Kant is arguably the most influential modern philosopher, but also one of the most difficult. Roger Scruton tackles his exceptionally complex subject with a strong hand, exploring the background to Kant's work and showing why the Critique of Pure Reason has proved so enduring. 

Ludwig Wittgenstein (1889-1951) was an extraordinarily original thinker, whose influence on 20th-century thinking far outside the bounds of philosophy alone. In this engaging Introduction, A. C. Grayling makes Wittgenstein's thought accessible to the general listener by explaining the nature and impact of Wittgenstein's views. He describes both his early and later philosophy, the differences and connections between them, and gives a fresh assessment of Wittgenstein's continuing influence on contemporary thought. 

The influence of Aristotle, the prince of philosophers, on the intellectual history of the West is second to none. In this book, Jonathan Barnes examines Aristotle's scientific researches, his discoveries in logic and his metaphysical theories, his work in psychology and in ethics and politics, and his ideas about art and poetry, placing his teachings in their historical context. 

Schopenhauer: here's when great philosophy can be somber, pessimistic, even brutal, and still resonate with a sarcastic laugh. He was among the first to contend that the universe is essentially not a rational place; in his most famous work, "The World as Will and Representation", he argues that the individuals of a species do not have as much free will as is ordinarily thought, as the only Will that matters is that of the species, which is to reproduce and carry on. Schopenhauer is very well-known for his radical stance on women, aesthetics, and rhetoric; he is the author of "The Art of Being Right", a playful manual designed to utterly crush one's opponent in verbal battle, and of the "Metaphysics of the Love of the Sexes", a hilarious application of the theories developed in the "World as Will and Representation".

Counsels and Maxims is a classic work by noted German philosopher Arthur Schopenhauer. His work has influenced some of the modern world's greatest thinkers, including Carl Jung, Sigmund Freud, and Erwin Schrödinger. This piece was originally translated by Thomas Bailey Saunders. 

哲学者とはいかなる人物なのか．何を，どのように，考えているのか．思考を極限まで厳密に突き詰めたがゆえに実践的であるという，驚くべき哲学プログラムを作り上げたスピノザ

E. H. Gombrich's world history, an international best seller now available in English for the first time, is a text dominated not by dates and facts but by the sweep of experience across the centuries, a guide to humanity's achievements, and an acute witness to its frailties.

Hegel is regarded as one of the most influential figures on modern political and intellectual development. After painting Hegel's life and times in broad strokes, Peter Singer goes on to tackle some of the more challenging aspects of Hegel's philosophy. Offering a broad discussion of Hegel's ideas and an account of his major works, Singer explains what have often been considered abstruse and obscure ideas in a clear and inviting manner. 

Descartes is perhaps best known for his statement, "Cogito, ergo sum," the cornerstone of his metaphysics. But he did not intend the metaphysics to stand apart from his scientific work, which included important investigations into physics, mathematics, and optics. In this book, Sorell shows that Descarates was, above all, an advocate and practitioner of the new mathematical approach to physics, and that he developed his philosophies to support his discoveries in the sciences.
