Every once in a while I experience a moment of deja vu. And ever since 1999, when I have that little frisson of deja vu, I say to myself, “Glitch in the Matrix.” I bet I’m not the only one. In addition to being a groundbreaking special effects movie, the Matrix has embedded itself in our collective consciousness. And if you’d like to find out where the premise came from, check out tonight’s Chicago Public Library lecture at the Bucktown-Wicker Park Branch (1701 N. Milwaukee Ave., 312-744-6022) tonight at 7: “From Plato to Neo: The Philosophy of the Matrix”: “The Matrix was inspired by Plato’s Myth of the Cave and contains many cultural and philosophical references. Lecture with clips presented by Claire Campini, Ph.D.”
