language and thought, metaphor, space and time.
Humans are brilliant. We think and talk extensively about complex concepts like free will, love, and time -- concepts we can't experience directly through our senses like sight or touch. One way we do this is through metaphor: we compare these complex ideas to ones we can experience more directly when we say things like I'm looking forward to the future or that someone is battling depression. How does metaphor shape the way we perceive and reason about the world?
