What is the fundamental nature of reality? What is time? What is space? Is there a God? Is the world around us ‘real’? What is change? Do numbers exist? What is causation, and can there be such a thing as a ‘first cause’? Why is reality like it is? What does it mean for something to exist? Why does anything exist?
These are just a few of the questions posed by the oft-derided, mind-melting realm of metaphysics, perhaps the most obscure of philosophy’s four core branches.
