Perception Is Not Reality

Nothing to add to what I’ve already said here. I just wanted to share another example of how our senses fill in what they expect rather than what is.

This photo is in black and white. It uses coloured grid lines to trick your brain into perceiving colour.

In other news, I just started reading Daniel Dennett’s classic Consciousness Explained. It starts with Brain in a Vat. Given that it was written in the late ’80s and published in the early ’90s, so it’s a bit behind the curve on the technology front. Artificial Intelligence—at least Machine Learning—wasn’t nearly as developed, and he didn’t quite grasp how fast and fast hardware and chip technology would advance in some 30 years. But this doesn’t alter the frame—just some peripheral details.

I’m not really even interested in consciousness. I favour Dennett’s take that consciousness is to the brain as wet is to water, so there’s not really any there there to find.
