Pascal Wallisch

[instrumental music] And now we return to our program.

My name is Pascal Wallisch, and I serve as a professor at New York University.

Pascal is a neuroscientist.

He first saw the dress the evening it went viral.

It's a picture [laughs] off the internet.

Very quickly it ramps up to being very existential, and it's marvelous in that way.

For his book, David spent time with Pascal Wallisch, and he thinks the existential meaning of the dress is all tied up with a term Pascal taught him.

He introduced this word into my vocabulary, disambiguation.
