Immanuel Kant's Groundwork of the Metaphysics of Morals stands as a towering achievement in moral philosophy, on par with Plato's Republic and Aristotle's Nicomachean Ethics. This profound work seeks to uncover and establish the supreme principle of morality: the categorical imperative.

Kant compellingly argues that every human being is an end in themselves, never to be treated merely as a means by others. He posits that moral obligations are an expression of our inherent capacity for autonomy or self-governance. These obligations are not just rules but laws of freedom, reflecting our highest nature.

This edition includes an insightful introduction that delves into Kant's arguments, providing clarity and context for modern readers.

The Gay Science, often considered the most personal of all Nietzsche's works, presents a rich tapestry of philosophical reflections and poetic expressions. In this book, Nietzsche proclaims the death of God and introduces readers to his doctrine of eternal recurrence.

Walter Kaufmann's commentary, enriched with many quotations from previously untranslated letters, brings to life Nietzsche as a human being and illuminates his philosophy. This work contains some of Nietzsche's most sustained discussions on art and morality, knowledge and truth, the intellectual conscience, and the origin of logic.

Written just before Thus Spoke Zarathustra and finalized five years later, after Beyond Good and Evil, this book captures many of Nietzsche's most interesting philosophical ideas and the largest collection of his poetry that he ever published himself.

Engage with Nietzsche's thought and explore themes of art, science, morality, and human existence with a spirit of joy and inquiry.

Human Action: A Treatise on Economics by Ludwig von Mises is a profound and comprehensive examination of economic principles. Mises delves into the intricacies of market phenomena, presenting them as the results of countless conscious, purposive actions, choices, and preferences of individuals. Each person strives to attain various wants and ends while avoiding undesired consequences.

Individual Choices: It is the subjective value judgments of individuals that ultimately determine market phenomena such as supply and demand, prices, the pattern of production, and even profits and losses. While governments may attempt to set "prices," it is individuals who, through competitive bidding for money, products, and services, actually determine them.

Economics as a Study of Human Actions: Mises presents economics not merely as a study of material goods, services, and products, but as a study of human actions. He introduces the science of praxeology, a discipline grounded in reason and logic, which acknowledges a regularity in the sequence and interrelationships among market phenomena.

The Impact of Free Market Policies: Mises attributes the tremendous technological progress and increased wealth and general welfare in the last two centuries to liberal government policies based on free-market economic teachings. These policies created an environment of freedom and peace, allowing individuals to pursue their respective goals.

The Futility of Government Regulation: Mises explains the futility and counter-productiveness of government attempts to regulate and control individuals' circumstances. He argues that men are born unequal, and it is precisely their inequality that fosters social cooperation and civilization.

Ludwig von Mises (1881–1973) was a leading figure of the Austrian School of Economics in the twentieth century. His work continues to be a significant reference in the field of economics.

The teaching of G. I. Gurdjieff (1866-1949) has come to be recognized as one of the most original, enduring, and penetrating of our century. While Gurdjieff used many different means to transmit his vision of the human dilemma and human possibility, he gave special importance to his acknowledged masterwork, Beelzebub's Tales to His Grandson.

Beelzebub's Tales is an "ocean of story" and of ideas that one can explore for a lifetime. It is majestic in scale and content, challengingly inventive in prose style, and often approached with apprehension. This revised edition, prepared under the direction of Gurdjieff's closest pupil, Jeanne de Salzmann, offers a new experience of Gurdjieff's masterpiece for contemporary readers.

This edition provides a translation that clarifies the verbal surface while respecting the author's thought and style. It is presented in a sturdy cloth edition, echoing its original publication.
