In philosophy, zombies are beings that are exactly like human beings in every single way except one. A philosophical zombie might talk about how great the coffee is, they might drive to work and answer the phone, they might go home and walk the dog. However, philosophical zombies lack one thing: consciousness. If it is possible that a being could be physically identical to a conscious human and yet lack consciousness, then consciousness must involve something more than physical matter. We discuss the zombie argument and some of its problems.
