The Critique of Pure Reason is a work that examines the faculty of reason and the qualities inherent in human thought. Before this time the influence of the knower on that which was sought to be known was not considered in a thorough and developed manner. Kant attempted with this critique to establish a limit to the knowable based on the nature of human cognition. His work was an attempt to address the failings in philosophy and metaphysics and provide a solid foundation for the proper use of reason to expand knowledge.

In 81 brief chapters, Lao Tzu's Tao Te Ching, or Book of the Way, provides advice that imparts balance and perspective, as well as a serene and generous spirit. It teaches us how to work for the good with the effortless skill that comes from being in accord with the Tao: the basic principle of the universe.

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.

John Locke and his works - particularly An Essay Concerning Human Understanding - are regularly and rightly presented as foundations for the Age of Enlightenment. His primary epistemological message - that the mind at birth is a blank sheet waiting to be filled by the experiences of the senses - complemented his primary political message: that human beings are free and equal and have the right to envision, create and direct the governments that rule them and the societies within which they live.

Socrates is in prison, sentenced to die when the sun sets. In this final conversation, he asks what will become of him once he drinks the poison prescribed for his execution. Socrates and his friends examine several arguments designed to prove that the soul is immortal. This quest leads him to the broader topic of the nature of mind and its connection not only to human existence but also to the cosmos itself. What could be a better way to pass the time between now and the sunset?

For much of his life, historian Howard Zinn chronicled American history from the bottom up, throwing out the official version taught in schools - with its emphasis on great men in high places - to focus on the street, the home, and the workplace. Known for its lively, clear prose as well as its scholarly research, A People's History of the United States is the only volume to tell America's story from the point of view of - and in the words of - America's women, factory workers, African-Americans, Native Americans, the working poor, and immigrant laborers. 

By calling everything into doubt, Descartes laid the foundations of modern philosophy. With the celebrated words "I think therefore I am," his compelling argument swept aside ancient and medieval traditions. He deduced that human beings consist of minds and bodies; that these are totally distinct "substances"; that God exists and that He ensures we can trust the evidence of our senses.

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.

Continuing where Thus Spoke Zarathustra left off, Nietzsche's controversial work Beyond Good and Evil is one of the most influential philosophical texts of the 19th century and one of the most controversial works of ideology ever written. 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".

Dorothea Brooke is an ardent idealist who represses her vivacity and intelligence for the cold, theological pedant Casaubon. One man understands her true nature: the artist Will Ladislaw. But how can love triumph against her sense of duty and Casaubon’s mean spirit? Meanwhile, in the little world of Middlemarch, the broader world is mirrored: the world of politics, social change, and reforms, as well as betrayal, greed, blackmail, ambition, and disappointment.
