Imagine that your brain is floating in a tank and being stimulated by a computer to make you perceive an entire world around you. How do you know that this world really exists? Can you really be sure that your brain isn't just floating in a chemical solution?

What is right? What is real? And who am I, after all? Philosophy asks life's big questions. We present these questions as animated thought experiments, and thereby show how fascinating and entertaining it is to ponder life.
