It can be said of very few books that the world was changed as a result of its publication - but this is certainly the case of Capital: A Critique of Political Economy by Karl Marx (1818-1883). Volume 1 appeared (in German) in 1867, and the two subsequent volumes appeared at later dates after the author's death - completed from extensive notes left by Marx himself.

Following Marx’s death in 1883, Engels was able to step into the breach and, drawing on Marx’s extensive notes and writings, complete volume 2 of Capital, leading to its publication in 1885. Here, Marx turns his attention to the money owner, the money lender, the wholesale merchant, the trader and the entrepreneur or 'functioning capitalist.'  

Published in 1894, 11 years after the death of Marx himself, Capital Volume 3 was the product of the untiring and meticulous work of Friedrich Engels working from Marx’s outline and notes and carried the subtitle The Process of Capitalist Production as a Whole. In seven parts, Marx and Engels were determined to demonstrate that private property, competition and the market economy driven by the profit motive must lead to the demise of capitalism. 

State and Revolution (1917) describes the role of the state in society, the necessity of proletarian revolution, and the theoretic inadequacies of social democracy in achieving revolution. It describes the inherent nature of the state as a tool for class oppression, a creation born of one social class' desire to control all other social classes. Whether a dictatorship or a democracy, the state remains in the control of the ruling class.

Without question one of the most significant books in modern history, The Communist Manifesto is a brief, populist pamphlet that distils the core ideas of communism into accessible prose. Published just months before violent uprisings threatened to destabilise much of the European establishment, it outlines a view of history as a constant battle between the classes that will inevitably result in revolution.

The Republic, Plato's masterwork, was first enjoyed 2,400 years ago and remains one of the most widely read books in the world. Presented as a dialogue between Plato's teacher Socrates and various interlocutors, it is an exhortation to philosophy, inviting its listeners to reflect on the choices to be made if we are to live the best life available to us. This complex, dynamic work creates a picture of an ideal society governed not by the desire for money, power or fame, but by philosophy, wisdom and justice.

In January 2015, Yanis Varoufakis, an economics professor teaching in Austin, Texas, was elected to the Greek parliament with more votes than any other member of parliament. He was appointed finance minister, and, in the whirlwind five months that followed, everything he had warned about was confirmed as the "troika" (the European Central Bank, International Monetary Fund, and European Commission) stonewalled his efforts to resolve Greece's economic crisis.

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".

Vladimir Ilyich Ulyanov (1870-1924) is better known by his alias Lenin. A Russian revolutionary, politician, and political theorist, he served as the head of government of Soviet Russia from 1917 to 1924 and of the Soviet Union from 1922 to 1924. Under his administration, Russia became the Soviet Union, a one-party state governed by the Communist Party.  

In this combative, controversial book, Terry Eagleton takes issue with the prejudice that Marxism is dead and done with. Taking 10 of the most common objections to Marxism - that it leads to political tyranny, that it reduces everything to the economic, that it is a form of historical determinism, and so on - he demonstrates in each case what a woeful travesty of Marx's own thought these assumptions are.

The book explains the differences between utopian socialism and scientific socialism. Engels claimed that scientific socialism derives from reality and is based on the materialist conception of history. Engels begins by describing the thoughts of Saint-Simon, Fourier, and Robert Owen. In Chapter Two, he discusses dialectics, and Chapter Three is a summary of dialectics in relation to economic and social struggles. 

In 1965, the US government helped the Indonesian military kill approximately one million innocent civilians. This was one of the most important turning points of the 20th century, eliminating the largest communist party outside China and the Soviet Union and inspiring copycat terror programs in faraway countries like Brazil and Chile. But these events remain widely overlooked, precisely because the CIA's secret interventions were so successful.

This 100-year-old book still explains our endless wars. As the extraordinary death and suffering of World War I unfolded, Vladimir Ilyich Lenin tried to explain why so many nations agreed to sacrifice so many people in such a brutal way. Expanding on the works of other political and economic theorists, including Karl Marx, Lenin provided an answer: Capitalism. In Imperialism: The Highest Stage of Capitalism, Lenin extends his scorn to the international socialist movement.

In a single volume, the seminal writings of the world's leading philosopher, linguist, and critic, published to coincide with his 80th birthday. For the past 40 years Noam Chomsky's writings on politics and language have established him as a preeminent public intellectual and as one of the most original and wide-ranging political and social critics of our time. Among the seminal figures in linguistic theory over the past century, since the 1960s Chomsky has also secured a place as perhaps the leading dissident voice in the United States.

First published in 1936, Keynes’ ideas had evolved during the difficulties following World War 1 in Europe, and the US crash and the Depression of the 1920s-'30s and the misery of mass unemployment. He deplored the situation where a few individuals or companies stored massive wealth while vast numbers experienced poverty and insecurity (his alarm bells ring today!) and sought to promote initiatives where governments could intervene with social projects to keep money fluctuating.
