All Ravens Are Black

All ravens are black

But really
Who dicided that all ravens are black

Although you have not seen every raven in the world
Everyone you have seen is black

So there is a good chance that they are all black
And you dicided that for a fact
They are all black

But what if someone showed you a white raven
Your mind would change in an instant

But all ravens are black

And in the same way a person beleaves there is no life after death
There are no white ravens

But what if I said I had seen a white raven
Just one single white raven

What then?
