"The Dress Isn't Blue or Gold Because Color Doesn't Exist"



I didn't say that.  But Professor of Neuroscience, Beau Lotto, basically says as much:. 
Color is, quite literally, a figment of your imagination, Lotto said. It only exists in your head. Bevil Conway, a neuroscientist who studies color and vision at Wellesley College [where Hillary Clinton went], explained it this way: “Color is this computation that our brains make that enables us to extract meaning from the world.”
“A color only exists in your head,” Lotto said. “There’s such a thing as light. There’s such a thing as energy. There’s no such thing as color.”
So let's get this straight: Color only exists in your head.  It ain't on that thing you're looking at; it's a computation in your head. And there's no such thing as color--that is, color doesn't exist.  It exists in your head and it doesn't exist in your head because there is no such thing as color.  Got that?

That wall you painted blue, the blue was in your head.  You put paint on the wall but not blue paint.  As well, if you have ever seen a brain--presumably what you have seen are colors arranged in a certain brain-shaped pattern.  If you've seen a brain, the brain was in your head.  The brain was a computation in your brain.  (Except that the brain you've seen doesn't exist).

And you thought philosophy was nuts!

[A new liar's paradox? This statement is both blue and false.]

The Dress

What two colors do you see on the dress?





Serendipitous that I should come across this today.  We were talking about Descartes' skeptical arguments in Intro to Phil, and a student came up to me after class and presented me with an inverted qualia argument she had been thinking about. [I should add that "The Dress" doesn't seem designed to raise the inverted qualia argument in particular, though it certainly brings to mind issues about qualia more generally].

For what it's worth, the dress appears to me as gold and white (a bluish white to be exact and brownish gold).  In better lighting conditions it would appear to be white and gold.  Definitely not blue and black.
