It is a common tactic, going back to the beginnings of religion and philosophy, to presume that we are enveloped in a world of untruth and illusion, thereby fueling our movement toward truth. But the accumulation of skepticism has made us skeptical that truth can be found, so many of us have abandoned the quest all-together, yet we continue to believe in the reality of illusion, if only implicitly and locally. Here we challenge the concept of illusion itself, asking those who have ever called something âan illusionâ to question the meaning of these assertions. This broader skepticism partially annihilates itself, pushing us forward in the process.
