Considered to be one of the most important philosophical works of all time, the History of Western Philosophy is a dazzlingly unique exploration of the ideologies of significant philosophers throughout the ages - from Plato and Aristotle through to Spinoza, Kant and the 20th century. Written by a man who changed the history of philosophy himself, this is an account that has never been rivaled since its first publication over 60 years ago.

This metaphysical self-help classic instills happiness within and urges individuals to pursue a content life without sin, boredom, or contempt. Written decades ago with post-war depression in mind, this text has transcended time and continues to give applicable advice for modern-day individuals.

The Problems of Philosophy discusses Bertrand Russell's views on philosophy and the problems that arise in the field. Russell's views focus on knowledge rather than the metaphysical realm of philosophy. The Problems with Philosophy revolves around the central question that Russell asks in his opening line of Chapter 1 - Is there any knowledge in the world which is so certain that no reasonable man could doubt it?

Dedicated as few men have been to the life of reason, Bertrand Russell has always been concerned with the basic questions to which religion also addresses itself - questions about man’s place in the universe and the nature of the good life, questions that involve life after death, morality, freedom, education, and sexual ethics. He brings to his treatment of these questions the same courage, scrupulous logic, and lofty wisdom for which his other work as philosopher, writer, and teacher has been famous.

These 15 lectures have been hailed as milestones in modern psychology as they explore the relation between mind and matter under a completely new scope. Living in the turbulent years after World War I and having been deeply influenced by realists and behaviorists of the early 20th century, Russell attempts to reconcile the paradoxical materialistic view of contemporary psychologists on mind with the anti-materialistic tendency that physicists adopt over matter.

Perhaps one of the most revolutionary works of philosophy ever presented, The Phenomenology of Spirit is Hegel's 1807 work that is in numerous ways extraordinary. A myriad of topics are discussed, and explained in such a harmoniously complex way that the method has been termed Hegelian dialectic. Ultimately, the work as a whole is a remarkable study of the mind's growth from its direct awareness to scientific philosophy, proving to be a difficult yet highly influential and enduring work.

Bertrand Russell wrote that mathematics can exalt "as surely as poetry". This is especially true of one equation: ei(pi) + 1 = 0, the brainchild of Leonhard Euler, the Mozart of mathematics. More than two centuries after Euler's death, it is still regarded as a conceptual diamond of unsurpassed beauty. Called Euler's identity, or God's equation, it includes just five numbers but represents an astonishing revelation of hidden connections.

Infinite Powers recounts how calculus tantalized and thrilled its inventors, starting with its first glimmers in ancient Greece and bringing us right up to the discovery of gravitational waves. Strogatz reveals how this form of math rose to the challenges of each age: how to determine the area of a circle with only sand and a stick; how to explain why Mars goes "backwards" sometimes; how to turn the tide in the fight against AIDS.

Does time exist? What is infinity? Why do mirrors reverse left and right but not up and down? In this scintillating collection, Holt explores the human mind, the cosmos, and the thinkers who’ve tried to encompass the latter with the former. With his trademark clarity and humor, Holt probes the mysteries of quantum mechanics, the quest for the foundations of mathematics, and the nature of logic and truth. Along the way, he offers intimate biographical sketches of celebrated and neglected thinkers, from the physicist Emmy Noether to the computing pioneer Alan Turing and the discoverer of fractals, Benoit Mandelbrot.

A good book may have the power to change the way we see the world, but a great book actually becomes part of our daily consciousness, pervading our thinking to the point that we take it for granted, and we forget how provocative and challenging its ideas once were - and still are. The Structure of Scientific Revolutions is that kind of book.

Being and Time was published in 1927 during the Weimar period in Germany, a time of political, social and economic turmoil. Heidegger himself did not escape the pressures and his nationalism, and undeniable anti-Semitism in the following decades cast a shadow over the man, but not the work. Being and Time is not coloured by expressions of his later views (unlike other writings) and remains an outstanding document.

Albert Camus' The Stranger is one of the most widely read novels in the world, with millions of copies sold. It stands as perhaps the greatest existentialist tale ever conceived, and is certainly one of the most important and influential books ever produced. Now, for the first time, this revered masterpiece is available as an unabridged audio production.

One of the most influential works of this century, The Myth of Sisyphus and Other Essays is a crucial exposition of existentialist thought. Influenced by works such as Don Juan and the novels of Kafka, these essays begin with a meditation on suicide; the question of living or not living in a universe devoid of order or meaning.

Elements of The Philosophy of Right, a key work in the output of Georg Wilhelm Hegel (1770-1831), appeared in 1820 - and was arguably his last major publication. His intention was to state his views on the philosophy of law, political and social theory and ethics. Appearing as it did in a crucial time for the Prussian state - still affected by the Napoleonic wars and their aftermath - it was viewed differently by those on both the left and the right of the political spectrum.

If you're like most people, geometry is a dimly remembered exercise you gladly left behind in the dust of ninth grade. It's plodding through a series of miniscule steps only to prove some fact about triangles that was obvious to you in the first place. That's not geometry. Okay, it is geometry, but only a tiny part, which has as much to do with geometry in all its flush modern richness as conjugating a verb has to do with a great novel. Shape reveals the geometry underneath some of the most important scientific, political, and philosophical problems we face.
