This one is about the “Mary the colour scientist” philosophical argument by Frank Jackson.
Imagine a girl who had no ability to see colours from her birth. That pushed her to learn everything about colours. Now she is a famous scientist with literally universal knowledge in any colour-related topic. Physics, physiology, psychology – you name it.
Her studies resulted in the treatment that helps her condition. Tomorrow she will see the colours for the first time. Will she get any new information from the red rose beside her bed?
