Are Anti-Particles Just Particles Traveling Back In Time?

Abstract: Richard Feynman has claimed that anti-particles
are just particles traveling back in time. According to standard
textbooks this is not so. I will discuss who is right. I argue that
Feynman's view is plausible in classical physics but that matters
are not so clear in quantum field theory.
