Let's get metaphysical! This episode focuses primarily on Parmenides (6th - mid-5th century BCE), the "father of metaphysics". He believed that a lot of what we see and believe in (concepts such as creation and movement) are actually an illusion and that reality is unchanging. 

I'll discuss Parmenides's theory, argument, and influence and take some side-trips into the philosophy of physics - looking at theories of what was before the Big Bang and (my favourite topic) the nature of time!
