Philosophy classes often face the challenge that the original texts of great thinkers are too lengthy and complex. This little book provides a solution: in fictional conversations with contemporary individuals, the philosophers themselves speak and explain in a way that is accessible to students what the categorical imperative, utilitarianism, the social contract, the allegory of the cave, and many other central ideas in the history of philosophy are all about. This creates opportunities for critical questions and lively discussions. The voices of Plato, Aristotle, Thomas Hobbes, John Locke, David Hume, Jean-Jacques Rousseau, Immanuel Kant, Jeremy Bentham, John Stuart Mill, Karl Marx, Wilhelm Dilthey, Karl Popper, Hans Jonas, Arnold Gehlen, and Peter Singer are all represented.
