Seeing is believing, except when it’s not. Our eyes can tell us one thing and its opposite simultaneously, causing a suspension of disbelief. Cognitive dissonance. It can be somewhat unsettling. Our brains are hardwired to react first and think later, compounding the reaction. We want to believe, and so we do.
I’ve always admired the work of the surrealists: Magritte, Dali, and Escher. They are the masters of the visual non sequitur. No other genre of work offers the surety of realism with the uneasy realization that something is not quite right.
