The book deals with the greatest ideas of mankind from various spheres of life. Humanity in different periods of its development gave rise to many great ideas. Some ideas, such as Reason, Soul, Evolution, Theory of Relativity, are delighted, others, like Fascism, Racism, War, plunge a person into horror. The main body of Big Ideas, of course, gave rise to philosophy and its eternal opponent - religion. Faith, Fate, Freedom, Evil and other fundamental concepts are fundamentally important for understanding the meaning of human life. A huge mark in the history of mankind was left by political ideas, many of which define our civilization now: Democracy, Conservatism, Islamism, Liberalism and others. Of course, among the Big Ideas there are many ideas from the field of science and art: Quantum Mechanics, Classicism, Romanticism, Big Bang.
