external world

What's out there

The external world is reality outside one's own mind—the physical universe of objects, other people, and events that exists independently of any individual's perception or thoughts.

The term appears most often in philosophy, where skeptics question whether we can truly know anything beyond our own mental experiences: How can we be certain the external world isn't an elaborate illusion?
