Time, a Useful Illusion

Time does not exist, according to modern physics. Yet somehow you experience it in all its dynamic, flowing glory. You don't really move through time as a single persisting being, so feeling that you're not the same person as before is literally true. Last, time flies when you're having fun-and drags when you aren't.

In Time, a Useful Illusion, Ronald Gruber takes you on a mind-bending journey of discovery through time illusions. He introduces the Dualistic Mind Theory, explaining how the brain experiences physical time. Learn how virtual reality offers the brain a reliable version of time travel.

Time is dead. Yet illusions of time shape who we are. Certain illusions, such as persistence and being present, allow us to have what we believe to be free will. Time is an illusion, but it's an important one that makes us human.
