Foolish Game of the Gods

I have two principles as a human being:

1. Never lie.

2. Never believe anything anyone says, including myself.

“Sir, I must point out that your second principle contradicts the first.”

“Where’s the contradiction?”

“If you never lie, why don’t you believe what you say?”

“Oh, sorry, I forgot to mention, I don’t consider myself a human being.”

...

Allow me to introduce myself. My name is Cheng Shi. Cheng Shi, who never lies.

What, you haven't heard of me?

It's fine, you just haven't been deceived by me yet.

Soon, you'll remember.
