Benedict de Spinoza's Ethics, first published in 1677, constitutes a major systematic critique of the traditional and religious foundations of philosophical thought. In it, Spinoza follows a logical step-by-step format consisting of definitions, axioms, propositions, proofs, and corollaries to create a comprehensive inquiry into the truth about God, nature, and humans' place within the universe. From these broad metaphysical themes, Spinoza derives what he considered to be the highest principles of religion and society and lays out an ethical system in which reason is the supreme value.

Before his death in 1645, the undefeated swordsman Miyamoto Musashi retired to live as a hermit in a cave. There, he wrote five scrolls containing the «true principles» necessary for victory, both in martial arts and on the battlefield. Based on his experience, observation, and reasoning, Musashi describes the tactics that allowed him to remain undefeated. Published as The Book of Five Rings, this text has not only captivated the martial arts world but has also gained international recognition in the business field as a key tool for resolving conflicts and achieving success.

The Conquest of Happiness (1930) is Bertrand Russell’s short, practical guide to living more happily in the modern world. Russell argues that much unhappiness comes from patterns of thought and social pressures—like envy, fear of opinion, boredom, and the obsessive pursuit of status—and that these can be unlearned.

Born a slave, the Roman Stoic philosopher Epictetus (c. 55-135 AD) taught that mental freedom is supreme, since it can liberate one anywhere, even in a prison. In How to Be Free, A. A. Long - one of the world's leading authorities on Stoicism and a pioneer in its remarkable contemporary revival - provides a superb new edition of Epictetus's celebrated guide to the Stoic philosophy of life (the Encheiridion) along with a selection of related reflections in his Discourses.

Marcus Aurelius, one of the great rulers of the Roman Empire, sets forth a series of self-reflective essays intended as a guide for his own self-improvement. Written during the turning points of his life and divided into twelve books, Meditations ponders life’s greatest questions in the author’s search for a meaningful existence. Remarkably, they are no different from the questions we ask ourselves today - from finding happiness to understanding our place in the cosmos. Centuries after Aurelius’s death, Meditations remains a profound source of inspiration.

Ralph Waldo Emerson was an American philosopher and writer best known for leading the transcendentalist movement of the mid-19th century. He was also a heavy influence in romanticism or the Romantic era. Through his lectures, essays, and poems, Emerson championed individualism and following one's intuition, believing one will become a more moral and idealistic person in so doing. This collection is eight of Emerson's essays from The First Series published in 1841 and The Second Series published in 1844 including "Self-Reliance", "Circles", and more.

While politicians, entrepreneurs, and even school children could tell you that sustainability is an important and nearly universal value, many of them, and many of us, may struggle to define the term, let alone trace its history. What is sustainability? Is it always about the environment? What science do we need to fully grasp what it requires? What does sustainability mean for business? How can governments plan for a sustainable future? 

Lucius Annaeus Seneca, known as Seneca the Younger (c. 4 BC - AD 65), is the author of On the Shortness of Life (c. 49 AD). In it, Seneca draws insight from different streams of ancient wisdom: Stoic, Epicurean, Platonic, Skeptic and Cynic, as he addresses some of the important questions humans face. Seneca encourages people to be mindful of time and to use it purposefully. He suggests awareness and acceptance as a remedy for many worries and wasteful dissipations.

Marcus Aurelius ruled the Roman Empire from AD 161-180. He wrote the 12 books of the Meditations as a source for his own guidance and self-improvement. It is possible that large portions of the work were written at Sirmium, where he spent much time planning military campaigns from 170 to 180. Some of it was written while he was positioned at Aquincum on campaign in Pannonia, because internal notes tell us that the first book was written when he was campaigning against the Quadi on the river Granova and the second book was written at Carnuntum.

'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.

La proclamación neoliberal de la libertad se manifiesta en realidad como un imperativo paradójico: sé libre. Domina una economía de la supervivencia en la que cada uno es su propio empresario. El neoliberalismo, con sus desinhibidos impulsos narcisistas del yo y del rendimiento, es el infierno de lo igual, una sociedad de la depresión y el cansancio compuesta por sujetos aislados.
