I assume he was pissed with the gods. They were keeping their mouths shut, dear, very firmly. And, i think, this is why he decided to write, or to say the following :
Firstly, and first of all, there is nothing.
Secondly, and second, if there is something, it is impossible for the man to understand it.
Thirdly, and third, even if the man is able to understand it, he is not able to explain it.
Ps : Pissed ! With the gods ! For sure and for good ! Let me play a song.
