Entertaining and insightful, David Hume's Dialogues Concerning Natural Religion and The Natural History of Religion are considered to be among the most important philosophical works on the topic of religion. Each investigates the formation and consequences of religious belief.

In On the Genealogy of Morals, subtitled "A Polemic", Nietzsche furthers his pursuit of a clarity that is less tainted by imposed prejudices. He looks at the way attitudes towards 'morality' evolved and the way congenital ideas of morality were heavily colored by the Judaic and Christian traditions.

A Treatise of Human Nature is the first work ever published by David Hume, a man who revolutionized our understanding of philosophy. Hume was an advocate of the skeptical school of philosophy and a key figure in the Scottish Enlightenment. He looks at the nature of human experience and cognition, showing that philosophy and reason can only be reflections of our nature.

From the perspective of an unbeliever, Fear and Trembling explores the paradox of faith, the nature of Christianity, and the complexity of human emotion. Kierkegaard examines the biblical story of Abraham, who was instructed to sacrifice his son Isaac, and forces us to consider Abraham's state of mind. What drove Abraham, and what made him carry out such an absurd and extreme request from God? Kierkegaard argues that Abraham's agreement to sacrifice Isaac, and his suspension of reason, elevated him to the highest level of faith.

Written in the form of a letter to a Frenchman, Edmund Burke's Reflections on the Revolution in France is an impassioned attack on the French Revolution and its hasty destruction of the Church, the old elites, and the Crown. Burke tackles the new republic and its allegiance to principles such as liberty and equality, as well as its failure to recognize the complexities of human nature, society, and wisdom accumulated over time, contending that gradual change and adjustment is far better than immediate upheaval.

The Republic poses questions that endure: What is justice? What form of community fosters the best possible life for human beings? What is the nature and destiny of the soul? What form of education provides the best leaders for a good republic? What are the various forms of poetry and the other arts, and which ones should be fostered and which ones should be discouraged? How does knowing differ from believing?

In The Madness of Crowds Douglas Murray investigates the dangers of ‘woke’ culture and the rise of identity politics. In lively, razor-sharp prose he examines the most controversial issues of our moment: sexuality, gender, technology and race, with interludes on the Marxist foundations of ‘wokeness’, the impact of tech and how, in an increasingly online culture, we must relearn the ability to forgive.

Plagued with doubt and uncertainty in sensory knowledge, Descartes is struck with the idea that everything he knows is false. He considers the possibility that he has been deceived by an 'evil demon' and is left with nothing to lean on, until he arrives at the phrase 'cogito ergo sum' ('I think, therefore I am'). Among the most quoted philosophical works in history, Meditations on First Philosophy and Discourse on the Method together display the full workings of Descartes' skeptical method and the formation of his famous phrase.

Composed in four parts between 1883 and 1885, Thus Spoke Zarathustra is the most famous and influential work of German philosopher Friedrich Nietzsche. The work is a philosophical novel in which the character of Zarathustra, a religious prophet-like figure, delivers a series of lessons and sermons in a Biblical style that articulate the central ideas of Nietzsche's mature thought.

"Call me Ishmael." Thus starts the greatest American novel. Melville said himself that he wanted to write "a mighty book about a mighty theme" and so he did. It is a story of one man's obsessive revenge-journey against the white whale, Moby-Dick, who injured him in an earlier meeting. Woven into the story of the last journey of The Pequod is a mesh of philosophy, rumination, religion, history, and a mass of information about whaling through the ages.

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".

Childe Harold's Pilgrimage is a fascinating portrait of 19th-century Europe - disillusioned and ravaged by the wars of the postrevolutionary and Napoleonic eras. Our protagonist, whose breathtaking journey eerily echoes Byron's own life story, forgoes his destiny back home for the exciting unknown - the nature of humanity and the transformative effects of travel burst through the pages in four powerful cantos of Spenserian stanzas. Here is the poem that set Byron on his meteoric rise to fame in London society.

Werther, a sensitive young artist, finds himself in Wahlheim, a quiet, attractive village in Germany where he seeks solace from the turmoils of love. It is a young spring, and he hopes that arcadian solitude will prove a genial balm to his mind. But his romantic tendency rules otherwise, and he falls in love with Charlotte - Lotte - even though he knows she is affianced to another.

In A Philosophical Enquiry, Edmund Burke sets out to define the nature of beauty and sublimity, and establish an objective criterion for discussing aesthetics. His definition of beauty as rooted in pleasure and sexuality, and the sublime in pain and survival, aligned him with the empiricists John Locke and David Hume, as he replaced the metaphysics of Plato's aesthetics with a psychological and physiological perspective.

Man is born free, and everywhere he is in chains. In The Social Contract, Rousseau explores the concept of freedom and the political structures that may enable people to acquire it. He argues that the sovereign power of a state lies not in any one ruler but in the will of the general population. Rousseau argues that the ideal state would be a direct democracy where executive decision making is carried out by citizens who meet in assembly, as they would in the ancient city-state of Athens.
