Sometimes a single sentence sums up an entire worldview and then outlasts centuries, living on in posters, speeches and everyday conversation. Behind every famous quotation stands a mind that interpreted the world in its own way. This pack turns the question around: it is not the quote that is sought, but the thinker behind it. Who said it? Match the sayings to their authors: the questioning Socrates and René Descartes with his I think, therefore I am, the provocative Friedrich Nietzsche and Thomas Hobbes with his bleak view of humanity, the freedom-loving Jean-Jacques Rousseau and the duty-bound Immanuel Kant, the existentialist Jean-Paul Sartre and the science pioneer Francis Bacon, the power-politician Niccolò Machiavelli and the ancient Heraclitus, the sophist Protagoras and the language-critical Ludwig Wittgenstein: recognise from whose pen each thought flows and discover the people behind the great words. In the process, a handful of clever sentences becomes a little journey through the history of human thought.
