The Colour Blind Man

This is a philosophical thought experiment that I came up with at school.

---------

Imagine a 'colour blind' person. What we see as green, he sees as red and what we see as red, he sees as green.
Surprisingly, nobody would ever know. Why?
First, to explain, I will invent two new words.

• Gred - The colour we see as red but he sees as green
• Reen - The colour we see as green he sees as red.

Now, imagine this man as a baby. His parent points to a gred object, and teaches him it is red. His parent then points to a reen object, and says it is green. Now, this person calls anything he percieves as green "red", and anything he percieves as red "green".

So, in later life, when he is asked 'What colour is this?' about a reen object, even though he sees it as red, he will call it green. So, from the outside, he would be indistinguishable from a non-colourblind person.

Real Life Waterbe?!?

Well, not quite. Yet. They are green, so they can't be Waterbe. But we do have intelligent lizards. Look:

This is a lizard solving a feeding puzzle designed for birds. Birds are a bit more intelligent that reptiles, so these reptiles must be pretty smart.

Basically, what happens is there are two caps: a yellow one and a blue one. Underneath the blue one, there is a worm. Underneath the yellow onbe, there isn't a worm.

To get the food, the lizard needs to use its intelligence to flip the caps over until it finds the one with food under it. It can then eat the worm, and then wait until the next day when it is hungry again.

The researchers found that, form day-to-day, the lizards where able to figure out how to flip the cap and figure out which cap contained food, even with a waiting period of 24 hours.

At least they won't develop bipedalism and war, right guys? Guys? Where is everyo
