What is a proof?

[Mystic]

Here is what I don't find a proof.

So and so heard from so and so who heard from so and so whom heard from so and so that so and so said....

And then so and so and so and so say so and so are trustworthy and so and so are not therefore this report of so and so is authentic but so and so is not.

That's not proof and is nothing but a delusion of knowledge.
