share a new work by his friend and mentor, Lysias, a famous writer of speeches. This dialogue provides a powerful example of the dialectical writing that Plato uses to manifest ideas that are essential to human existence and to living a good life. Phaedrus shows how oral and written forms of language relate to each other and to philosophy.

This famous work by Lucretius is a masterpiece of didactic poetry, and it still stands today as the finest exposition of Epicurean philosophy ever written. The poem was produced in the middle of first century B.C., a period that was to witness a flowering of Latin literature unequaled for beauty and intellectual power in subsequent ages. The Latin title, De Rerum Natura, translates literally to On the Nature of Things and is meant to impress the reader with the breadth and depth of Epicurean philosophy.

The Gay Science (The Joyful Wisdom) is one of Nietzsche's greatest books. His wonderfully fertile mind roams over mankind, his thoughts, his emotions, his behaviour and his weaknesses with remarkable clarity, with insight - but also with humour!In this work are 383 separate paragraphs, some short, some long, but all singular observations - the epitome of his famous aphoristic style. 'Morality is the herd instinct in the individual.'

The Discarded Image paints a lucid picture of the medieval worldview, providing the historical and cultural background to the literature of the middle ages and renaissance. It describes the 'image' discarded by later years as "the medieval synthesis itself, the whole organization of their theology, science, and history into a single, complex, harmonious mental model of the universe". This, Lewis' last book, has been hailed as "the final memorial to the work of a great scholar and teacher and a wise and noble mind".

Charged with treason under Theodoric the Great in sixth-century Rome, Boethius served one year's imprisonment, awaiting trial and eventual execution. During this time, he wrote The Consolation of Philosophy, which would go on to be one of the most popular philosophical works of all time, contributing much to medieval thought and influencing the likes of Dante and Chaucer, as well as Renaissance writers, such as Milton and Shakespeare.

The Varieties of Religious Experience is considered to be the classic work in the field. To quote Wikipedia, "James was most interested in understanding personal religious experience. The importance of James to the psychology of religion - and to psychology more generally - is difficult to overstate. He discussed many essential issues that remain of vital concern today. What makes James writing so special is that he could take a very complex subject and, without watering it down, make it understandable to 'the rest of us.'"

Edward Bulwer-Lytton's book is ostensibly a work of Science Fiction. It deals with an underground race of advanced beings, masters of Vril energy - a strange power that can both heal and destroy - who intend to leave their subterranean existence and conquer the world. But the book has been seen by many as a barely concealed account of Hidden Wisdom, a theory that has attracted many strange bed-fellows, including the French author Louis Jacolliot, the Polish explorer Ferdinand Ossendowsky, and Adolf Hitler.
