Philosophers & Key Ideas

12 questions · Philosophy

For over two thousand years they have posed the questions humankind still wrestles with today: what is truth, what is just, how should one live? From the marketplaces of Athens through the studies of Königsberg to the schools of wisdom in China, great thinkers laid the foundation of our worldview and often changed whole ages with a single thought. This pack gathers the most influential philosophers in history: recognise Socrates, who led to insight through questions, his student Plato with the theory of Forms and Plato's student Aristotle, the founder of logic, René Descartes with the famous I think, therefore I am and Immanuel Kant with the categorical imperative, Friedrich Nietzsche with his revaluation of all values and John Stuart Mill with utilitarianism, Jean-Jacques Rousseau with the social contract and Georg Wilhelm Friedrich Hegel with his dialectic, Karl Marx with the critique of capitalism, Jean-Paul Sartre with existentialism and the Chinese sage Confucius: recognise them by the ideas that still shape our thinking today.
