Good vs. evil.  Right vs. wrong.

​

Do we come with it built-in, or is it just a function of how we're raised?  Is there any objective "right" or "wrong," or does it just come down to culture and society?

​

In this unit, you'll start by looking at the theories of an ancient Greek philosopher: Plato.  Plato argued that people are born with perfect, "ideal" concepts in their minds - perfect beauty, perfect justice, etc. - and that everything they do is an attempt to reach them.  We'll compare his theories to some modern neuroscience to find out how much we're born with - and whether what we're born with is actually, objectively "moral" ...

... or not.
