With the help of leading scientists and philosophers, the episode explores the theories and experiments that have attempted to answer this age-old question.

The episode begins with an examination of the brain and how it interprets signals from the outside world. Viewers are introduced to the concept of "perception," which refers to how we interpret sensory information such as sight, sound, and touch. Through interviews with experts, the episode delves into the ways in which our brains can sometimes trick us into perceiving things that aren't actually there, such as optical illusions.
