Philosophy and Terry Pratchett book where I have my bit too is out now. Here is a short motivation to look up for it:
"It's time to pick up your fedora and embark on a philosophical journey through Discworld! Terry Pratchett is world-famous for the narrative verve and surreal humour of his novels. But now meet another Terry Pratchett – a man of serious metaphysical ideas and sophisticated philosophical insights. In Philosophy and Terry Pratchett thirteen professional philosophers survey such key philosophical issues as personal identity, the nature of destiny, the value of individuality, the meaning of existentialism, the reality of universals and the existence of alternative realities. In considering these and many other equally fascinating themes, close reference is made to more than 35 Discworld novels as well as to the ideas of some of history's greatest philosophers including Aristotle, Hobbes, Rousseau, Kant, Mill, Kierkegaard, Wittgenstein and Rawls. During your journey, you will be surprised by numerous provocative conclusions including the startling claim that the existence of Discworld is logically possible!".
